It is applicable to tangi-ble, physical assets owned by an organization as well as third-party assets which the organization is responsible to maintain. It is the key to adoption of Reliability Centered Maintenance (RCM), the optimum maintenance strategy mix, consisting of a fine balance between the following maintenance practices:1. Reactive Maintenance is a Run to Failure (RTF) approach that is appropriate for equipment and components whose failure does not have signifi-cant effect on the production output or safety of the manufacturing plant.2. Preventive Maintenance is a proactive approach based on time intervals and usage of the machine. It is derived from the OEM (Original Equipment Manufacturer) rec-ommendations, maintenance history and craft knowledge. It is appropriate for equipment and components with known failure patterns.3. Predictive Maintenance is a proactive approach based on predictive testing and inspection of the machine. It in-volves continuous or periodic monitoring of performance and condition of the machines and is appropriate for equipment and components known to have intermittent or random failures.EAM can enable continuous improvement in the main-tenance strategy by providing a platform for pursuing tech-niques such as Age Exploration, Failure Modes and Effects Analysis (FMEA), and Root Cause Analysis (RCA).Successful implementation of EAM can result into more effective and efficient maintenance practices and can contribute to improvement in the different constituents of OEE.1. Availability: EAM can be a major contributor in im-proving availability and utilization of machines through reduction in downtime losses related to factors such as the following:· Unplanned maintenance· Breakdowns· Component failures· Tooling damagePlanned maintenance can pre-empt failures by replacing or servicing components through scheduled maintenance activities. Faster response to maintenance requirements and improvement in maintainability of complex machinery and equipment can lead to increase in Mean Time between Failures (MTBF) and reduction in Mean Time to Repair (MTTR).2. Performance: EAM can enhance performance of machines through reduction in speed losses related to factors such as the following:· Component jams· Product flow stoppage· Equipment age· Tooling wear· Involuntary machine resetsProactive maintenance can minimize the time gap between point of initial degradation of the condition or performance of the machine, and its detection. It can increase the output of the machine, improve its energy efficiency.3. Quality: EAM can improve the yield of machines through reduction in quality losses related to factors such as the following:· Tolerance adjustments· Damage· Rejects· ReworkThe concepts of EAM, with adequate weightage to Predictive Testing and Inspection, are especially significant in demanding scenarios such as the following:· Varied product-mix produced in the same plant· Frequent line change-overs in production· Harsh ambient conditions· Plants operating in multiple shifts in a day· Tight customer delivery schedules and contractual penalties· High safety requirements in operations· Equipment with complex maintenance requirementsIn the present cost conscious environment, manufacturing plants strive to achieve most effective utilization of available resources. Effective implementation of the principles of EAM ­ the key to enhanced asset reliability, safety and efficiency ­ can lead to improvement in availability, performance and quality of output from machines, resulting into enhancement of OEE.
