Modeling and simulation of two levels spare parts optimization based on GA

Aim at the unreasonable deploying of spare parts in equipment support,an optimizing arithmetic is put forward based on simulation and genetic algorithm.The model of equipments operational availability is built by simulation and optimization is realized using genetic algorithm.Operational availability of equipment can be maximized using this arithmetic while meets the limitation of spare parts cost.The process is given using this arithmetic,and the efficiency is validated through an example.
