Abstract: The paper explores possibilities of differentiation in the marina market

through involvement in international programs related to the protection and

preservation of the natural environment. The growth and development of the

nautical tourism market encourages more investment in the improvement of

existing and construction of new marinas globally. Consequently, increasing the

quality of offered services and facilities, and the emergence of new competitors in

the marina market, there is a growing need for an appropriate differentiation. One

of the major factors for achieving competitive advantage and long-term business

success is distinction offer of some marinas in respect of its competitors.

Possession of certificates and awards by various world organizations that

implement programs to protect the natural environment is a good source of

differentiation. The most common type of awards is the Blue Flag. The Republic

of Croatia is a good example because the ratio of the marinas with the Blue Flag

and the total number of marinas gives it high position in Europe.

Keywords: differentiation, marina, competitive advantage, the Blue Flag.

Abstract: Sustainable development is a complex and multidisciplinary research

area of today’s science. The research of water security and climate change has a

considerable history at the National University of Public Service (NUPS). Taking

as its base an earlier research workshop (Military Ecological Footprint Centre), the

Ludovika research group for the Footprint of Public Service has been established

and through this an international research capacity emerged, based on which

NUPS may be one of the acknowledged research places of national higher

education. The article is based on certain chapter of the book entitled “Public

Service and Sustainability” and sets forth the most recent results of the researches

made in connection with the police. Future plans include the establishment and

operation of an excellence centre with the participation of an international

research network especially for Visegrad 4 countries.

Keywords: Sustainability, Public Service, Police, Carbon Footprint, Good State.

Abstract: This paper analyzes the basic characteristics of UV radiation and its

impact on the environment and human health. The principal source of UV

radiation is the Sun. As a part of the spectrum of the Sun radiation reaching the

Earth and being mostly absorbed in the atmosphere, it is an important factor in

the climate change that we are facing today. In this sense, UV radiation

represents a dangerous hazard due to its weaker and weaker absorption in the

depleted ozone layer of the Earth. This could lead to serious environmental and

health problems. Nowadays, in most developed countries, solar UV radiation is

monitored. The purpose of monitoring is to monitor the possible harmful effects

of UV radiation on living organisms on Earth, primarily on humans, as well as to

study the processes in the atmosphere related to solar UV radiation. Human

activity is the main cause of ozone depletion, but it can also be a solution to the

problem.

Keywords: UV Radiation and Protection; Environment; Health.

Abstract: The model consists of a four phase. In the first phase, the criteria on the

basis of which the optimal location of the apartment is selected is defined. By

discussing with the experts, the criteria for managing the apartment were set. In

the second phase, the evaluation of the experts on pre-defined criteria is collected

and the average values of expert assessments are calculated. The Best-West

method was used to determine the criterion coefficients. In the third phase, using

the mathematical methods VIKOR, MABAC, COPRAS, TOPSIS and MAIRCA, the

optimal location of the apartment is selected. The VIKOR model was taken for the

basic model of multi-criteria decision making. In the fourth phase, we analyzed

the sensitivity of the VIKOR model to the change in the weight criterion. For the

purpose of research, the software for ranking of variant solutions was developed.

The software was created in Excel program, in the form of Excel calculators, and

in Lingo and Matlab for solving mathematical (non) equations.

Keywords: alternative, criteria, weight coefficient, multi-criteria decision-making,

Abstract. The realization of every transport process with dangerous goods follows

a certain risk of unwanted event with harmful consequences. The risk can be

reduced if all the necessary measures and activities are taken, and one of the key

steps for effective risk management in the transport of dangerous goods is the

choice of a transport vehicle that transports dangerous goods. The aim of this

paper is to evaluate different transport vehicles using different methods of multi

criteria decision making. Model is tested on real problem from Oil industry of

Serbia (NIS). In this paper weight coefficients were obtained by AHP method,

based on expert knowledge. Model contains of six alternatives and seven criteria:

fuel consumption, price, volume, and engine power, failure of vital circuits,

maintenance costs and environmental impact. Problem is solved using MABAC

method, and results are compared with TOPSIS, EDAS, ARAS, COPRAS and

MOORA method. In the final phase of this model, stability of the obtained results

was checked through the sensitivity analysis. Spearman rank correlation

coefficient was calculated between the ranks obtained by various methods.

Keywords: tank truck selection, MABAC, MCDM methods.

Abstract: The evaluation of dishes represents basic activity in the structuring of

menu, which allows the optimal use of resources in order to fully satisfy the

expectations of users and restaurant management. This study presents a new

approach in menu evaluation using the MultiAttributive Ideal-Real Comparative

Analysis (MAIRCA) method, modified by application of rough numbers in

dealing with imprecision in group decision making. The model was successfully

tested on the menu of a collective nutrition restaurant, where the evaluation of six

existing breakfast dishes and a new dish that should replace the worst ranking

dish was carried out.

