  2. WWW.PPTMART.COM • It is a systematic approach to planning the maintenance activities, using decision making tools to improve the overall efficiency & effectiveness of the operating system

  3. WWW.PPTMART.COM MAINTENANCE ALTERNATIVES • Inspection (Routine) • It involves checking lubrication, vibrations, dusting, cleaning etc. • Typically done at the beginning of shift • Helps in timely detection of problems • Predictive Maintenance (Condition Monitoring) • Condition of the equipment is constantly monitored • Decision to carry out maintenance is taken based on the analysis of changes in equipment behavior

  4. WWW.PPTMART.COM • Preventive Maintenance (PM) • It includes routine inspection as well as replacement of certain components before their failure • It tends to avoid breakdown of the equipment due to ageing & wear & tear • Breakdown Maintenance (BD) • It is both expensive & undesirable • It brings down the useful life of the equipment

  5. WWW.PPTMART.COM Preventive Maintenance Vs Breakdown Maintenance Total Cost Cost of PM Cost of Maintenance Cost of BD Level of PM activity

  6. WWW.PPTMART.COM • Planned Shutdown/Major Overhauls • They are generally made once a year • It aims towards de-bottlenecking, improving working conditions by adding more capacity which preventive maintenance fails to do • Helps in timely detection of problems Equipment Replacement • It involves heavy capital outlay • Done when both preventive maintenance & breakdown maintenance proves to be expensive

  7. WWW.PPTMART.COM Cost & Operational Impact Of Maintenance Alternatives Equipment Replacement Major Overhaul Breakdown Maintenance Cost of Maintenance Predictive Maintenance Preventive Maintenance Routine Inspection Little Substantial Impact on capacity

  8. WWW.PPTMART.COM TOTAL PRODUCTIVE MAINTENANCE • TPM is an alternative approach to equipment maintenance that seeks to achieve Zero breakdowns & Zero defects • It enables continuous & rapid improvement of the manufacturing processes through the use of employee involvement & employee empowerment • It is a successful blend of preventive maintenance ideas with TQM

  9. WWW.PPTMART.COM OVERALL EQUIPMENT EFFECTIVENESS • It is used to assess the performance of TPM • OEE essentially captures six big losses that occur in an organization, resulting in reduced effectiveness of using an equipment

  10. WWW.PPTMART.COM Six Big Losses That Affect OEE EQUIPMENT SIX BIG LOSSES Operating Time (A) Downtime Losses Loading Time (B) 1. Breakdown 2. Setup & Adjustment Net Operating Time (c) Speed Losses 3. Idling & Minor Stoppage 4. Reduced Speed Valuable Operating Time (D) 5. Defect & Rework Quality Losses 6. Startup
