1 CHALLENGES IN MAINTENANCE FUNCTIONS
MECH. JOBS RELATING TO MACHINERY AND EQUIPMENT, AND SYSTEMS TOWARDS BETTER PRODUCTIVITY, HIGHER PRODUCTION LEVELS, CAPACITY UTILIZATION, EFFICIENT CAPITAL EMPLOYMENT AND REDUCED LOSSES ELECTRICAL JOBS RELATING TO ALL ELECTRIC PRIME MOVERS, POWER CONTROL, PLANNING LOAD DISTRIBUTION CIVIL AND ENVIRONMENTAL JOBS RELATING TO MAINTENANCE ELECTRONIC JOBS RELATED TO SOLID STATE DEVICES AND MICROPROCESSOR CONTROL

2 EXPECTATIONS REDUCTION IN UNSCHEDULED BREAKDOWNS
ELIMINATION OF TIME SCHEDULED OVERHAULS INCREASE IN OPERATING LIFE OF THE ASSETS REDUCTION IN DOWNTIME REDUCTION IN MAINTENANCE MANPOWER REDUCTION OF SPARES INVENTORY MAXIMIZING EQUIPMENT EFFECTIVENESS

3 TOTAL PREVENTIVE MAINTENANCE
FAILURE MODE AND EFFECT ANALYSIS CRITICALITY ANALYSIS PRELIMINARY HAZARD ANALYSIS FAULT TREE ANALYSIS HAZOP STUDIES CAUSE-CONSEQUENCE-COST ANALYSIS INTEGRATING VARIOUS MAINTENANCE SYSTEMS DETEREMINING AREAS OF CONDITION MONITORING DOCUMENTATION PROCEDURES AND SYSTEMS

4 IDENTIFYING LOSSES DUE TO FAILURES AND ADJUSTMENT OF SPEEDS AND MINOR STOPPAGES
LOCATING DEFECT LOSSES HAVING PROPER LUBRICATION SYSTEM FOR ENERGY SAVINGS

5 EFFECTIVE MAINTENANCE
RESTORE SYSTEM PRODUCTIVITY IMPROVES EQUIPMENT RELIABILITY AVOID UNNECESSARY SHUTDOWNS INCREASE OF EQUIPMENT EFFICIENCY PROLONG SYSTEM LIFE IMPROVE OVERALL PLANT EFFECTIVENESS MAINTAIN PRODUCT QUALITY INCREASE PLANT PROFIT

6 NON-EFFECTIVE MAINTENANCE
INCREASED MAINTENANCE COST REDUCED SYSTEM / EQUIPMENT LIFE INDUCED / CREATED UNWANTED WASTE ADDITIONAL COST TO CLEAN THE EQUIPMENT CAN AFFECT PRODUCT QUALITY REDUCED PLANT PRODUCTIVITY DOWNGRADED SYSTEM EFFECTIVENESS DECREASED PLANT PROFIT POOR SKILL LEVEL REPITITIVE FAILURE

7 OVERALL EQUIPMENT EFFECTIVESSS
AVAILABILITY PERFORMANCE RATE QUALITY RATE MTBF , MTTR, MUT, MDT, MCT, MLDT INHERENT AVAILABILITY STEADY-STATE AVAILABILITY OPERATIONAL AVAILABILITY

8 KEY PERFORMANCE INDICATORS
INCREASE EQUIPMENT RELIABILITY NUMBER OF UNITS REJECTED BY QUALITY INSPECTION ZERO DEFECTS SIX SIGMA ZERO ACCIDENTS MAXIMIZING O.E.E.