Abstract: In this paper, an experimental study on the determination of rolling

resistance coefficient was carried out. The experiment tested a total of six different

types of vehicles and calculated the rolling resistance coefficient, depending on

the condition of surface and the type of tyres. The study is focused on achieving

the main goals related to determining the impact of the interaction between tyres

and surface on the rolling resistance coefficient and the effect of the coefficient

values on fuel consumption. Motor vehicles were subjected to the "free stop"

method on a horizontal road. In doing so, vehicle speed was registered every 10

seconds from an initial speed to stopping. In order to eliminate an error of possible

roadway inclination or wind impact, the experiment was repeated five times on

the same road section, as well as in the opposite direction. The experimental study

was carried out during December 2016 and January 2017. Three sets of tyres were

used for each vehicle, the tyres with tread depths of 8 mm, 6-7 mm and 4-5 mm,

while the type of surface referred to dry and wet condition of the roadway. Both

hypotheses have been confirmed, which means that the interaction of tyres and

surface affects the value of rolling resistance coefficient that further affects fuel

consumption.

Abstract: The decision-making process in all areas requires understanding of a

number of elements involved in this process. In that, very important role have the

significance of the criteria on the basis of which evaluation or selection of

alternatives is carried out. In this paper, the Delphi method is expanded with

rough numbers for determining the relative weight of the criteria. The developed

approach allows determining the significance of criteria based on an expert

evaluation, which must be at least ten. The approach is demonstrated on the

example of evaluating performance indicators in transport based on the

assessment of 19 decision makers. A sensitivity analysis was performed in which

the SWARA method was applied which gives very similar results with a

developed approach. Taking into account both approaches, the only difference in

the rankings of the criteria is at the last position.

Keywords: Rough Delphi, weights of criteria, transport, key performance

Abstract: One of the main problems faced by SMEs in developing countries, but

also in our country, is access to affordable sources of external financing. Also, on

the other hand, financial institutions are reluctant to provide funding for small

and medium-sized enterprises, especially those at the beginning of its

development. One of the ways for both sides to be satisfied with the mutual

cooperation is to regulate the rules by which economic activity of small and

medium-sized enterprises is financed. In this paper we will try to find a model

rule by which small and medium-sized enterprises funding would be granted. We

believe that in this way the efficiency of the use of borrowed funds will increase

and thus the number of investments will increase. This would lead to an increase

in the number of small and medium-sized enterprises, and therefore to an increase

in employment, which would lead to the economic development of the Republic

of Srpska.

Keywords: Funding rules, regulation, small and medium enterprises, economic

Abstract: The quality of logistics services, if it is positive, can affect loyalty and

user's satisfaction. Therefore, it is necessary to constantly measure the quality of

the service and strive to improve its worst elements. The aim of this research is to

determine the quality of logistics services for the company Bosnaekspress d.o.o.

Doboj. To measure the quality of logistics services, one of the most well-known

and most frequently used models, the SERVQUAL model, was used. The

application of the SERVQUAL model allows obtaining concrete results for the

conducted research in order to work on possible improvement. Within the

SERVQUAL model, there are five key dimensions based on which a research team

conducted a customer's satisfaction survey to establish the level of customer's

satisfaction with the service offered by Bosnaekspress d.o.o. Doboj. Five key

dimensions are: reliability, safety, tangibility, empathy and capability. Each of

these dimensions has different significance for different users, what contributes

to easier determination of the logistics services' quality. The obtained results show

that users of logistics services of the given company are not satisfied with the

same, that is, the quality is poor, because all dimensions have negative values of

the difference in observations and expectations. A Signum test was applied for the

purposes of statistical conclusions and variance analysis to determine the

significance of significant changes on individual issues.

Key words: Quality of logistics services; SERVQUAL model; transport,

Abstract: The fact that conventional energy sources are exhaustive and limited are

increasingly encouraging research in the field of alternative and renewable energy

sources. The electricity generated by solar photovoltaic modules and panels

occupies an ever greater percentage in total electricity production, so it is clear

that photovoltaic systems are increasingly integrating with the existing electricity

network into one system or functioning as autonomous systems. The aim of the

research is to create a model based on the principles of the fuzzy logic and artificial

neural networks that will perform the task of predicting the maximum energy of

photovoltaic modules as accurately as possible. The prediction should facilitate

work in planning production and consumption, system management, economic

analysis. The most important methods used in the research are modeling and

simulation. Input and output variables are selected and in the ANFIS (Adaptive

Neuro Fuzzy Inference System) model a set of their values is presented. Based on

them it comes to the function of dependency. The prediction rating of the created

model was performed on a separate data set for testing and a model with the

lowest average test error value was selected. The performance of the model was

compared with the linear mathematical model, which led to the conclusion that

the ANFIS model gives more accurate results.

