Integrative Model And Optimization For Supply Chains

Nowadays, many companies run in this manner: it has specialized assembly factory and spare-part production branch factories; the assembly factory products according to the company plan and carries on local manufacture resources matching; the spare-part production branch factories' production tasks issue by the assembly factory. Under present market, there is mass production and also customization production. How to construct Agile manufacturing organization model and utilize territorial manufacturing resources is very important to improve company's agility and reduce product's cost.This paper is precisely a situation as the description above. It contains a stock room, several spare-part production branch factories, a assembly factory, a final product storage and several distribution centers. The paper analyses the cost structure of every part and gives its integrative model. The aim of this model is cost minimization under certain service level. It establishes an algorithm of PSO for this kind of problem. Finally, gives the result of the example.
