The major functions of this department are:-
1. Organization Problems of the Production Planning Department
The production planning department decide the clear picture about its
objectives and well organized the objectives.
(A) Section which compiles and records information relating to:
(i) The amount of materials and components in stock;
(ii) The orders placed by customers;
(iii) Available plant or plants;
(iv) Capacity of plant or plants : and
(v) Operations, process and times & involved.
As the section contains systematic and valuable reports in regard to different
aspects, the top officials are directly or indirectly connected with this
department. This department must collect the relevant and adequate
information regarding stock, plant, equipment tools, fixtures, labour input,
production, depreciation, kind and quantity required by customers, delays
and improvements etc. it should also keep stores ledger car which may be of
three types : inventory details, record of consumption and general
information.
(B) Section which deals with serious and thoughtful consideration to
different schemes, operations, processes, tools, machinery and auxiliary
equipments etc. considerations are being materialized in writing and drawing
charts and figures on paper.
(C) Section which translates the plan into reality and controls results. This
section may be sub-divided into two sub-sections: (i) Sub-section which deals
with the theoretical aspects mainly of clerical nature. (ii) Sub-section which
DEPARTMENT OF MANAGEMENT
25
deals with the practical aspects. The production planning department must
adopt systematic methods of observation, inspection and reporting on
regular intervals. It must also see that necessary corrective measures and
modifications for the future should be made to obtain better results.
2. Necessary Facts Required for production planning Department
The production planning department is equipped with full fledged
information in regard to the following so that it may proceed smoothly its
production planning even in the time of unfavorable conditions:
a) Data regarding product engineering, design of the product, basic type of
processes and operations, assembly and sub-assembly methods.
b) Material specifications and standardization and the volume of raw-
materials required to obtain better economy on large scale.
c) The most advantageous sequence of operations and minimum production
cost.
d) Economic lots which will usher in most frequent turnover of inventories.
e) Fixtures, tools, jigs and dimensional gauging instruments which will be
required for production.
f) Information regarding normal and maximum capacity of the plant.
g) Rate of output per hour, per day, per week and per month.
h) Information as regards materials cost per unit, labour cost per unit and
overhead cost per unit.
i) Obsolescence and its rate and loss in storage.
j) Fixed rate of interest on invested capital.

technique and planning.
3. Putting Plans into Operation
Having decided when work shall be produced, authority must be given for it to commence
and instructions given to get material on the move and actually to do the work. Methods
for doing this vary from a copy of the customer's order to a detailed specification with part
list and drawings and detailed manufacturing instructions, with all supporting documents
for each part.
4. Planning Problem of developing plans
So much for the tools of loading; the technique can only be learnt by practice, but there are
several precepts which are generally applicable.
5. Records of Times and Capacities for Processes and Operations of facts
DEPARTMENT OF MANAGEMENT
27
The second type of basic data which must be compiled and made available is that which
has to do with processes and operations carried on in the factory. It is essential to have
readily available the operations, plant required and production times for all products,
parts and assemblies.
6. Stock Records of Facts
In a very few of the large mass-production units, materials flow straight into production
within a day or two of receipt, but nothing like this is possible in the majority of factories.
7. Compiling and Recording the Facts
The science of production planning consists broadly of relating what is wanted to what is
available, on a time basis,. Obviously, this can only be done if all the facts are known facts
relating to what has to be produced and when, and facts relating to capacities and
materials, available.

The purpose of this chapter is to present a review of literature relating to the
Information Technology and website management. Although Information Technology and
website management is an important ingredient in the smooth working of business entities,
it has not attracted much attention of scholars.
Ever since the evolution of the concept of Information Technology, several authors have
attempted to analyze the concept by defining it so that the components and concept of
information technology are properly identified. In doing so quantitative and qualitative
characteristics of webstes management and information technology are also identified to
make website for meeting specific needs. These efforts have offered further scope to the
authors to approach this topic in the context of management of components of website and
information technology in many ways. Such approaches have also facilitated evolution of
techniques to manage websites. Each these approaches has their own basis and
justification. Views expressed by various authors suggest further need to analyze website

Computers while large institution had at most a few dozen. The idea that within twenty
years equally powerful computers smaller than postage stamps would be mass produced by
the millions was pure science fiction.
