具有风险的供应商选择中延迟成本的计算算法The Calculation and Algorithms of Delay Cost in Supplier Selection with Risks

摘要(Abstract)：
针对供应商选择问题中面临的不确定情况,以及采购过程中可能遇到随机延迟的现状,应用连续型随机变量离散化的方法,将不同供应商延迟周期的组合问题转化为所有供应商总的延迟周期的组合问题,从而减少了组合的数量.利用卷积公式证明了参数相同和参数互不相同两种情形下,m个服从指数分布的随机变量的求和密度函数,并且利用条件期望估计了每种情景下的延迟成本.最后,给出了所有供应商总延迟周期在不同情形下的延迟成本的算法。
