TPM HistoryDr. Deming1900-19931951PMNippon DensoPM in 1960Nippon Denso TPM AwardCopyright 20103

Total Productive Maintenance Promote the collaboration between all departments to focus on thedurability of equipmentCopyright 20104

Definition Total: Total employee involvement Productive: Eliminate or minimize breakdown duringproduction Maintenance: Complete a preventive maintenanceprogramCopyright 20105

Benefits of TPM Improves Teamwork Improves Equipment availability Reduces costCopyright 20106

Roles of TPM To target the major causes of poor performance (OEE ) Involve operators in the routine maintenance of their equipment Improve maintenance efficiency Improving skills and knowledge To collaborate in partnership while having a common goalCopyright 20107

Applying TPM Create a cross functional team–––––D-DefineM-MeasureA- AnalyzeI- ImproveC- ControlCopyright 2010 Luis Armendariz8

Define DMAICD: Define the equipment, objectives,success indicators, customers, costCopyright 2010 Luis Armendariz9

Applying TPM “Where to Start ?” Start with an equipment pilot1.Choose the right machine2.Choose the right person3.Choose the good timeCopyright 201020

Justice to Root Cause Analysis “RCA”A systematic method that:Investigates as incident, attempts to understand the underlying causes andgenerates corrective actions to prevent and mitigate incidentsCommon Recommendations: Training Procedure Revision Repair or Replacement of broken equipment Restart the system Fix and go !Copyright 201022

COST of Non TPM “ 30 Million Refinery Glitch Stalls Fuel Users – No Petrol for 2 Weeks” “Liquefied Natural Gas Project Back On Track after Production Train Repairs 300 Million Lost” “Refuelling Problems Delay 250 Million Terminal Operation – Jet Fuel PipesContaminated” “330 Hospital Patients Suffer Cold Winter Showers for Two Days – Risk of Spreading Infection”More than 4 million barrels of crude oil spewed into the seas off the U.S. Gulfcoast & 1.2 billion dollars in claimsCopyright 201026

TPM Implementation Challenges OEE measures RCA Leadership (Who Should Lead TPM ?) Employee training, development & compensation Employee Turn Over Collaboration Accountability Defined Responsibilities Spare parts and tools inventory mgt. 5S Visualize Standard Work and Maintenance Instructions Share best practicesCopyright 201027
