一种基于AHP-未确知模糊理论的云计算环境下供应链信息协同风险评估

A Risk Assessment Method of Supply Chain Information Coordination Based on AHP-Unascertained Fuzzy Theory under Cloud Computing

针对云计算环境下供应链信息协同风险具有动态性以及评价指标模糊性和不确定性的特点,提出基于AHP-未确知模糊理论的供应链信息协同风险评估模型,构建了云计算环境下供应链信息协同风险评价指标体系,并应用AHP法确定各个风险因素的权值,结合评分专家的可信度并用未确知理论得到模糊关系矩阵以提高模糊综合评判法的精度,最后通过实例证实了该评估模型的合理性和可行性.

An eeffective information coordination risk evaluation is necessary for ensuring the smooth operation of supply chain coordination,assisting node enterprise to make the correct decision,and avoiding risks and solving problems.Under cloud computing environment,supply chain information coordination risk is dynamic,and evaluation index is vague and uncertain.Therefore,in the study,based on AHP-unascertained fuzzy theory,the risk evaluation model of supply chain information coordination was proposed.Firstly,according to the construction of supply chain information coordination risk evaluation index system under cloud computing,AHP was used to determine the weights of each risk factors; Secondly,combined with the experts credibility,the unascertained theory was used to obtain fuzzy relation matrix,the accuracy of fuzzy comprehensive evaluation method was improved; Finally,the experimental example was used to prove the reasonability and feasibility of the evaluation method.
