从铁路建设项目物资设备采购角度出发,对采购风险进行系统分析并做出科学度量是建立科学、完善的铁路物资设备采购风险管理的基础。从产品风险和供应商风险两个视角对铁路建设项目物资设备采购风险进行研究。在具体的采购风险度量中,采用了以Vague集理论为基础的模糊物元分析方法,并以信息论中熵权计算方式确定不同指标权重,从而考察各方案与理想方案及负理想方案之间的距离,以此表示出产品风险系数及供应商风险系数。
From the perspective of procurement of materials and equipment for railway construction projects, systematic analysis of procurement risks and making scientific measurements are the basis for establishing a scientific and complete procurement risk management for railway material and equipment. From the product risk and supplier risk two perspectives on the railway construction project material and equipment procurement risk research. In the specific measurement of procurement risk, the method of fuzzy matter-element analysis based on Vague set theory is adopted, and the weight of different indicators is determined by the way of entropy weight in information theory, so as to examine the relationship between each option and the ideal solution and the negative ideal solution Distance, in order to show product risk factor and supplier risk factor.
