需求不确定的汽车零部件集成供应网络优化研究

Design of Integrated Supply Network of Auto Parts under Uncertain Demand

随着经济快速发展,汽车保有量逐年增加,报废车辆对环境和资源造成了双重压力。文章通过构建汽车零部件产品的闭环供应网络,实现循环经济,缓解压力。该网络综合考虑多个运行周期、不同周期内产品需求数量的不确定性、实体容量限制等,以运行总成本最小为目标函数,构建整数线性规划数学模型,并通过LINGO软件进行求解验证,为汽车行业循环经济的发展提供一定的借鉴。

With the rapid development of economy and explosive growth of car ownership,the scrap vehicles have caused the dual pressures in environment and resources.In the paper,the closed loop supply network of automobile parts is constructed to realize the circular economy and relieve the pressures.The comprehensive considerations are taken in the network concerning the number of multiple operation cycles,demand uncertainty in different periods,and entity capacity constraints.The aim of the model is to minimize the total cost and construct an integer linear programming model,which are solved and verified by Lingo.The conclusion can provide reference for the development of circular economy in automobile industry.
