Research On Food Quality And Safety Risk Measurement From Supply Chain Perspective

The problem of food quality and safety is constantly erupting,and it is urgent to restrain the risk of food quality and safety.It is of great practical significance to study the food quality and safety risk from the perspective of supply chain.Considering the positive correlation between the level of food quality and safety risk and the cost of food quality and safety that need to be invested to reduce the risk to a normal and reasonable level,this paper divides into different chapters to make a detailed analysis and study on the supply chain risk,the cost input of quality and safety level and the risk measurement method required.The research process combines the quality safety cost function,and applies the Va R model to convert the difficult food quality safety risk measure into a measure of the quality safety cost input required for the corresponding risk prevention and control,thereby realizing the visualization of the risk.At the same time,according to the risk conductivity of each node in the food supply chain,the quality and safety risk values of the upstream supply chain and the downstream seller of the food supply chain can be measured by Monte Carlo method.Furthermore,the food quality safety risk prevention and control of sellers is divided into two types: single control upstream transmission risk and two-way control upstream transmission and self-generated risk,and the total risk of seller is deeply analyzed.Based on the combing of the relevant literature in the second chapter,through the theoretical analysis of the risk and cost of food quality and safety in the third chapter,the basic theoretical model is deduced.In the fourth chapter,the principle of risk measurement model Va R is introduced,and the model is combined with the actual quality and safety cost by means of risk analysis.In the fifth chapter,we compare the trends of different risk combinations,realize the visualization of risk specific values,divide the risk level and select the minimum risk combination,complete the risk rating and risk control,and finally draw the research conclusion.The results show that:(1)even if the parties in the supply chain are rational cost investors,considering the transfer effect and self-regulation,the risk value can only be controlled in the relatively low range,not reduced to zero,and the corresponding risk grade is the lower risk area.(2)the larger the measured risk Va R value is,the greater the corresponding potential risk CVa R value will be.(3)when the production,processing and sales links meet the quality and safety standard,when the downstream seller's willingness to control the risk of other paths accounts for 20% of the total risk willingness to control the risk,the primary control of the transmission risk and the secondary control of the risk are the best choice for the decision maker of the seller enterprise to control the risk.
