Q1. Briefly explain the maintenance systems that are practiced in production/service units by

providing few examples.

Maintenance Management Systems

Maintenance activity is defined and managed as a process in order to achieve maximum

pay off. Hence there is a need to identify a maintenance management system that helps the

organisation to work within an integral ‘Life cycle management model’ covering all the

machineries and equipments.

Optimum performance of the maintenance management system and process will happen

when the organisation encourages a close working between the production and

maintenance department. It also makes these departments jointly responsible for achieving

success in their business plans.

There are many critical areas and factors contributing for realising the best performance

and some of them are listed below:

· The valuable assets of the company must be maintained with a focus on the importance

of their functions, as these leads to the desired performance target.

· The effective maintenance is to preserve the asset for its high rate of performance and not

just preserving for the function alone.

· Process need to be established in order to efficiently manage maintenance activity and then to

evaluate the performance against targets. For this, the maintenance department has to evolve a

suitable maintenance system and processes that ensures continuous improvements in the

performance. This process evolved will act as a model and is useful throughout the asset life cycle

of the machinery or equipment. This type of model is explained as “Life cycle management

system’, under section 2.3.

· Maintenance crew and the supervisory personnel in the maintenance department need to

know their roles, responsibilities, and goals to be achieved, using system as means to

achieve them. This concept of combining asset life with the management processes is also

termed as ‘Asset Management’.

· A systematic program evolved by the maintenance management will increase the

efficiency of the personnel working, resulting in the increased life of the machineries and

hence the profitability. There must be a synergy in total operations. The following factors

contributes to the synergy:

· There must be fixed goals for the use and care of the productive assets.

· Both maintenance and production should work together and develop systems and

procedures for effective performance

· As profitability is the criteria, both performance and durability targets should become the

drivers

· All resources must be utilised optimally to achieve success in the process.

· Resource management or asset management requires sound decision making by the

respective authority for working effectively in the system. There must be opportunities in

the system to constantly improve upon and obtain the best business value for the

organisation

After learning about the maintenance management system and realising the critical areas

and factors for obtaining best performance, let us now get a brief description on the asset

life cycle management.

Q2. What are the three stages in the lifecycle management of any machinery? Explain in brief

the Life cycle management system?

Q3. Explain briefly the metrics that can be developed by the maintenance department to

identify the gap and take action to achieving the desired level of performance

Q4. Distinguish between preventive and breakdown maintenance citing examples.

Q5. “Organisations normally adopt a combination of one or more of the above methods.

And these options are justified if the resultant savings are more than the total costs

associated with any one of these methods” –Substantiate this statement.

Cost implications of maintenance practices

Q6. A valuable tool for improving maintenance effectiveness is to use fault tree analysis. What

does this tree means and how it is used as a valuable tool for electrical, hydraulic and other

complex systems in isolating physical components using circuits and attends to the problem?

(Book ID: B1340)

Assignment - Set- 2 (60 Marks)

Note: Each Question carries 10 marks. Answer all the questions.

Q1. What are the maintenance planning principles? How they contribute to the success of

planning?

Planning Principles

There are six principles of planning and these are:

1. Organising planning functions with separate responsibility and identity.

2. Making planners to concentrate on future works as one of their primary tasks.

3. Asking planners to maintain simple base files as part of their work systems.

4. Training planners to expertise their job and dictate the job requirements through their

dedicated work plans.

5. Helping planners to recognise the skill of the crafts required and arrange.

6. Organising planners to work sample their tasks while execution and hence measure the

planning effectiveness.

Let us look into each of these in detail:

1. Organising planning functions with separate responsibility and identity

In this principle, the planning function is organised as a separate function. Personnel who

are most experienced and having expertise as craft maintenance crew are selected and

assigned to the planning section. This type of selecting within the department and

assigning a separate function will further facilitate specialisation not only in planning

processes, but also focuses on the future works to be executed.

