Research on Joint Optimization of Level of Repair Analysis and Spare Parts Stocks

Abstract:

According to the real background of repair and supply of spare parts, aims to reasonably plan that how to and where to repair the failure parts, where to deploy the repair resources and develop the initial spares configuration program such that the availability target of equipment is achieved with the lowest investment cost, the joint optimization model for level of repair analysis (LORA) and spare parts stocks is established consisting of variable cost and fixed cost that produced in maintenance as well as the equipment availability, and a new joint optimization method for the model is proposed combined Invasive Weed optimization (IWO) and margin analysis, then the optimization is realized. In a given example, the optimization result is gotten, through which the validity of the model and method is proved.
