Process Interaction Simulation Research of Adapting to Corrective Maintenance

Abstract

Corrective maintenance process simulation is one of the most important methods for equipment supportability analysis, and corrective maintenance process simulation has a positive effect on analyzing and evaluating the unavailable time which is induced by the maintenance. Discrete event simulation is one of the most effective tools to analysis corrective maintenance process nowadays. Process Interaction method (PIM) whose modelling idea is the same as human’s thinking way of natural is one of the discrete event simulation methods, and PIM is easy to be realized in the current Object-Oriented development environment, so PIM is chosen as the main algorithm used to achieve corrective maintenance process simulation. In this paper, detailed design of corrective maintenance process simulation software is achieved by using PIM. All the process class libraries and the relevant entity class libraries indispensable in simulation model are defined, and at the same time these process class libraries and entity class libraries are developed. The staple principle based on PIM about how to impel the simulation clock is illustrated. The time distribution class which is used to calculate the time of random events is achieved. At last, a simulation case is given to verify the correctness of the simulation algorithm achieved in this paper. The methodology proposed in this paper provides a new way for the implementation of the corrective maintenance process simulation, and this methodology can be more easily extended to support the concurrently maintenance activities simulation.