It is better that these identified Planners report to a different supervisor who will be responsible

to providing direction and has an obligation to complete the assigned work in an expeditious

manner, with a minimal interruptions.

Dear Students,

The planners should engage in preparatory works. Planning activities must flow smoothly

across the maintenance department. Planners need to work closely with the maintenance

crew for proper execution of work with consistency. The crew members will focus

exclusively on executing assigned work, and gain advantageous position as all the

preparatory works involved is accomplished by concerned planner.

Planning contributes to scheduling also. This scheduling is done in such a manner that the

maintenance department will utilise all their resources optimally. The lack of planning

effort may decrease the number of work assignments to crew members.

2. Making planners to concentrate on future works as one of their primary tasks

Principle of planning is forward thinking with a foresight. By preparing jobs in advance,

the planning facilitates improvement in labor productivity and allows the maintenance

crew to start their assigned job without waiting for any resources or with blockages.

After assigned job is completed, the lead technicians or the supervisor gives feedback to the

Planning section. The feedback consists of any problems the crew faced while executing the work,

any changes they did in the original plan during the execution, and any other information for the

planner to use in preparing future plans and schedules. The planners ensure that they will use this

feedback in their future planning to improve the overall effectiveness. This valid feedback

information as a record is filed separately for their future reference and use.

Dear Students,

3. Asking planners to maintain simple base files as part of their work systems

Planning maintains a simple and secured file system, with the file code numbers indicated

on it. A separate file is created for each equipment or machinery that is available in

production shops and those within the purview of the planning section. Each file will have

proper indications of the specific tag number of such machines. This type of file system

enables planners to utilise the equipment data and the experience of the previous work. It

also helps planners to prepare and improve the future work plans. The cost incurred for

each of the previous tasks is also recorded in these equipment files.

In case any decision was taken to replace the equipment or its costly parts, the same is also

recorded. As the majority of the maintenance tasks are repetitive in nature over a period of time,

this type of maintaining exclusive files with information of work plans, cost and so on, will help

assists planners or plant engineers to take suitable decisions on the repair or replacement. All

concerned are duly trained on how to use the information from these file for decision making.

Dear Students,

4. Training planners to expertise their job and dictate job requirements through their

dedicated work plans

Planners use their personal experience and the information available in the file system, as

explained above, to develop work plans. Primary responsibility of planners is to avoid

anticipated work delays through their plans that include the requirements of quality and

safety. To prepare such job plans, which improves the overall productivity, planners will

rely greatly on their personal skills and experience, apart from using the existing data or

information in the equipment files. In case of any unusual maintenance tasks must be

carried out and earlier such issues have not propped up, the planners will then consult and

take necessary help from Plant Engineering or Production departments.

5. Helping planners to recognise skills of the crafts required and arrange

The Planning section should recognise skills of the crafts required when firming up the scope of

the maintenance work. Planners obtain clarifications from the indenting section as to what skills

they propose to have in the person for such maintenance jobs. They also ask the intending

sections for suggestions, which will help in having a better coordination. The planners then evolve

the general strategy for the work to be done such as repair or replace, preventive or breakdown

policy. In case procedures for carrying out a job are not specified in the system file, the planners

must also evolve a strategy to lay out the procedures for carrying out that job.

Dear Students,








Best Regards, Admin


This principle dictates that planners calls for a minimum craft skill in the job plan and

hence, it depends on the available workforce being sufficiently skilled to execute the job.

Accordingly, the craft technicians will use their expertise to make the specified repair or

replacement.

Here again the planners and technicians work together over repeated jobs to develop better

procedures and checklists. Supervisors must train technicians, wherever applicable and

give proper support and guidance. Technicians must execute the job as planned without

much deviation. Any deviations from the job plan is required, there must be an approval

from the planner before proceeding.

Planners give information required for supervisor to schedule the job and control required

while executing. Skilled technicians give the feedback on the executed job plans, thus

contributing additional information for future plans.

6. Organising planners to work sample their tasks while execution and hence measure

the planning effectiveness
