Maintenance, by definition are the actions necessary for retaining equipment in, or restoring it to, a serviceable condition.The preventive maintenance strategies that are deployed will have a major impact on the resulting performance, where the completeness, accuracy and consistency will ensure that implementation and uptake is effective. Overcome the challenges with your preventive maintenance planning process, and deliver consistency, justification, efficiency, and effectiveness of the development and deployment of strategies.
The Maintainability tasks along the phases of life cycle and according to the requirements of the customer needs as follows:
1. Design for Maintainability,
2. Maintainability Predictions
3. The demonstration of the Maintainability requirements
4. Preventive, Corrective and Servicing Maintenance
5. Reliability Centered Maintenance (RCM)
Establishing Quantitative maintainability / testability metrics that include:
• Mean Time to Repair / Replace / Exchange
• Maximum Time to Repair / Replace /Exchange
• Equipment Repair Time
• Maintenance Man-Hour
• Repair Rates
• Maintenance Rates
Maintainability and Availability
Availability
Availability as defined is the probability that a system/product will be in a functioning
Condition when required. Availability is generally relevant to repairable systems/products. Availability is also applicable to services. The availability of a system/product may be increased by improving its reliability, testability or maintainability performances.
The following activities will be performed to establish the Availability factor in RAMS,
Availability Study
• Define Customer Need
• Analyze existing data and elements
• Define Recommendations
• Validate Requirements and Assumptions
• Define Strategy
• Allocate Requirements