The merging of computers and communications has had a profound influnce on the way
computer system are organized . The concept of the “ Computer Centres ” as a room with a
large computer to which users bring their work for processing their work as now totally
absolete. The old model of a single computer serving all of the organizational’s
computational needs has been replaced by one in which a large number of separate but
interconnected computers do the job. These systems are called computer networks. A good communication system is a must of every organization. Organization depend
on inter connected network of computer to serve their information processing needs. We
live in a network connected world,thus network is a group of two or more computer system
linked together.
Generally a communication network is any arrangement where a sender transnmit message to areceiver over a channel consisting of some type of medium.
Following are the five basic components that consist in networking:-
TERMINALS viz microcomputer,telephones,fax machine etc.
TELECOMMUNICATION PROCESSOR viz modems,multiplexer,front end.
DEPARTMENT OF MANAGEMENT
56
TELECOMMUNICATION & MEDIA viz telecommunication use combination of
media viz copper wires,coaxial cables,fiber optic cables microwave systems and
communication satellite system to inter connect the other component of a network.
COMPUTER-
A mainframe computer may served as a host computer for a large organization
network assisted by mini computers acting as network of end users micro computer
work stations.
TELECOMMUNICATION SOFTWARE-
Telecommunication software consist of programs that reside in host computer system,
Communication control computers and end user computer.
No matter how large and complex that real world networks may appear to be, their five
basic components must be at work to support a network.
DEPARTMENT OF MANAGEMENT
57
There are many types of networks . However from an end users point of view there are
three basic types:-
DEPARTMENT OF MANAGEMENT
58
LOCAL AREA NETWORK(LAN)A LAN connects network devices over a relatively short distance. A networked office
building, school, or home usually contains a single LAN, though sometimes one building
will contain a few small LANs (perhaps one per room), and occasionally a LAN will span a
group of nearby buildings. In TCP/IP networking, a LAN is often but not always
implemented as a single IP subnet.
In addition to operating in a limited space, LANs are also typically owned, controlled, and
managed by a single person or organization. They also tend to use certain connectivity
technologies, primarily Ethernet and Token Ring.
LANs are distinguished from other kinds of network by three characteristics:-
Their size
Transmission Technology and
Their Topology.
DEPARTMENT OF MANAGEMENT
59
METROPOLITAN AREA NETWORK (MAN)
A metropolitan area network (MAN) is a computer network that usually spans a city or a
large campus. A MAN usually interconnects a number of local area networks(LANs) using
a high-capacity backbone technology, such as fiber-optical links, and provides up-link
services to wide area networks (or WAN) and the Internet.
We can also define A metropolitan area network (MAN) is a network that interconnects
users with computer resources in a geographic area or region larger than that covered by
even a large local area network (LAN) but smaller than the area covered by a wide area
network (WAN). The term is applied to the interconnection of networks in a city into a
single larger network (which may then also offer efficient connection to a wide area
network). It is also used to mean the interconnection of several local area networks by
bridging them with backbone lines. The latter usage is also sometimes referred to as a
campus network.
Examples of metropolitan area networks of various sizes can be found in the metropolitan
areas of London, England; Lodz, Poland; and Geneva, Switzerland. Large universities also
sometimes use the term to describe their networks. A recent trend is the installation of
wireless MANs.
DEPARTMENT OF MANAGEMENT
60
A key aspect of MAN is that there is a broadcast medium(for 802.6 two cable) to which all
the computers are attached.
A MAN often provides efficient connections to a wide area network (WAN). There are
three important features which discriminate MANs from LANs or WANs:
1. The network size falls intermediate between LANs and WANs. A MAN typically
covers an area of between 5 and 50 km range. Many MANs cover an area the size of
a city, although in some cases MANs may be as small as a group of buildings.
2. A MAN (like a WAN) is not generally owned by a single organisation. The MAN, its
communications links and equipment are generally owned by either a consortium of
users or by a network service provider who sells the service to the users.
3. A MAN often acts as a high speed network to allow sharing of regional resources. It
is also frequently used to provide a shared connection to other networks using a link
to a WAN.