Keywords: prediction, ANFIS (Adaptive Neuro Fuzzy Inference System),

Abstract: Generating power using solar energy utilization has become more

attractive recently. Libya has a variety of renewable energy resources, and it can

provide a considerable portion of the energy demand for the country through

solar energy. Therefore, with such potential, it is irrational to neglect sharing of

solar energy in the Libya’s energy mix. Thus, giving attention to the development

of this industry is of a high priority decision, and selecting suitable site is a critical

step in the decision making process. This study displays a new way of defining

weight coefficients of criteria for determining optimal locations for the

construction of solar plants, which implies the application of SWARA and

DEMATEL models. This model was tested and validated on a case-study with

three criteria and ten sub-criteria. The results show that technical criterion is the

most important criterion, followed by economic criterion, and at last the

environmental criterion. SWARA and DEMATEL weights are aggregated by

means of a non-linear model in which higher values of the weights give a higher

combined value of the weight coefficient and vice versa. SWARA-DEMATEL

multi-criteria model goes beyond the restrictions of the one-sided application of

factors. In addition, this model enables a simultaneous display of the influence of

SWARA and DEMATEL weights information on the ranking of the alternatives.

Abstract: Many countries have shifted toward sustainable energy using wind

power plants. The increased energy demand stresses the decision makers toward

utilizing the renewable resources. The selection of the proper wind farm site is a

strategic decision, and is based on a group of criteria mainly considering the local

conditions of its surrounding environment The BWM-AHP hybrid model is

applied to determine weight coefficients of criteria for the construction of wind

farms in Libya. A list of six main criteria and twenty two sub-criteria is evaluated.

The results show that the most important criterion is safety and quality followed

by social impressions.

Abstract. Use of gasoline as dangerous substance is relatively highly represented.

Using gasoline as primary or secondary product in logistics subsystems causes a

great number of accidents. It's dangerous substance which shouldn't cause great

number of accidents because of its wide range of use. Gasoline is one of the most

common dangerous substances. Consequences of accidents with gasoline are

huge and if a range of accident is great, accident participants chances of survival

are very low. Consequences on human health after accident are permanent if

poisoning with carbon-monoxide appears, and beside of vital organs damage, it

comes to damaging of accident participants psychomotor skills. Statistic analysis,

which was applied in research, showed that consequences of the greatest number

of accidents is fire and explosion. Also, high percent of deceased participants is

very worrying. It indicates that attention should be paid on technological

solutions of devices whose drive energy is gasoline.

Keywords: gasoline, accidents, dangerous substances.

Abstract: This paper has analyzed a medium sized (TC 1) and small sized (TC 2)

transport company for passenger transport from the aspect of marketing mix

which include the following instruments: people, product, price, personal sale,

place and promotion. For the analysis of these instruments in the observed

companies, it was used a comparative method. By comparing companies from

practice many differences have been noticed in areas such as number of vehicles

companies own, number of employees, invested funds, incomes and expenses.

Apart from these differences it can still be concluded that companies are

successfully operating on the market and the can meet the demands of their users

on one hand, while being able to cover their costs and achieve profit on the other

hand.

Abstract: A passenger car is an integral part of people's lives for many years. It is

believed that on average, the passenger car is only 10 percent of its working life,

which means that the remaining ninety percent is stationed in one place - parked.

Then it is no wonder that, today in a large number of cities (especially smaller

towns), the primary problem of urban environment is the problem of parking. In

order to solve the problem of parking, it is first of all necessary to optimally design

the parking spaces within the offered city zone, provide the necessary number of

parking spaces, and then equip parking lots or parking spaces on the street. One

of the examples of cities that have the problem of street parking is the city of

Doboj, on which territory a survey was conducted in order to determine the basic

characteristics of parking. The research process implied an independent survey,

in which registrations of passenger cars parked at a given location were carried

out, and then on the basis of the collected data, the basic characteristics of parking

were determined. Given the obtained results of the conducted research, at the end

of the work, suggestions were made on how to improve parking services on the

city's Doboj

Abstract: Nautical tourism is one of Croatia’s fastest growing tourism products.

Owing to its natural features, Croatia has been recognized as an attractive nautical

destination. The network of 22 modern ACI marinas has been developed over the

past decades along the eastern shores of the Adriatic Sea. This is the biggest

Mediterranean chain of marinas that provide standardized facilities and services.

