Fuzzy comprehensive evaluation of imported alcohol safety risk based on AHP and risk matrix

Abstract

ObjectiveTo improve the prediction and early warning ability of the customs supervision department on the safety risk of imported alcohol， ensure food safety in China， and accelerate the efficiency of customs clearance， a fuzzy comprehensive evaluation model of imported alcohol safety risk based on analytic hierarchy process and risk matrix was constructed.MethodsBased on the expert investigation results， the weight of each index was determined using the analytic hierarchy process， and the fuzzy membership matrices were obtained using the risk matrix. Subsequently， the risk value of each index was obtained using a fuzzy comprehensive algorithm. Simultaneously， a dynamic adjustment factor was introduced to finally realize the risk grade evaluation of specific batches of imported alcohol.ResultsThe safety risk level of imported alcohol for China was medium. Among the analyzed items， methanol had the highest risk value （82.917）， while natamycin had the lowest risk value （52.083）.ConclusionThe recommended detection items can be output by the established model according to the overall risk level of imported alcohol and the risk value of detection items. The model has high reliability and can provide a reference for the safety risk assessment and management of imported food.
