Supply Chain Risk Assessment Based on AHP and Fuzzy Comprehensive Assessment Mode: A Case Study of the Chemical Supply Chain

Recently, there have been frequent accidents in energy chemical industry, hence the emergency management become normalized. Risk assessment provides basis for policy makers to make decision in the cases of the uncertain information and emergency. The chemical supply chain are influenced by many risk factors. In order to make the assessment of chemical supply chain risk by combining the qualitative method with quantitative method, this paper summarizes the characteristics of the chemical supply chain, applies analytic hierarchy process (AHP) to establish risk assessment system, carries the quantitative analysis on risk factors and their weights, establishes the fuzzy comprehensive evaluation model. Analysis of examples shows that in the complicated system of a variety of risks, risk assessment model that based on the AHP can realize the assessment of the individual risk and the comprehensive risk. The validity and science of the model can be verified through comparing evaluation results with actual results.