This paper discusses the business performance of one of them – the ACI marina

situated in the city of Split. Mathematical approach is necessary to analyze the full

potential of nautical tourism as these tools are used to perform calculations when

planning, designing and constructing marinas. In addition, mathematical

methods contribute to the enhancement of the business performance through

creating and processing of various statistical data, profit and loss calculation,

remuneration calculation, following the throughput of boats in marinas, etc.

Abstract: Performing activities and operations within the internal transport

require adequate transportation and manipulative means. In order to be able to

perform overload manipulations, storage, forklifts are most often used as means

of internal transport. Nowadays, all means of transportation have a great

influence on to the environment. Therefore, electrical forklifts are used very often

for performing transport-manipulative activities. The aim of the paper is the

application of the multi-criteria decision-making method for the best solution, ie

an adequate forklift that will meet all needs. The selection of a used electric forklift

was made using the Rough SWARA - ARAS model. The determination of the

relative weights of the criteria was made using the Rough SWARA method, while

the ranking was performed using the ARAS method. The results of this model

have shown that the most preferred alternative is the Forklift 5, ie the Still RX 60-

35 electric forklift.

Abstract: Arsenic (As) is released into the aquatic environment through a complex

combination of natural biogeochemical reactions and human interactions. The

presence of increased concentration of arsenic in water sources is considered to be

a global health risk. The problem of a large number of countries, as well as Serbia,

is the contamination of drinking water by arsenic. Research shows that the

importation of arsenic in the body even in small doses is very harmful. Except for

individuals who are professionally exposed to arsenic, the most important way of

exposure is personal intake through food and drink water, including drinks made

from drinking water. The mean daily intake of arsenic from the drinking water

should generally be less than 10 μg (recommended value World Healt

Organization - WHO). New criteria in evaluation quality of drinking water have

made necessarily development of new technologies, in order to fulfill the request.

During the last years development of nanotechnology are being studied

nanomaterials as adsorbents for the removal of various contaminants from water,

including arsenic. The paper presents contemporary research connected to

finding new technologies for removing arsenic from water, which would replace

current ones based on filtration through nanomaterials and the use of grain

adsorbents.

Abstract: Acquiring an adequate transportation and manipulative means for

warehouse operation is an extremely important task. A warehouse is a dynamic

system where the movement of goods is the most dominant activity. Therefore,

warehouse operations should be carried out using the appropriate transportation

and manipulative means. The aim of this paper is the selection of a forklift on the

basis of previously conducted evaluation using the AHP-MABAC model. The

AHP method was used to define the importance of criteria, while the ranking was

made by applying the MABAC method. In order to check the stability of the

model, the sensitivity analysis was conducted. Another three methods that give

identical results – SAW, ARAS and WASPAS were applied, and therefore the

ranks are in the absolute correlation.

Abstract: Unsignalized intersections are the type of intersections where traffic is

regulated by traffic signs and road markings. Usually, these are intersections

where at least one way is controlled by stop or yield sign and that way is called

minor road. The other way is designed like major road. These intersections are

recognized in the world like TWSC (two way stop-controlled) intersections and

the most common type of them that appears in our region are four-leg or three-

leg intersections. The minor left-turning movement performed at unsignalized

intersection is one of the most complex actions in traffic. In this paper is analyzed

specific three-leg intersection. Level of service is determined using the procedure

HCM 2000. Obtained results are shown that the worst level of service is at minor

left-turning approach.

Keywords: unsignalized intersection; minor movement; level of service.

Abstract: When defining criteria that have an influence on traffic accessibility, it

is necessary to take into account the specificity of a concrete urban unit. A large

number of authors base own research on a small number of traffic access criteria

using one of the decision-making methods. The methods on which research can

be based are multi-criteria decision-making in combination with fuzzy logic and

rough numbers that give relevant results and are widely applied in all fields of

science today. Thanks to these methods, for problems where is a large number of

solutions in which certain criteria are formed, a valid solution can be reached.

When using these methods, it is necessary to emphasize that there is a certain

degree of subjectivity of the decision maker, but this can be minimized using

fuzzy or rough numbers. The aim of this paper is to compare the significance of

particular criteria using the Fuzzy AHP method and the Rough AHP method,

which would show differences in the values of weight significance criteria and

their ranking.

