基于并联输入阶段的合作DEA方法在外购或自制决策中的应用

Applying the Parallel Input Stages of DEA Cooperative Model to Evaluate the Make or Buy Decision

首先在两阶段合作DEA模型的基础上构建一个基于并联输入阶段合作DEA的综合性的供应链绩效评价模型,应用在当企业以自制与外购的混合决策的比较。通过关于泰国龙眼干加工生产行业的案例,来探讨农民合作社加工企业的采购环节与整体供应链绩效的评价过程,这种方法使我们能够把自制或外购决策研究中,发展到自制与外购混合研究。模型不只应用基准了某企业在每个环节及整个供应链的绩效比较,而且也可以对所考察的企业中,提出最适合某个企业的自产或外购的战略。
