Outcomes
The results of the project included:
- Gap analysis / validation of OEM maintenance recommendations based on operational data
- Identified Poor Performers and recommended changes to the approach / periodicity of maintenance
- Increased capability readiness (Operational Availability) of the platform
- Reduced sustainment costs for the platform
- Recommendations for design improvements
- A knowledge base of failures and maintenance actions that the Contractor can reuse across the life of the platform / contract
- A means of validating and communicating their analysis to the customer
- Analysis solution to model the impact of mission profile / operating environment on maintenance costs
Process
The Contractor analysed the maintenance records for the platform to identify components that were failing more frequently than expected, and used MADE to:
- Analysis of maintenance data to identify Poor Performing (PP) components / systems
- Identify potential changes to the approach / periodicity of maintenance for PP components
- Trade studies to increase capability readiness (Operational Availability) of the platform
- Analysis solution to model the impact of mission profile / operating environment on maintenance costs
- Calculate potential reduction in sustainment costs for the platform (Maintenance Costs)
- Technical / economic validation of recommendations for design improvements
- Create a knowledge base of failures and associated maintenance actions that the Contractor can reuse across the life of the platform / contract
- A means of validating and communicating their analysis to the customer
