ATO通用策略在费用分担模型的应用

以由一个零部件供应商和一个产品组装制造商组成的ATO两级供应链为对象,研究零部件供应商和组装产品制造商共同投资缩短零部件供应提前期以缩短产品交货期的相关模型.在此情况下,主要从成品组装制造商的角度建立相关成本模型,以总运作成本最小化为目标求解零配件供应提前期和订货批量两个决策变量,通过比较三种产品结构的结果考察了通用件和制造商费用分担份额对产品交货提前期及总运作成本的影响.算例分析表明,采用通用件有助于减少制造商的总运作成本,并在制造商费用分担额度较大时,有利于缩短产品交货提前期.

Cost Sharing Model for Delivery Time Reduction with Component Commonality in ATO Supply Chain

A cost sharing model in ATO supply chain was structured,with the varieties of the component's supply leadtime and lot sizes.The objective was to optimize the product assembly manufacturer's operation cost.The impacts of component commonality and fraction of investment on the product delivery time and total operational cost was discussed.The result of numerical examples demonstrates that the total operation cost can be largely reduced by using component commonality strategy.If the product manufacturer chooses a relatively large fraction of investment,the product delivery time can also be reduced by using component commonality.
