Maintanance management

  1. 1. Maintenance Management
  2. 2. Introduction Modern maintenance management is not to repair broken equipment rapidly. Modern maintenance management is to keep the equipment running at high capacity and produce quality products at lowest cost possible.
  3. 3. Meaning of Maintenance & Maintenance Management  Maintenance is defined as “any action that restores failed units to an operational condition or retains non- failed units in an operational state”.  Maintenance Management is concerned with the direction and organization of resources in order to control the availability and performance of industrial plant to some specific level.
  4. 4. Objective of Maintenance  Minimizing the loss of productive time because of equipment failure.  Minimizing the repair time and repair cost.  To keep all productive assets in good working condition.  Efficient uses of maintenance personnel and equipment.  To improve the quality of the products and to improve productivity.  To maximize efficiency and economic in production through optimum use of facilities.
  5. 5. Importance of Maintenance Management  Dependability of services  Quality Assurance  Help in not Loosing Market Share  Cost Context Induction  Organizations depend upon Equipment
  6. 6. Types Of Maintenance  There are 4 models are available- 1. Breakdown/Corrective Maintenance 2. Preventive Maintenance 3. Predictive Maintenance/Condition Maintenance
  7. 7. Types Of Maintenance  Preventive Maintenance: Periodic inspection is carried out to anticipate breakdowns and to prevent them before they occur, instead of allowing the breakdown to happen and then to take action.  Breakdown Maintenance: It occurs, when there is a work stoppage because of machine breakdown. In this sense maintenance become repair work. Repair are made after the equipment is out of order.
  8. 8. Types of Maintenance Total Cost Breakdown Maintenance Cost Preventive Maintenance Cost Cost Level of Maintenance Activity
  9. 9. Total Productivity Maintenance  TPM is a way of organizing maintenance to support productivity & quality through increased equipment efficiency and to reduce costs.  TPM concept means that all employees work in small groups to maximize the improvement of equipment efficiency.  Operators are working independently with all maintenance activities of their own equipment and have also the total responsibility of operation and maintenance.
  10. 10. Objective of TPM  Avoid wastage in a quickly changing economical environment.  Producing goods without reducing product quality  Reduce Cost  Produce a low batch quantity at a earliest possible time.  Goods send to the customers must be non-defective.
  11. 11. Need For Replacement There are two basic reason for replacement of machine:  First and foremost is safety.  Another legitimate reason for replacing equipment is that it is no longer cost effective to maintain.  The machine are to be periodically replaced.  The replacement study can be classified into two categories: • Deterministic types of items that deteriorate with time[Replacement due to gradual failure] • Simple probabilistic model for items which fail completely[Replacement due to sudden failure]
  12. 12. Simple Probability Model  Electronic items like transistors, resistors, tube lights bulbs, etc. will fail all of sudden.  Failure of these causes complete breakdown of the system.  Few policies are considered for these kind of replacements. I. Individual Replacement Policy II. Group Replacement Policy
  13. 13. Replacement Policies  Individual Replacement Policy If a particular light is beyond repairs, then it is replaced. This kind of policy of replacement is called as ‘replacement of items as-and-when they fail’ or ‘Individual Replacement’.  Group Replacement Policy There are certain items which do not deteriorate but fail completely after certain amount of use. These kinds of failures are analyzed by the method called as group replacement theory. Here, large numbers of items are failing at their average life expectancy.
  14. 14. Reliability Performance The ability of an item, under stated Conditions of use, to perform a required Function under stated conditions for a stated period of time.
  15. 15. Computerized Maintenance Management System(CMMS)  A CMMS software package maintains a computer database of information about an organization’s maintenance operations, i.e. CMMIS – computerized maintenance management information system.  This information is intended to help maintenance workers do their jobs more effectively (for example, determining which machines require maintenance and which storerooms contain the spare parts they need).  To help management make informed decisions (for example, calculating the cost of machine breakdown repair versus preventive maintenance for each machine, possibly leading to better allocation of resources).  CMMS data may also be used to verify regulatory compliance.