DEPARTMENT OF MANAGEMENT
61
WIDE AREA NETWORK(WAN)
As the term implies, a WAN spans a large physical distance. The Internet is the largest
WAN, spanning the Earth.
A WAN is a geographically-dispersed collection of LANs. A network device called a router
connects LANs to a WAN. In IP networking, the router maintains both a LAN address and
a WAN address.
A WAN differs from a LAN in several important ways. Most WANs (like the Internet) are
not owned by any one organization but rather exist under collective or distributed
ownership and management. WANs tend to use technology like ATM, Frame Relay and
X.25 for connectivity over the longer distances.

PROTOCOL
In information technology, a protocol (from the Greek protocol on, which was a leaf of
paper glued to a manuscript volume, describing its contents) is the special set of rules that
end points in a telecommunication connection use when they communicate. Protocols exist
at several levels in a telecommunication connection. For example, there are protocols for
the data interchange at the hardware device level and protocols for data interchange at the
application program level. In the standard model known as Open Systems Interconnection
(OSI), there are one or more protocols at each layer in the telecommunication exchange
that both ends of the exchange must recognize and observe. Protocols are often described
in an industry or international standard.

TOPOLOGYTopology is a logical extension of a data communication system. In a computer network,two or more computers (often referred to as nodes) are linked together with carriers and data communication devices for the purpose of communicating data and shairing resources. The term network topology refers to the way in which the nodes of a network are linked together. It determines the data paths that may be used between any pair of nodes in the network.
ARCHITECTUREComputer on networks are sometimes called nodes. Computers and devices that allocate
resources for a network are called SERVER.
NETWORK TOPOLOGIES
DEPARTMENT OF MANAGEMENT
64
As we have seen earlier, Topology is the geometric arrangement of the computers in a
network , common topologies include Star, Ring, and Bus.
RING TOPOLOGY:-
A ring network is a network topology in which each node connects to exactly two other
nodes, forming a single continuous pathway for signals through each node - a ring. Data
travels from node to node, with each node along the way handling every packet.
Because a ring topology provides only one pathway between any two nodes, ring networks
may be disrupted by the failure of a single link. A node failure or cable break might isolate
every node attached to the ring.
FDDI networks overcome this vulnerability by sending data on a clockwise and a
counterclockwise ring: in the event of a break data is wrapped back onto the
complementary ring before it reaches the end of the cable, maintaining a path to every
node along the resulting "C-Ring".
Many ring networks add a "counter-rotating ring" to form a redundant topology. Such
"dual ring" networks include Spatial Reuse Protocol, Fiber Distributed Data Interface
(FDDI), and Resilient Packet Ring.
802.5 networks -- also known as IBM Token Ring networks—avoid the weakness of a ring
topology altogether: they actually use a star topology at the physical layer and a
Multistation Access Unit (MAU) to imitate a ring at the datalink layer
Advantages
DEPARTMENT OF MANAGEMENT
65
Very orderly network where every device has access to the token and the opportunity
to transmit
Performs better than a bus topology under heavy network load
Does not require a central node to manage the connectivity between the computers
Disadvantages
One malfunctioning workstation can create problems for the entire network
Moves, adds and changes of devices can affect the network
Communication delay is directly proportional to number of nodes in the network
Bandwidth is shared on all links between devices
STAR TOPOLOGY:-
DEPARTMENT OF MANAGEMENT
66
Star networks are one of the most common computer network topologies. In its simplest
form, a star network consists of one central switch, hub or computer, which acts as a
conduit to transmit messages. This consists of a central node, to which all other nodes are
connected; this central node provides a common connection point for all nodes through a
hub. Thus, the hub and leaf nodes, and the transmission lines between them, form a graph
with the topology of a star. If the central node is passive, the originating node must be able
to tolerate the reception of an echo of its own transmission, delayed by the two-way
transmission time (i.e. to and from the central node) plus any delay generated in the central
node. An active star network has an active central node that usually has the means to
prevent echo-related problems.
The star topology reduces the chance of network failure by connecting all of the systems to
a central node. When applied to a bus-based network, this central hub rebroadcasts all
transmissions received from any peripheral node to all peripheral nodes on the network,
sometimes including the originating node. All peripheral nodes may thus communicate
with all others by transmitting to, and receiving from, the central node only. The failure of
a transmission line linking any peripheral node to the central node will result in the
isolation of that peripheral node from all others, but the rest of the systems will be
unaffected.
