Study on optimizing of two-echelon spares storage based on GA

The paper introduces how to use GA to Optimize Two-echelon Inventory of Maintenance Spare Parts. Firstly, it analyzes the structure, factors, mathematical model and parameter of two-echelon maintenance spare parts support system. Secondly, it discusses programming methods of coding and GA operators. Thirdly, it provides a example with concrete input data and result based on GA that is given in this paper, and gives the programming thought base on Matlab GA toolbox.

I Introduction

MAINTENANCE support system is a important element for quality of maintenance serving, and spares is a key element of maintenance support system. Spares storage level is a important index for evaluating maintenance support grade. Much less spares storage would not be filled of the requirement of supporting, but much more spares storage would be wasted of outlay. So, it's a very important thing to forecasting and optimizing spares' storage.
