摘要
针对供应链系统风险因素的特征,建立了供应链系统风险评估的指标体系,提出一种基于可拓物元模型的供应链系统风险评估方法。该方法将待评估供应链系统风险、评价指标及其特征值作为物元,并建立风险关联函数,通过计算综合风险关联度得到供应链系统风险的大小。最后,通过实例对该模型和算法进行了验证分析,结果表明,该方法有效地解决了评估因素指标的非定量性、模糊性及其不相容性问题,并能够有效地保证风险评估的质量和效率。
According to the characteristics of supply chain system risks,an assessment index system of supply chain system risks was built.Meanwhile,an assessment method of supply chain system risk based on extension matter element model was put forward in this paper.The supply chain system risks to be assessed,assessment index and its characteristic value were taken as matter elements.The risk relational function was construction,and the supply chain system risk was evaluated by calculating the comprehensive relational degree.Finally,analysis of this method was performed by an example,which results show that this method can effectively solve the non-quantification,fuzziness and incompatibility problems of the evaluation index.The method can effectively ensure quality and efficiency of the risk evaluation.