It is also designed with each node (file servers, workstations, and peripherals) connected
directly to a central network hub, switch, or concentrator.
Data on a star network passes through the hub, switch, or concentrator before continuing
to its destination. The hub, switch, or concentrator manages and controls all functions of
the network. It is also acts as a repeater for the data flow. This configuration is common
with twisted pair cable. However, it can also be used with coaxial cable or optical fibre
cable.
Advantages
DEPARTMENT OF MANAGEMENT
67
Better performance: star topology prevents the passing of data packets through an
excessive number of nodes. At most, 3 devices and 2 links are involved in any
communication between any two devices. Although this topology places a huge
overhead on the central hub, with adequate capacity, the hub can handle very high
utilization by one device without affecting others.
Isolation of devices: Each device is inherently isolated by the link that connects it to the
hub. This makes the isolation of individual devices straightforward and amounts to
disconnecting each device from the others. This isolation also prevents any non-
centralized failure from affecting the network.
Benefits from centralization: As the central hub is the bottleneck, increasing its
capacity, or connecting additional devices to it, increases the size of the network very
easily. Centralization also allows the inspection of traffic through the network. This
facilitates analysis of the traffic and detection of suspicious behavior.
Easy to detect faults and to remove parts.
No disruptions to the network when connecting or removing devices.
Disadvantages
High dependence of the system on the functioning of the central hub
Failure of the central hub renders the network inoperable
DEPARTMENT OF MANAGEMENT
68
BUS TOPOLOGY:-
A bus network uses a multi-drop transmission medium, all node on the network share a
common bus and thus share communication. This allows only one device to transmit at a
time. A distributed access protocol determines which station is to transmit. Data frames
contain source and destination addresses, where each station monitors the bus and copies
frames addressed to itself.
( a typical bus topology)
A bus topology connects each computer (nodes) to a single segment trunk (a
communication line, typically coax cable, that is referred to as the 'bus'. The signal travels
from one end of the bus to the other. A terminator is required at each to absorb the signal
so as it does not reflect back across the bus. A media access method called CSMA/MA is
used to handle the collision that occur when two signals placed on the wire at the same
time. The bus topology is passive. In other words, the computers on the bus simply 'listen'
for a signal; they are not responsible for moving the signal along.
DEPARTMENT OF MANAGEMENT
69
Advantages:
Failure of one of the station does not affect others.
Good compromise over the other two topologies as it allows relatively high rate of
data tansmittion.
Well suited for temporary networks that must be set up in a hurry.
Easy to implement and extend.
Disadvantage:
Require a network to detect when two nodes are transmitting at the same time.
Does not cope well with heavy traffic rates
Difficult to administer/troubleshoot.
Limited cable length and number of stations.
A cable brake can disable the entire network; no redundancy.
Maintenance cost may be higher in the long run.
Performance degrade as additional computers are added.
DEPARTMENT OF MANAGEMENT
70
FIREWALL
A firewall is a device or set of devices designed to permit or deny network transmissions
based upon a set of rules and is frequently used to protect networks from unauthorized
access while permitting legitimate communications to pass.
Many personal computer operating systems include software-based firewalls to protect
against threats from the public Internet. Many routers that pass data between networks
contain firewall components and, conversely, many firewalls can perform basic routing
functions.
TYPES OF FIREWALL
There are different types of firewalls depending on where the communication is taking
place, where the communication is intercepted and the state that is being traced.
1) Network layer and packet filters
Network layer firewalls, also called packet filters, operate at a relatively low level of the
TCP/IP protocol stack, not allowing packets to pass through the firewall unless they match
the established rule set. The firewall administrator may define the rules; or default rules
may apply. The term "packet filter" originated in the context of BSD operating systems.
Network layer firewalls generally fall into two sub-categories, stateful and stateless.
