Automated design for maintainability

A set of computerized techniques which can be used during the system design process to predict and utilize maintainability system parameters associated with repair times, manpower requirements, availability, and false alarm rates, are examined. Included is a description of a software module which applies the statistical techniques set out in MIL-HDBK-472 Procedure V. The module provides a standard database of the elemental maintenance task times set out in RADC-TR-84-165 and the ability to create user-specific elemental task databases which can be used to compile knowledge of maintenance times gained through experience with similar systems already in operation. Hierarchical modeling techniques make it possible for maintainability parameters to be calculated for the entire system, or any level of subsystem desired, without reentering failure mode and repair data
