Research On Agri-product's Supply Chain Management For Quality Safety And Its Information Platform

Food is number one thing in everyday life. The safety of agricultural product (agri-product) is vital to people's life, so each country's government in the world pays more attention to it.From the perspective of quality-safety, an effective agri-product's supply chain (SC) management system is developed in this dissertation. An information platform that supports the system is also constructed to enhance the agri-product quality-safety level.First, supply chain's partner selection in establishing the SC is studied. Fuzzy synthesized appraising approach is used to select the partner which is the foundation of the cooperation relationship. Adverse selection risk is reduced from the establishing of the supply chain which ensures the quality-safety.Second, profit assignment in executing the SC is settled. Principle-agent model and incentive theory are used to analyze the relation between the seller and the supplier in agri-product supply chain. The effort level of the supplier is enhanced by profit assignment. Risk preference of the agri-product supplier and the seller is considered, and the risk aversion type is emphasized according to the real world.Third, contract model in supervising the SC is established. Sampling tactic is designed to supervise the supply chain's operation which can reduce the moral hazard. Through analyze the sampling tactic and the inside/outside failure costs, supervising can be realized.Final, quality-safety information platform is set up using modernized information technology which provides integrated safeguard for supply chain's operation. Government monitoring and information sharing can also be realized. What's more, consumers can surveillance the production, processing and selling phases by this platform.In conclusion, contacting theory, principle-agent theory and game theory are used in this thesis. Supply chain coordinated agri-quality safety management system and its information supporting platform are proposed. Apart from the theory analysis and operating approach constructing, this thesis extends the application scope for supply chain, and finds an effective method for enhancing the agri-product's quality-safety.
