摘　　要：考虑到实际中的生产过程大多数都是多阶段的生产过程,而传统的数据包络分析模型只能对单阶段的生产过程进行评价.传统的数据包络分析模型在应用中的局限性很大.本文是在传统数据包络分析模型的基础上,通过引入离散的时间变量来建立对整个多阶段生产过程进行评价的数据包络分析模型.In consideration of the actual production process consisting of several stages, while the traditional DEA model can only been applied on those decision making units that have only one single stage, so the traditional DEA model has many limits in most appliance. Based on the traditional DEA models, this paper establishes the time-oriented DEA model. The time- oriented DEA model can evaluate the relative efficiency of the decision making units that have several stages in sense of the whole production process.
