- 1. Write short notes on:
- a) Need for maintenance management
Answer:Maintenance can be defined as a combination of all technical and associated administrative actions intended to retain equipment in, or restore it to, a state in which it can perform its required function. Industrial maintenance is interpreted in the context of industrial systems (such as production facilities, buildings, equipment, and
- b) Maintenance resources
Answer:Maintenance resourcesare Facilities, funding, personnel, spare parts, technical data, test equipment, tools, etc., available or provided for maintenance operations. Aspects of good planning, scheduling, and resource optimization of daily work are described in Chapter 24, Long Look-Ahead Plan.
- c) Decentralised maintenance
Answer:Decentralisation means diffusion of authority. The dispersal of authority of decision-making to the lower level management is termed as decentralisation. Decentralisation of authority is a fundamental phase of delegation and the extent to which authority is not delegated is called centralisation. According to Fayol ”
- d) Reliability Centred Maintenance
Answer:Reliability-centered maintenance (RCM) is a process to ensure that systems continue to do what their users require in their present operating context. It is generally used to achieve improvements in fields such as the establishment of safe minimum levels of maintenance. Successful implementation of RCM will lead to increase in
- 2. Optimizing Maintenance at XYZ Electricals
XYZ Electricals is one of the leading manufacturers of electrical utilities. The organisation is well known for delivering quality products to consumers. It has adopted
A preventive maintenance (PM) approach for the maintenance of its machines and equipment. However, in the last few months, the organisation has observed an increase in:
- Maintenance costs
- Facility downtime
- Frequent failures of components
After thorough analysis, it has been found that the main cause behind all the problems is the excessive use of preventive maintenance. The organisation also realized that it must adopt a maintenance process that maintains a balance between the requirements and resources of maintenance.
Therefore, XYZ decided to implement maintenance optimization procedures in the plant. Various optimization techniques were developed to convert traditional preventive maintenance into a cost – effective program. These techniques aimed at:
- Identifying assets that affect plant operations
- Identifying assets that may benefit most from preventive maintenance
- Selecting the most appropriate preventive tasks
- Combining appropriate traditional maintenance tasks with predictivemaintenance tasks
- Implementing appropriate training methods to apply optimization techniques
After implementing maintenance optimisation techniques, the benefits that XYZ received after optimising its maintenance are:
- Reduction in maintenance costs by removing unnecessary corrective maintenance expenses
- Improvement in understanding of assets
- Application of cost – effective preventive maintenance techniques
- Better assessment of functioning of assets when they are in operation
What are the problems at XYZ Electricals? Which was adopted to overcome the problems? Assess if the solution is effective in resolving the problem.

- Maintenance costs
- 2. List the problems at XYZ
Answer:Maintenance costs, Facility downtime and Frequent failures of components. After thorough analysis, it has been found that the main cause behind all the problems is the excessive use of preventive maintenance. The organisation also realized that it must adopt a maintenance process that maintains a balance between the requirements and resources of maintenance.
Therefore, XYZ decided to implement
- 3. Write short notes on:
- a) Production philosophy
Answer:The product philosophy was the dominant marketing philosophy prior to the Industrial Revolution and continued to the 1920s. The product philosophy holds that the organization knows its product better than anyone or any organization. The company knows what will work in designing and producing the product and what will not work. For example, the company may decide to emphasize the low cost or high quality of
- b) Mean Time to Repair
Answer:Mean Time To Repair (MTTR) is a basic measure of the maintainability of repairable items. It represents the average time required to repair a failed component or device. Expressed mathematically, it is the total corrective maintenance time divided by the total number of corrective maintenance actions during a given period of time. It generally does not include lead time for parts not readily available or other Administrative or Logistic Downtime (ALDT).
- c) Maintenance documentation
Answer: Maintenance is part of the Change Management process. Creating maintainable documentation should be a major objective for all Policies, Processes, and Procedures. The ease or difficulty of maintenance is dependent upon the foundation established during the Planning phase. With age, the quality of the Policies, Processes, and Procedures will lessen, if the Plan, Build, and Change phases are not properly performed.
- d) Online or permanent condition monitoring
Answer:Condition monitoring (or, colloquially, CM) is the process of monitoring a parameter of condition in machinery (vibration, temperature etc.), in order to identify a significant change which is indicative of a developing fault. It is a major component of predictive maintenance. The use of conditional monitoring allows maintenance
- 4. Which are the common tasks performed in maintenance management?
Answer:Most Preventive Maintenance (PM) programs were set up many years ago. Each department in a plant set up their own program in isolation from each other. As an example, a plant set up a PM program covering mechanical equipment, then another program was set up for electrical equipment and another to cover automation and control system. A lubricant vendor then added lubrication routes and on top of this other PM activities such as Vibration Analysis and Operator Inspections was added in addition to all
- 5. What are the benefits and issues related to predictive maintenance?
Answer:While many companies are perfectly satisfied with the performance of their outsourced predictive maintenance (PdM) programs, some do not get the desired results for the time and money expended. Others recognize that they have a pool of in-house talent that could do the job given enough time and training, or are facing budget cuts and pressures that force limiting, reducing or defunding PdM contracts.Vibration analysis is one of the most commonly used predictive maintenance technologies in industry.
- 6. Write short notes on
- a) Structure of maintenance budget
Answer:In Former Budgeting, the budget structure represents all the funds centers and commitment items in hierarchical form for each fund. The budget structure is year-dependent and is therefore valid up until the time it has to be redefined due to new requirements. You define an individual budget structure that is year-independent for each fund if you are using overall values for this fund. By using posting objects you specify which BS elements can be posted. The standard setting for Funds Management supports postings of actual
- b) Role of maintenance auditor
Answer: Audit is the process of checking accounting entries as per norms and guideline by the accounting professionals. The Companies Act,1956 provides for compulsory appointment of an independent person as the ‘auditor’ of the company whose responsibility is to examine the affairs of the company and to report it to the
- c) Codification of spare parts
Answer:Codification / cataloguing is basically an identification system for each item of the inventory. Normally, it is the custodian who does the codification for the items he keeps in his inventory. However, in firms of substantial sizes where good number of items are received on regular basis , codification is usually done by a team
- d) Types of maintenance benchmarking
Answer:Benchmarking is the process through which a company measures its products, services, and practices against its toughest competitors, or those companies recognized as leaders in its industry. Benchmarking is one of a manager’s best tools for determining whether the company is performing particular functions and activities efficiently, whether its costs are in line with those of competitors, and whether its internal activities and business processes need improvement. The idea behind benchmarking is to measure internal processes