Abstract: Mobile technology is the fastest-growing technology today, and the

latest researches show that the number of mobile technology users is increasing

on a daily basis. This is an opportunity for marketing managers to take full

advantage of mobile technology. The first things associated with mobile

marketing are certainly SMS and MMS messages, mobile sites, mobile search, but

also mobile applications, mobile games, mobile social networks, location based

mobile marketing and mobile phone payment applications. However, there’s an

impression that a gap between mobile marketing numerous possibilities and its

practical use still exists. This paper is the result of an extensive research of the

most successful mobile marketing campaigns, 35 case studies, which won some of

the first three awards (gold, silver, bronze) or entered the finals in various

categories for the use of mobile marketing tools, according to MMA (The Mobile

Marketing Association). The aim of this paper is to identify the most successful

mobile marketing strategies which can improve performances of a company

Abstract: Alkali-aggregate reactions in concrete pose a major problem that

reduces the durability and working life of construction objects, especially those

exposed a great deal of moisture and high temperatures. This paper analyzes the

causes and consequences of chemical reactions in concrete that lead to this

phenomenon, considering the types of aggregates used, cement types, additives

as well as environmental conditions that favor this appearance. In order to prevent

this phenomenon, it is necessary to use aggregates containing smaller amount of

amorphous silica in the case of an alkali-silica reaction, or a limited amount of

aggregates containing carbonates in the case of an alkali-carbonate reaction. It is

recommended to use a cement containing small quantities of alkalis, as well as

Portland cement with addition of granulated blast furnace slag, silica fume or fly

ash, and also reduced humidity in the concrete.

Abstract: The correct loading of goods wagons is essential to railway operators as

well as infrastructure managers and payers of transport services. Incorrect loading

is not just a threat to traffic safety but may result in the loss or damage of goods

and delays in goods delivery, as well as damage to railway infrastructure and

vehicles. Goods loading can therefore be treated as a traffic safety problem, which

is by all means a legal imperative – each business entity involved in goods

transport has certain obligations, responsibility and rights – and an optimization

problem - a railway operator wants to make the highest profit possible, whereas

all other business entities want to minimize their costs. This paper treats loading

as an optimization problem, with all applicable safety regulations being

formulated as mandatory constraints. In view of the fact that different kinds of

goods are loaded into different railcars under different rules, the paper limits itself

to the loading of palletized goods into covered railcars. In addition to standard

constraints related to the loading of railcars used in international transport, as well

as the railway line category and pallet type, the paper also analyzes a number of

specific constraints that may be of great practical relevance. The described

problem has been formalized as a zero-one integer linear mathematical

programming task and has been solved by using developed software. Several

numerical examples involving specific constraints have been presented and

discussed.

Abstract: Due to the specificity of the transport of dangerous goods, as well as the

obligations arising from the legislation regulating this field, all the actors of this

process are obliged to take special measures in order to avoid unwanted

consequences. Special attention is paid to the planning of the transport of

dangerous goods. One of the most important planning elements is choosing a

route for the transport of dangerous goods in urban areas. In order to take

preventive measures, risk assessment is carried out on the routes and the

minimum risk route is defined. In this paper, a new model for the selection of

routes for the transport of dangerous goods (hazmat) on the network of urban

roads is proposed. The model is based on multi-criteria risk analysis and

traditional Dijkstra algorithm (D-R model). D-R model is a new approach for

minimizing the cost and variety of risk criteria in hazmat routing, which

adequately takes into account and minimizes a number of risks on potential

routes. The model is based on route selection based on the absolute risk size. The

proposed routing model was tested on a real case and in a real urban hazmat

routing problem, in Serbia.

Keywords: Hazardous materials routing, Risk, Dijkstra’s algorithm.

Abstract: Transport of hazardous material (THM) represents a complex area in

which are involved a large number of participants. The imperativ of THM is

minimization of risks in the entire process of transportation from the aspect of

everyone involved in it, which is not an easy task at all. To achieve this, it is

necessary in it’s early phase to carry out adequate evaluation and selection of an

optimal transport route. In this paper, optimal route criteria for THM is selected

using new approach in the field of multi-criteria decision making. Weight

coefficient of this criteria were determined applying linear programming (LP).

Evaluation and selection of suppliers is determined by applying TOPSIS

(Technique for Order of Preference by Similarity to Ideal Solution) and MABAC

(Multiattributive Border Approximation area Comparison) methods. Proposed

route model was tested on the real example of the transport eurodiesel in Serbia.

Abstract: In the digital age, innovation activity is a key factor of competitiveness

and sustainable development. Тhe concept of a modern economy based on

innovations, which Serbia is developing according to the model of the European

Union, requires infrastructural support for innovations. Innovation infrastructure

has the function of the initiators of the restructuring of the business sector and

networking of the subjects of innovation activity. Successful implementation of

this task requires the implementation of the holistic marketing concept. The

holistic marketing concept has developed just as the need of the companies to

recognize and meet the new demands of the modern market. Applying the

concept of holistic marketing, through internal, integrated, relationship and

performance marketing, enables institutions of innovation infrastructure to

successfully implement their function. Institutions of innovation infrastructure,

such as science-technology parks, business-technology incubators and technology

transfer centers, develop marketing strategies and programs based on the concept

of holistic marketing. For these institutions is the challenge to create a holistic

marketing approach that would support innovation. Innovation requires just a

comprehensive and integrated approach to marketing, such as the holistic

marketing concept.

