A computer implemented method predicts the operational availability of a certain, complex weapon system in the in service support phase. Formulas are used regarding
€¢ MMT (Mean Maintenance Time),
€¢ MLDT (Mean Logistic Down Time) and
€¢ MTBF (Mean Time Between Failures). The operational availability at a future point in time is calculated through the usage of reliability, maintainability and supportability parameters P1, P2, P3, P4, P5, P6 and P7, whereby
€¢ P1 is a Configuration Management performance parameter,
€¢ P2 is a Technical Events-Monitoring performance parameter,
€¢ P3 is a Supply chain performance parameter,
€¢ P4 is a Maintenance activities performance parameter,
€¢ P5 is a Technical Documentation Management performance parameter,
€¢ P6 is a Obsolescence Management performance parameter,
€¢ P7 is a Training activities performance parameter. Each performance-parameter varies over time during the in service support phase of the weapon system and is linked to the real support environment in which the weapon system has to operate,
whereby
€¢ MMT is a function of at least P4, P5 and P7,
€¢ MLDT is a function of at least P1, P3 and P6,
€¢ MTBF is a function of at least P2, P4, P5 and P7.