Stateful firewalls maintain context about active sessions, and use that "state information"
to speed packet processing. Any existing network connection can be described by several
properties, including source and destination IP address, UDP or TCP ports, and the
current stage of the connection's lifetime (including session initiation, handshaking, data
DEPARTMENT OF MANAGEMENT
71
transfer, or completion connection). If a packet does not match an existing connection, it
will be evaluated according to the ruleset for new connections. If a packet matches an
existing connection based on comparison with the firewall's state table, it will be allowed to
pass without further processing.
Stateless firewalls require less memory, and can be faster for simple filters that require less
time to filter than to look up a session. They may also be necessary for filtering stateless
network protocols that have no concept of a session. However, they cannot make more
complex decisions based on what stage communications between hosts have reached.
Modern firewalls can filter traffic based on many packet attributes like source IP address,
source port, destination IP address or port, destination service like WWW or FTP. They
can filter based on protocols, TTL values, netblock of originator, of the source, and many
other attributes.
Commonly used packet filters on various versions of Unix are ipf (various), ipfw
(FreeBSD/Mac OS X), pf (OpenBSD, and all other BSDs), iptables/ipchains (Linux).
Advantages
The primary advantage of packet-filtering firewalls is that they are located in just
about every device on the network. Routers, switches, wireless access points, Virtual
Private Network (VPN) concentrators, and so on may all have the capability of
being a packet-filtering firewall.
Routers from the very smallest home office to the largest service-provider devices
inherently have the capability to control the flow of packets through the use of
ACLs.
DEPARTMENT OF MANAGEMENT
72
Switches may use Routed Access-Control Lists (RACLs), which provide the
capability to control traffic flow on a "routed" (Layer 3) interface; Port Access
Control Lists (PACL), which are assigned to a "switched" (Layer 2) interface; and
VLAN Access Control Lists (VACLs), which have the capability to control
"switched" and/or "routed" packets on a VLAN.
Other networking devices may also have the power to enforce traffic flow through
the use of ACLs. Consult the appropriate device documentation for details.
Packet-filtering firewalls are most likely a part of your existing network. These devices may
not be the most feature rich, but when you need to quickly implement a security policy to
mitigate an attack, protect against infected devices, and so on, this may be the quickest
solution to deploy.
DEPARTMENT OF MANAGEMENT
73
2.Application-layer Firewall
Application-layer firewalls work on the application level of the TCP/IP stack (i.e., all
browser traffic, or all telnet or ftp traffic), and may intercept all packets traveling to or
from an application. They block other packets (usually dropping them without
acknowledgment to the sender). In principle, application firewalls can prevent all
unwanted outside traffic from reaching protected machines.
On inspecting all packets for improper content, firewalls can restrict or prevent outright
the spread of networked computer worms and trojans. The additional inspection criteria
can add extra latency to the forwarding of packets to their destination.
Application firewalls function by determining whether a process should accept any given
connection. Application firewalls accomplish their function by hooking into socket calls to
filter the connections between the application layer and the lower layers of the OSI model.
Application firewalls that hook into socket calls are also referred to as socket filters.
Application firewalls work much like a packet filter but application filters apply filtering
rules (allow/block) on a per process basis instead of filtering connections on a per port
basis. Generally, prompts are used to define rules for processes that have not yet received a
connection. It is rare to find application firewalls not combined or used in conjunction with
a packet filter.
DEPARTMENT OF MANAGEMENT
74
Also, application firewalls further filter connections by examining the process ID of data
packets against a ruleset for the local process involved in the data transmission. The extent
of the filtering that occurs is defined by the provided ruleset. Given the variety of software
that exists, application firewalls only have more complex rulesets for the standard services,
such as sharing services. These per process rulesets have limited efficacy in filtering every
possible association that may occur with other processes. Also, these per process ruleset
cannot defend against modification of the process via exploitation, such as memory
corruption exploits. Because of these limitations, application firewalls are beginning to be
supplanted by a new generation of application firewalls that rely on mandatory access
control (MAC), also referred to as sandboxing, to protect vulnerable services. An example
of a next generation application firewall is AppArmor included in some Linux distributions

RESEARCH METHODOLOGY
Research methodology is a way to systematically solve the research problem. It may be
understood as a science of studying how research is done scientifically. In it we study the
various steps that are generally adopted by a researcher in studying his research problem
along with the logic behind them.
In research methodology we not only discuss the research methods but also
consider the logic behind the methods we use in the context of our research study and
explain why we are using a particular method or technique.