Abstract: The civil-military paradox emerged at the gap which irreconcilably

divides basic values of civil society and the values on which military organization

rests. This paper considers the paradox in a broader context of civil-military

relations. The authors point to the wrong ways of establishing supremacy of

civilian over military power concluding that it is impossible to physically

subjugate the army, and that its obedience is political and sociological

phenomenon. The key to understanding civil-military paradox, which is at the

same time central issue of civilian democratic control of the army, lies in political

culture, in accepting basic, essential political values on which democracy is

founded, in internalization and institutionalization of these values. It is also

emphasized the importance of the education of military staff in these processes.

Abstract: With the aim of maximizing the profit as much as possible, consulting

companies evaluate the competition and predict their own success in public

tenders. Predicting performance, respectively, evaluating competition make one of

the key preconditions for taking sustainable managerial decisions in construction

consulting companies. This paper presents a new decision-support system for

predicting the success of consulting companies in construction, based on a neuro-

fuzzy approach. The adaptive neural network is constructed on the basis of the data

collected during seven-year research (from 2010 to 2016). The adaptive neural

network architecture is defined using the Artificial Bee Colony algorithm. The

model presented enables decision makers to evaluate and predict company's

performance in public tenders in accordance with changing environmental

circumstances. The objective of this model is to enable companies to gain insight

into the existing potentials in relation to competition and to sustainably plan

activities for further upgrading and improvement of company's potential. The

model provides companies with sustainable business activities through evaluating

their own position on the market. During seven-year research, three empirical

variables are identified that affect the prediction of success in public tenders. In this

neuro-fuzzy model, input variables are described by fuzzy sets which are presented

by Gaussian membership functions. On the basis of expert judgment, unique

knowledge base is created allowing the rank prediction of the observed company.

Validation of the neuro-fuzzy model is carried out by testing with real data (239

public tenders) collected during the research

Abstract: In its strategic development documents, the Republic of Serbia

highlighted innovation as a key factor of competitiveness and sustainable

development. The concept of a modern knowledge-driven economy was chosen

for the European Union, which requires the investment of significant financial

resources in innovation activity. The current system of financing innovation does

not support sufficient innovation activity and the extremely unfavorable structure

of financial resources. It is necessary to develop a model of financing innovative

activities that will provide a greater number of adequate financial instruments for

supporting innovation and their diffusion in the economy. Model of financing

innovation activities should be developed and reformed with a view to allocation

of public resources are used in an optimal way and stimulate innovation. Also, a

mechanism should be created to increase the participation of the business sector

to the level of the EU countries. By financial analysis of certain performances of

current modes of financing innovation, we see "gaps" in the existing model in

Serbia. By further researching the observed gaps and using the leading models

from the models that compare Serbia, it is possible to improve the analyzed

performances. The development of an innovation financing model that provides

adequate financial instruments for innovation support is essential for Serbia to

join the European Research Area, which is a central element of the EU Lisbon

Strategy and the Europe 2020 agenda aimed at positioning the EU as the most

competitive and dynamic economy in the world, based on knowledge.

circumstances that have affected the operation is essentially an analysis of the

operational environment, which represents a composite unit made up of different

dimensions. Understanding all dimensions of the operational environment, their

dynamics and interactions, is one of the necessary preconditions for the success of

the operation. The social dimension of the operational environment more and

more diverse exhibits impact on current operations because of today's conflicts

take place among the population, have an effect on the population or by causing

the reaction of the population, which directly or indirectly affects the success of

the operations. Today, civil society is relevant and indispensable player in any

conflict, much more than before. Accordingly, this work has focused on the

overview of the process of this dimension actualization importance in

contemnporary warfare, with emphasis on the consideration of all aspects

through which it exerts its influence.

Abstract: The rapid advancement of information technology does not have the

same impact and speed of implementation in all social institutions. The army as

one of the pillars of the state, by nature, is not inclined to change and integration

of innovations into its information systems. One of the conditions for proper

functioning of the military system is operational, timely and comprehensive

logistics. Among many, one of the basic tasks of logistics is to store resources with

proper space optimization. Time, space and human resources can be saved by

creating software which would allow moving equipment, pallets and crates

whose dimensions and shape are pre-defined in 3D virtual military-type

warehouse. The methods to be used in the work are qualitative analysis of content

and deductions, where the focus will be placed on the analysis of normative

documents, scientific papers and books related to warehouse space and

equipment. In addition to the above mentioned methods, a pilot project will be

developed in the form of a program that will allow transfer of type crates, palettes

and equipment into a virtual military warehouse with adherence to the norms

related to floor load, load on the storage area and the usability of the storage space.

