摘要
To solve the problem of a supplier＇s failure to deliver thus impacting supply chain system performance in the supply chain operating process, a model of supplier selection and order splitting in the context of a multiple sourcing setting is proposed. First, by the analysis of the elements of expected total costs of the buyer firm, namely, expected loss costs, resilience effort costs, supplier maintenance costs, and cycle purchase costs, the expected total costs function is obtained. And then, the effects of supplier characters on the supplier selection and order splitting decisionmaking are investigated by numerical examples. The results show that the maximum delivery capacity, the probability of failure to deliver and the resilience parameters are crucial elements in determining which suppliers should be selected and how to do order splitting between suppliers. Finally, current analyses focus only on the expected total costs of the buyer firm but ignore the suppliers＇ costs： thus, it is more interesting to examine the supplier decisions from both parties＇ points of view.
为了解决供应链运作流程中供应商交付失败风险影响供应链绩效问题,提出了多源采购环境下供应商选择和批量分解模型.首先阐述了供应商具有容量限制和弹性能力情形下,买方期望总成本包括期望损失成本、弹性努力成本、供应商维持成本和周期采购成本,并给出了相应的数学描述.其次研究了供应商特征对供应商选择和批量分解决策的影响,给出了相应的数值仿真.结果显示,供应商最大交付能力、交付失败概率和弹性能力是影响决策的关键因素.最后指出当前研究焦点仅是买方期望总成而本而忽略了供应商成本,应该综合考虑供应链系统双方成本.
