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.