9 MAINTENANCE KEY PERFORMANCE INDICATORS
OVERTIME WORKED AGAINST PLAN PM SCHEDULE COMPLIANCE TIME TAKEN TO ATTEND MAINTENANCE CALLS BUDGET COMPLIANCE PM BACKLOG MANHOURS CRITICAL EQUIPMENT EFFECTIVESS NUMBER OF BREAKDOWNS PRODUCTION EQUIPMENT PERFORMANCE AVAILABILITY AND RELIABILITY

10 MAINTENANCE PERFORMANCE ANALYSIS
WORK SAMPLING TECHNIQUES JOB AUDITING SWOT ANALYSIS EVALUATION BY REPORTS EVALUATION PROCESS OF PLANT ENGINEERING - BENCHMARKING

11 MANUFACTURING BASED MODEL
PLANT OUTPUT MAINTENANCE INPUTS SERVICE BASED MODELS QUALITY BASED PERFORMANCE PARAMETERS – AVAILABILITY, RELIABILITY, WAITING TIME OPERATION BASED PERFORMANCE PARAMETERS – OVERTIME, REPAIR MEAN TIME ETC.

12 MAINTENANCE PERFORMANCE MEASURE INDICATORS
QUALITY BASED INDICES AVAILABILITY EQUIPMENT RELIABILITY: MTBS, MTTF, MTTR, MTBM, FAILURE RATE EQUIPMENT MAINTAINABILITY: MTD EQUIPMENT UTILIZATION MANPOWER EFFICIENCY REACTIVE REPAIR RATIO

13 PERFORMANCE BASED INDICES
MAINTENANCE COST PER UNIT PRODUCTION MAINTENANCE COST / HOUR TOTAL PLANT MAINTENANCE PRODUCTIVITY % COST SCHEDULED MAINTENANCE % MAINTENANCE COST TO INVESTMENT

14 % SCHEDULE COMPLIANCE SCHEDULE LOADING FACTOR WRENCH TIME MAINTENANCE WORK CAPACITY INDEX

15 MAINTENANCE OPERATION AUDIT
MAINTENANCE OPERATION PROCEDURE MAINTENANCE ORGANIZATION AND COMMUNICATION PLANNING AND SCHEDULING COMPLIANCE PLANT SHUTDOWN PROCEDURE MAINTENANCE PERSONNEL COMPLIANCE TO PROCEDURE, ROLES AND RESPONSIBILITIES INVENTORY MANAGEMENT COST COMPLIANCES TO APPROVED BUDGET CONTRACTOR PERFORMANCE REGULATORY AND STATUTORY COMPLIANCES

16 MAINTENANCE PLAN AUDIT
WORK REQUESTS / ORDERS EQUIPMENT FAILURE HISTORY EQUIPMENT LIFY CYCLE PROFILE FAILURE AND ROOT CAUSE ANALYSIS EQUIPMENT MAINTENANCE PLAN/SCHEDULE COMPLIANCE MAINTENANCE IMPROVEMENT PLAN ASSET CARE MANAGEMENT

17 TECHNICAL AUDIT THERMAL AUDIT ELECTRICAL AUDIT ENERGY AUDIT
INDUSTRIAL WATER USAGE AUDIT COMPRESSED AIR AUDIT PLANT HYDRAULIC SYSTEM AUDIT PLANT CENTRALIZED LUBRICATION SYSTEM AUDIT

18 MAINTENANCE BENCHMARKING
STRATEGIC BENCHMARKING PERFORMANCE BENCHMARKING PROCESS BENCHMARKING FUNCTIONAL BENCHMARKING INTERNAL BENCHMARKING EXTERNAL BENCHMARKING INTERNATIONAL BENCHMARKING

19 MAINTENANCE COSTS FIXED AND VARIABLE COSTS
FIXED COSTS: READY TO SERVE MEN AND FACILITIES VARIABLE COSTS: COST OF MAJOR REPAIRS AND OVERHAULS, SPARES, MATERIALS AND FACILITIES DIRECT COSTS – APPARENT COSTS: BUDGETED COST AFFECTING THE CASH FLOW OF ORGN. MATERIALS, MAINTENANCE LABOR, OVERTIME, CONTRACT SERVICES, OVERHEADS ETC.

