1. Maintenenace Performance evaluation

2. What is Maintenance Performance evaluation Analysis of current maintenance framework to assess the required potential improvements to achieve best possible Maintenance Practices

3. Need of evaluation Resources utilisation Resource requirement of manpower, equipment's Comparison of Maintenance within and to other organisations Effectiveness and Efficiency of Maintenance

4. Objectivities of evaluation Avoiding overstaffing and understaffing Setting Standards for different types of work in advance S kill of the maintenance personnel Spare part requirement Maintenance type needed for a particular equipment/system Finding out problems being faced by management

5. Benefits of Maintenance Evaluation Performance Improvement Reduction in Delay Reduction in Equipment Down Time Improvement in Preventive Maintenance

6. Benefits of Maintenance Evaluation Performance Improvement Reduction in Delay Reduction in Equipment Down Time Improvement in Preventive Maintenance

7. Types Evaluation Through Reports Done on basis of reports which are prepared at fixed time intervals Depends on Accuracy of reports Subjective Qualitative type evaluation on expertise of the subject Qualification of personannel and training Objective Qualitative Assess Maintenance costs Indiacte performance of Maintenance Personnel Recognises equipment availability Work Auditing Total time of non availability of equipment and time taken to attend the fault is analysed. Step by step progress of randomly selected job is recordeed to highlight the delays caused Enables to identify the weak points where improvements are possible and corrective actions are initiated accordingly J ob Card Analysis Gives the detail of time taken for each job element and deviation/delay from the scheduled time in starting or doing the job

8. Maintenance Performance evaluation factors Evaulation Factors Economic Backlog Effectiveness of Maintenance Planning Cost of Maintenance OEE (Overvall Equipment Efficiency) MWT ( Mean Waiting Time) MTBR( Mean Time Between Repair) MTTR( Mean Time To Repair) Plant Availability MTBF(Mean time Between Failure)

9. MTTF ( Mean Time To Failure) Measure of reliability used for non-repairable systems Represents the length of time that an item is expected to last in operation until it falls Referred to as the lifetime of any product or a device Calculated by considering number of the same kind of items over an extended period of time and seeingw what is their mean time to failure. MTTF = Total Hours of Operation Total Number of Units

10. MTTF ( Mean Time To Failure)

11. MTTR ( Mean Time To Repair) Average time required to repair failed equipment and return it to normal operating conditions. It generally does not take into account lead-time for parts. Reflects how well an organisation can repond to a problem and repair it https://www.slideshare.net/ShreyaAnand21/maintenance-performance-evaluation

12. MTTR ( Mean Time To Repair) Notification Time Diagnostic Time Fix Time Wait Time Reassembly Alignment Calibration Test Time Back to Operations

13. MTTR ( Mean Time To Repair)

14. Over-All Equipment Effectiveness Gold standard for measuring manufacturing productivity Identifies the percentage of Manufacuturing time that is truly productive Measuring OEE is a manufacturing best practice , for overcoming the underlying lossess Helps Improving Operational process.

15. Over-All Equipment Effectiveness An OEE Score of 100% means the company is following best practices , as fast as possible withno Stop Time.

16. Over-All Equipment Effectiveness

17. MTBF/MEAN TIME BETWEEN FAILURES (SHUTDOWNS) It is a measure of how reliable component is. For most components , the measure is typically in thousands or even tens of thousands of hours between failures. MTBF figure can be developed as the result of intensive testing, based on actual product experience

18. MTBF/MEAN TIME BETWEEN FAILURES (SHUTDOWNS)

19. MWT/ MEAN WAITING TIME It is a application of probabilistic models to measure waiting time problems , to compare two or more different service patterns

20. FAILURE RATE It is the anticipated number of times that an item fails in a specified period of time. Calculated value-provides a measure of relaibility for a product. Number of failures/Total Operating Hrs Expressed as failures per million hours/failures per billion hours

21. OTHER PARAMETERS

22. OTHER PARAMETERS Plant Availability = Total Available Hours- Total Down Time Total Available Hours Backlog- Estimated man hrs for all jobs/Actual Hrs available to schedule ---------------------------------------------------

23. MAINTENANCE PERFORMANCE INDICES These are criteria to evaluate the effectiveness of maintenance called MEI ( Maintenance Effectiveness Index) Quantitative based fixed criteria which consider a defined level of maintenance functions and achieved objective Helps to assess the level of effectiveness of the maintenance Vary at different levels of maintenance department and industry

24. KEY PERFORMANCE INDIC ATORS KPIs Indicate What maintenance is doing What it is achieveing for the business What more it can do to improve operational performance

25. STATISTICAL ANALYSIS OF PERFORMANCE Avilable information (past) is analysed for creating indices for maintenance evaluation. Data considered=6 months (more) Helps find out time lost in undesired activities

26. COST OF MAINTENANCE EVALUATION Cost of personnel employed for the evaluation Idle time cost of the maintenance workers for answering the queries of the evaluation team The increased recurring maintenance costs due to revision of the wage structure on account of the introduction of the new job evaluations. Cost of Maintaining the job evaluation team.

27. The feasibility of the Maintenance evaluation method was demonstrated through an actual scenario, to help managers make decisions objectively and disntinguish the advantages and disadvantages of the Maintenance stratgy
