Abstract:
This paper studied the food safety evaluation model based on big data, according to the social supervision mechanism, focusing on the responsible subject of food safety issues. Based on big data technology, a three-dimensional spatial model of food safety and its standardization system were established. An evaluation model of food safety problems was established, and the evaluation indexes were constructed according to the early,middle and late stages of food safety, which comprehensively covered all stages of food safety problems. The network hierarchy process was used to evaluate food supervision situation, and a comprehensive supervision evaluation data model was constructed through data research. The experimental results verified the model with high reliability and effectiveness can be used to guide the system construction of food safety problems, which has great practical significance.