20 INDIRECT COSTS – HIDDEN COSTS
START-UP LOSSES MISSED SCHEDULES RIPPLE EFFECT ON PRODUCTION COST OF IDLING OR RUNNING AT REDUCED SPEED EXCESS INVENTORY WASTE GENERATION EMERGENCY PURCHASES EXTRA CLEAN – UP CUSTOMER COMPLAINTS REGULATORY/STATUTORY FINES LOST BUSINESS ENVIRONMENTAL CONTROLS ACCIDENTS

21 REVENUE / CAPITAL COSTS
COST COVERED BY REVENUE BUDGET ALLOCATED FOR VARIOUS NORMAL MAINTENANCE ACTIVITIES FOR A GROUP OF EQUIPMENT / SECTION / SHOP UNUTILISED BUDGET AMOUNT CANNOT BE CARRIED OVER TO NEXT YEAR

22 CAPEX – CAPITAL EXPENDITURE
COVERED BY CAPITAL BUDGET SPECIFICALLY SANCTIONED FOR SPECIFIC JOBS, EQUIPMENT – ADDITION, MODIFICATION, REPLACEMENT SCHEMES GENERALLY NOT TAKEN IN REGULAR COURSE OF MAINTENANCE NO ADJUSTMENT OF CAPITAL BUDGET PERMISSIBLE FROMMONE EQPT. TO ANOTHER OR FROM ONE JOB TO ANOTHER

23 MAINTENANCE COST COMPONENTS
READY TO SERVE CONDITION MONITORING – FACILITIES PM, PdM, CBM CORRECTIVE MAINTENANCE MAJOR REPAIR, OVERHAULS, REVAMPING MATERIALS – SPARES, CONSUMABLES, TOOLS, TACKLES DIAGNOSTIC AND MEASURING EQUIPMENT CAPTIVE SHOPS, CENTRAL SERVICES EXTERNAL AGENCIES – TESTING, AUDIT ETC. CONTRACTORS , MAINTENANCE OUTSOURCINGS TRAINING AND DEVELOPMENT

24 REGULATORY / STATUTORY EXPENDITURES
INSURANCE LIABILITES NON WORKING MAINTENANCE LABOR MAINTENANCE WORK DONE BY PRODUCTION EMPLOYEES NON CAPITAL PLANT IMPROVEMENTS

25 MAINTENANCE COST ANALYSIS
UNDERSTAND THE COSTS TO MAINTAIN EQUIPMENT IDENTIFY FAILURE MODELS IDENTIFY OPPORTUNITIES TO REDUCE COSTS VALUE Vs. COST OF SPARES INVENTORIES DEVELOP RELIABILITY MODEL DIRECTLY FROM MAINTENANCE RECORDS

26 COST CONTROL IN MAINTENANCE
KEEP BREAKDOWN COST DIFFERENT FORM PM, PdM, CBM COST-CONSCIOUS MAINTENANCE PERSONNEL MAINTENANCE PREVENTION USING COST REDUCTION TECHNIQUES – REPAIR Vs REPLACE, LIFE CYCLE COSTING WASTE REDUCTION AND WASTE RECOVERY SALVAGING OF SPARES SUB-ASSEMBLIES

27 MAINTENANCE BUDGET BUDGET IS A FORECAST OF EXPENDITURES AND REVENUES
APPROPRIATION BUDGETS: LUMPSUM AS THE MAX. AMOUNT THAT CAN BE SPENT FOR A GIVEN ITEM FIXED BUDGETS: SPECIFY ALLOWABLE AMOUNT OF COST FOR A PERIOD OF TIME FLEXIBLE BUDGET

28 PREPARATION OF MAINTENANCE BUDGET
ALLOCATE REVENUE AND EXPENSES USING TOP DOWN / BOTTOM UP PRODUCTION MAINTENANCE SCHEDULE APPROACH LABOR ALLOCATION APPROACH INTEGRATED APPROACH
