Outcomes
The results of the project included:
- Analysis solution to model the impact of mission profile / operating environment on maintenance costs
- Identified potential poor performers in the system based on assumed system reliability
- Proposed maintenance actions given a system reliability
- Validation of sustainment approach
- A knowledge base of failures and maintenance actions that the OEM can reuse across the life of the platform / contract
Process
The OEM analysed the maintenance records for the platform to identify components that were failing more frequently than expected, and used MADE to:
- Generate a MADE model of the CRV platform
- Define the expected Mission Profiles / Operating Environments
- Calculate the expected reliability of the systems
- Identify the maintenance requirements for the design configuration
- Conduct trade studies to optimize Readiness and Affordability of the CRV platform based on the impact of configuration / mission profile / operating environment on maintenance costs
- Conduct technical validation for the recommended maintenance approach
- Calculate expected maintenance costs of the platform
- Maintain a knowledge base of failures and associated maintenance actions that can be reused across the life of the platform / contract
Outputs
MADE was used to generate the following deliverables:
Charting the failures
Graphically represents failure contributors
Reliability Analysis
Sets a reliability for the system to analyse MTTF
Reliability Block Diagrams
Reliability Block Diagrams of the systems (to identify PP components)
FMEA / FMECA
FMEA report for the systems (automatically) generated from the MADE model)
Maintenance Cost Estimate
Provides sustainment parameters to conduct sustainment analysis
