Corrective maintenance process simulation algorithm research based on process interaction

Corrective maintenance process simulation is one of the most important methods to equipment supportability analysis, and it can analyze and evaluate the unavailable time induced by failure to equipment system. In this article, specific design of corrective maintenance process simulation software using Process Interaction method (PIM) is achieved. Relevant processes and entities which are in corrective maintenance process simulation model are defined, and the functions of the processes and entities are analyzed. Basic principle based on PIM about how to impel the simulation clock is illustrated. Corrective maintenance process classes are achieved. Static structure classes diagram and maintenance activities diagram within interacting processes are established. The proposed methodology is a guidance for corrective maintenance activities simulation platform development, and it can be more easily extended to support the concurrently maintenance activities simulation.