Keywords: warehouse, pilot-project program, optimization, army, logistics.

Abstract: Praga V3S, 3Mp, 6x6is light self-wheeled armoured anti-air vehicle with

cannons 30/2 mm M53/59, which is being used by defense and security forces in

realization of the daily assigned tasks, especially during civil wars on Balkan

Peninsula in the period of 1991-1999. After a while, Praga has been returned to the

operational usage in Serbian Armed Forces during 2015, thanks to it's possitive

effects on a battlefields during war in 90's. According to the complexity of Praga,

which development is based on improvement of one or more specific elements in

order to achieve tactical-technical requests, technical problems occur often and

need to be solved. A scientific methodology known as Theory of Solving Inventive

Tasks (TRIZ) can be used to resolve them very effectively. The aim of this paper

is to illustrate one possible way of applying TRIZ to solving problems that arise

when working with complex technical systems (TS), such as Praga. This paper

shows how to use 40 innovation principles and contradiction matrix 39x39 (TRIZ

tools) in solving possible problems. TRIZ methodology is based on the axiom that

shows that the development of all technical systems takes place according to

objective laws. It shows the way how to use innovation principles (how to chose

1 principle among 40) in solving of real technical problems and resolving technical

contradictions. Any TS can be described with 39 parameters contained in the

contradiction matrix, which provides a choice of the most efficient inventive

principle that should be applied.

Keywords: innovation principles, TRIZ, contradiction, Praga.

Abstract: With the help of technological and information changes, transport has

significantly contributed to the dynamism of economic life in the last 20 years and

has become the most important link of the logistics chain. Transport services have

a strategic role and primary importance in the application of logistics (which aims

to optimize the movement of cargo, that is, to increase the efficiency of transport

flows, through reducing costs and greater satisfaction of transport service users).

Making decisions, especially those at the strategic level, requires taking into

account several criteria. This paper presents the application of certain methods of

multi-criteria optimization ("Analytical hierarchical process -AAH" and "Multi-

criteria compromise ranking - VIKOR") for decision making in order to optimize

the transport process.

Keywords: Multi-criteria decision making, AHP, VIKOR, transport.

Abstract: On the territory of the Republic of Serbia, there are some of the largest

landslides in Europe, such as the Begaljica’shill and the Duboko on Umka. The

activation of the landslide does not take the space and time as a limitation and the

consequences can be devastating to people and material goods. Just the existence

of a landslide requires a reliable risk assessment of the protected value, because

the very existence of danger generates negative effects on them. The paper

presents the possibility of using an adaptive neural network in the risk assessment

of the landslide as the basis for building a more efficient system of protection

against this danger. The application of the method is done on the basis of the

current Manual on the methodology for making the assessment of vulnerability

from elementary and other accidents and Emergency Plans.

Keywords: landslides, risk assessment, fuzzy logic, ANFIS model.

Abstract: Given the fact that the period of Germanization of the language system

of the Serbian language, as a consequence of the current political events and

turmoil, left a trace in many areas of political, economic, social life, but also in the

field of vocabulary used in everyday speech, the question arises as to the

frequency of germanisms in the language of gastronomy (cookery, confectionery,

bakery, butchery) and to what extent original terms have undergone

modifications adapted to the lexical characteristics of the Serbian language. This

topic is certainly closely linked to the expected competence of future professional

staff on the use of appropriate terminology in L2. Considering the fact that the

terminology in gastronomy is only a segment of German for special purposes

(GSP), its purpose is to promote the ability of learners to communicate with

professionals and lecturers on gastronomy-specific topics and in professional

communication domains. The work aims to identify learning objectives and

didactic consequences and to offer some useful methodological guidelines in

language teaching. In order to achieve this, grammar and its progression are not

at the center of the teaching process, but they are permanent companions and

components of a vocationally oriented DaF lesson.

Key words: German as GSP, gastronomy, communication, terminology in L2

Abstract: Performance of every company is a result of many diferent factors such

as profitability, market share, sales, promotion as well as good relationships

between the employees. In hospitality industry these relationships particulary has

an impact on overall business result, because of diverity of individuals who

cooperate and share tasks together. Conflicts among these individuals or groups

are inevitable and imposible to resolve permanenty. Contrary to the traditional

understanding of the conflict, which led to conflicts beeing viewed as a negative

phenomenon, contemporary theories consider conflict as an opportunity to

redesign a more efficient and productive service system. In order to reduce

interpersonal conflicts, as the most common form of conflict in each organization,

it is necessary to know what leads to them. Purpose of this paper is to identified

the causal factors of interpersonal conflicts in hospitality companies and explain

the most common one.

