A computer-based method for determining an effect of operational readiness for a vehicle in a fleet of vehicles based on a component replacement simulation is described. The method includes querying, using a fleet performance optimization tool, a maintenance data database. The method also includes analyzing the data set using a power law process to predict a next component removal for each vehicle based on hours of operation for each vehicle. The method also includes determining an effect of operational readiness for the selected vehicle based on the simulation. The method further includes ranking each vehicle in the fleet of vehicles based on the operational readiness of each vehicle. The method also includes displaying, based on the ranking, the operational readiness of each vehicle on the user interface to facilitate actual replacement of at least one component on at least one of the vehicles.

Step analysis process steps within a fleet performance optimization tool

Described herein is an apparatus that includes a minimum equipment list (MEL) data module and an impact assessment module. The MEL data module determines at least one operational limitation associated with deferred maintenance on a vehicle. The impact assessment module determines an operational impact associated with the deferred maintenance based on the at least one operational limitation.

Deferred aircraft maintenance impact assessment apparatus, system, and method

A Maintenance Interval Determination and Optimization Tool (MIDOT) provides optimized maintenance schedules for performing maintenance tasks on one or more components or systems based on component survival functions and economic analysis of non-safety tasks associated with maintenance schedules. MIDOT is used for specified platforms such as aircrafts. The MIDOT filters maintenance history data, uses a statistical analysis to predict likely maintenance needs, and performs an economic analysis to optimize aircraft maintenance schedules. Specifically, the MIDOT calculates component survival probability, based on the specific usage of one or more related components within the platform and determines an optimal maintenance task interval to perform a maintenance task associated with the one or more related components.