Research process consists of series of the action or step necessary to effectively carry
out research and desired sequencing of these steps-

RESEARCH DESIGN
"A research design is simply the framework or plan for a study that is used as a
guide in collecting and analyzing the data. It is blueprint that is followed incompleting a
study".
According to Kiplinger, "research design is a plan, structure and strategy of
Investigation conceived so as to obtain answers to research questions and to control
variance.
“A Research Design is the arrangement of conditions for collection and analysis of
data in a manner that aims to combine relevance to the research purpose with economy in
procedure.” Research design is the conceptual structure within which research should be
conducted.
I visited to different departments of the company to collect information, which helped me
to understand the process and the nature of the organization.
The preparation of the research design, appropriate for a particular research problem,
usually involves the consideration of the following:
The means of obtaining the information.
The availability and skills of the researcher.
The time available for research.
The cost factors relating to research, i.e. the Information Technology available
for research.
DEPARTMENT OF MANAGEMENT
79
The research design used here is descriptive or diagnostic research.
DESCRIPTIVE RESEARCH - Descriptive studies, as their name implies, are
designed to describe something. For e.g.- the characteristics of users of a given product; the
degree to which product use varies with income, age, sex or other characteristics; or the
number who saw a specific television commercial. Despite the emphasis on description, it
should not be concluded that such studies should be simply fact gathering expeditions.
and on department wise.
The data are interpreted on the basis of age, sex, work experience and on department
wise
The research is being conducted to study the need and use of information
technology in the company.
DATA COLLECTION METHOD
The next step is to determine the sources of data to be used. The researcher has to decide
whether to collect primary data or depend exclusively on secondary data. The primary
data collection methods used is questionnaire and interview (structured and direct
interview method).
When a study is to be based on secondary data, whether partly or fully, it is necessary to
satisfy oneself that the data are quite suitable for the objectives spelt out by the study.
The various sources of collecting data in the project are:
Record Files
Company Site
Annual Report 2010

SAMPLING
The sampling method used here is random or probability sampling method.
In this study participants were Top management and executives working in DIESEL
LOCOMOTIVE WORKS VARANASI, Varanasi located in UP. The sample size taken is
100 employees. Out of which 40 are Top management employees and 60 are executives.
The average age of respondents was 35 years. The education standard of the participants
ranged from high school to M. Tech or MBA. with an experience of 1to 35years on the job.
Meaning:
In Probability Sampling all the terms in the population have a chance of being chosen in
the sample. Personal knowledge and opinion are used to identify the items from the
population that are to be included in the sample. A sample selected by Judgment Sampling
is based on someone's expertise about the population.
ANALYSIS OF DATA:
After the data have been collected, the researcher turns to the task of analyzing them. The
analysis of data requires a number of closely related operations such as establishment of
categories, coding, tabulation and then drawing statistical references. For analysis of data,
following tools are used:
DEPARTMENT OF MANAGEMENT
81
Statistical tools:
Statistical tools are also important and significantly help in data analysis and
interpretation. Tables, bar graphs and pie charts are used to show the trend of the
company and to compare the satisfaction level
Limitations of the project
Research facilitates decision making and is not a substitute of decision making. It
helps in providing alternative solution and is not the solution itself.
The topic is so broad to cover all the fields in just 6 weeks.
One of the constraints in the completion of project was the busy environment of the
organization.
Although Varanasi is not new for me yet the company is establish far away from
the city.
All the necessary data were not available to me due to company’s confidential

CONCLUSION
This report enables to find out the impact and importance of information
technology in Diesel Locomotive Works, Varanasi.
Conclusion can be easily drawn from the analysis presented in this report. Although
there are some aspects on which I have concentrated but I have tried to put over heart and

Information technology play an important role in any enterprise in improving the
bussiness. The technology helps to prevent an economic downturn from completely
derailing the business.
The faster a business expands the more use of information technology it will need for
improvement and increase in the performance of the business. Good management of
technology will generate chances to earn cash which will help to improve profits and reduce
risks.
Engineers use the technology to design the models of the locomotives and engine,and also
create a simulated environment that will help to understand the engineers that how the
models are going to perform.
