Determine optimal maintenance strategy
Every company is exposed to risks. Risks can affect different business values, such as financial, quality, environment and safety. Companies determine risk mitigating measures for these risks. Maintenance activities are mitigating measures. Three different maintenance strategies are possible: failure dependent (corrective repair when the function is no longer available), usage dependent (after a fixed usage period or time maintenance is executed) and condition based (carry out maintenance when a certain limit is exceeded, where the function is still being fulfilled).
Because resources are scarce, for the determination of the maintenance strategy it is needed to determine which activities have the highest added value. MaintenancePlanner helps in carrying out such an analysis. It calculates the total cost of ownership (TCO) across all business values, so you can easily see which maintenance strategy is most attractive.
Een impression of the graphs can be shown above.
Benefits of MaintenancePlanner

- Failure models and residual failure models for different maintenance strategies:
- Corrective maintenance
- Preventive maintenance
- Condition-based maintenance
- Combination of periodic and corrective
- Combination of regular and preventive replacement
- Combination of condition-based and corrective
- Combination of condition-based and preventive replacement
- Calculating Total Cost of Ownership per period for different maintenance strategies
- Charts with sensitivity analysis for different strategies
- Graphs with regret analysis for the various strategies
- Graphs as mentioned above for Best guess, Best case, Worst case. The probability of each scenario can be entered
