1、北京交通大学博士学位论文供应链系统的复杂性与评价方法研究姓名：杜志平申请学位级别：博士专业：系统工程指导教师：张仲义20071201北京交通大学博士学位论文一随机DEA模型。(6)对论文研究工作进行总结，提出有待进一步完善和深入研究的问题。本学位论文的重点，即创新之处体现在四个方面：一是从熵的角度给出供应链不确定性的量化方法，将供应链的不确定性分成结构、运作和环境分别给出相应的计算方法。二是将可靠性概念引入供应链研究，给出供应链可靠性的概念和基于连通和最小路径集下的计算方法，并进一步将供应链的可靠性分解成结构可靠性和运作可靠性，给出相应的计算方法。三是
2、首次提出从不确定性、可靠性、经济性和发展潜能四个方面建立基于复杂性的供应链复合评价的概念，并给出复合评价指标体系。四是首次将熵——DEA模型、随机——DEA模型和DEA模型进行集成，给出供应链复合评价模型。关键词：供应链、复杂性、评价、数据包络分析、熵^BSTRACTAbstractManyexistingresearchesarcaboutSupplyChain(SC)，andmostofthemfocusonthemanagement，operationandevaluationofstableSC．However,SCisanartificial
