Research on Simulation Modeling and Optimization of Maintenance and Support Based on CPN at the Grass-roots Level

The development and application of high-tech equipments, from equipment design, general equipment quality characteristics, aircraft information design to maintenance strategy and supporting resources, have a significant impact on maintenance and support. The improvement of maintenance and support strategy and capability in grass-roots level is an urgent problem to be solved in the battle department. This paper focuses on the maintenance and support simulation modeling of grass-roots level and task division optimization problem, first of all, using the modular modeling ideas to draw the basic-level maintenance and support scene operation flow chart, constructs the basic-level maintenance and support model parameters system, and then establishes the maintenance and support simulation model of grass-roots level based on the CPN. And the optimal method of task division based on genetic algorithm is explored. In order to optimize the process of maintenance and support in the grass-roots level, regard sortie generation rate and operational availability as objective functions. The optimal results can provide the effective theoretical support for the aviation combat department to enhance the operational supporting ability.