Keywords: interpersonal conflicts; hospitality; causative factors, organizational

communication, performances.

IMPORTANCE OF GASTRONOMIC

MANIFESTATIONS OF EASTERN SERBIA FOR

TOURISM DEVELOPMENT

Abstract:Every region of any country has its own specific features, widely known

customs, cultural and historical heritage, as well as products of plant and animal

origin meant for cherishing the tradition of authentic food preparation. Tourists

are eager for new experiences, including the gastronomy experiences as well. The

tourist map of Serbia is rich in a large number of events, part of which is related

to the promotion of the local gastronomy products. The region of the Eastern

Serbia is famous for numerous events, with the majority of them being aimed at,

either directly or indirectly, promoting gastronomy. The number of gastronomy

tourists has been on the increase over the recent years. They are in search of new

tastes, groceries which are produced in the protected environment with a specific

form of preparation. Gastronomy events of the Eastern Serbia can offer tourists

the knowledge of food preparation and preservation tradition, an insight into the

old methods of food serving, the promotion of a destination and the increase of

the number of visitors. The use of gastronomy and ethnology resources can also

contribute to the region development and preservation of the domicile population

in the countryside. All these factors affect the promotion and development of a

certain region, as well as the development of Serbia in general.

Keywords: tourism, gastronomy, authenticity, tradition, experiences, promotion.

Abstract: Among numerous analytical methods for organizational level

evaluation, the method of process functions stands out as the most used. Aim of

any evaluation is to provide insight into the current state of affairs and, based on

observed imperfections, suggest measures for their removal. By using the method

of process functions one can evaluate the organization of business functions,

organizational units, work scope, business elements, workplaces, etc. In this paper

the method of process functions is used for evaluation of environmental

protection organization level, in conditions of uncertainty. All uncertainties are

described by linguistic terms modeled using triangular fuzzy numbers and

defuzzification of fuzzy preferences is made using Graded Mean Integration

Representation.

Keywords: fuzzy, evaluation, organization, protection, environment.

Abstract: The Analytical Hierarchical Process (AHP) is theoretical and

methodological concept of multi-criteria analysis which provides solid support to

both individual and group decision-making process and it is one of the most

broadly used in the world. However, the participation of more interested parties

(decision makers), makes the decision-making process more complicated, so

different approach is required compared to when deciding on an individual basis.

Synthesis of individual weights into group weights can be performed in many

ways, but the problem is how to deal with different consistency of many decision

makers. Accordingly, in this paper are presented some of the options for defining

individual weights of decision makers in group AHP synthesis.

Keywords: weights; decision makers; analytical hierarchy process; group

synthesis.

Abstract: Care about guest is the most important activity in the tourism and

catering sector, and it represents service, kindness, goodwill, professionalism, the

ability to react in a timely manner to the wishes and needs of guests. Customer

care can be defined as a permanent quality of service and professionalism in

dealing with guests, a high level of service that meets the expectations of guests

and affects their emotions. Since guests strongly experience, remember and

evaluate employee relationships, great importance is focused on direct

communication with the guest, but also on non-verbal communication

transmitted by speech of the body. The way we talk to guests, smile, visual

contact, empathy and readiness to understand and listen to guests are as

important as what we are telling them. This research used the personal interview

to determine the attitudes and satisfaction of guests with the quality of services.

The case study on examples of Belgrade hotels was used. Empirical research has

confirmed the hypothesis of research that care about costumer and the quality of

hotel services are a key factor in achieving and exceeding consumer expectations,

and that the role of management in detecting and removing failures is of

paramount importance for consumersatisfaction.

Keywords: guest care, Belgrade, catering, tourism, hospitality.

Abstract: The World Health Organization in its agenda on sustainable

development 2030 sets a goal to reduce the number of traffic-related accidents by

50%. According to the trend of reducing the number of traffic-related accidents

and the latest statistics report by SIA Bitola, we found that this is a very high goal

for our city and a great challenge which we could try to reach. Namely, we started

the pedestrian safety initiative by trying to provide infrastructural facilities and

elements that are planned and designed according to the security principles and

which correspond to the projected speed and road function, as well as safe

infrastructure for pedestrians, the elderly and persons with disabilities. The main

objective of this paper is to develop a case study methodology regarding the

selection of pedestrian crossing types on the case study location example. Namely,

the VISSIM simulation model for the studied location has been introduced, and

the general conclusions have been adopted based on the multi-criteria decision-

making process analysis. The most important aim is directed towards obtaining

pedestrian safety, as well as bearing in mind the role of pedestrian safety within

the current safety goals.

Keywords: pedestrian safety; pedestrian crossing, AHP, VISSIM simulation.
