Research On Operation Optimization Of Supply Chain With Risk Fairness Concerns And Risk Sharing Mechanism

With the changes of economic structure and rapid development of the industrial chain,supply chain management has become the hot issue in both industrial and academic circles.In the early stage,most of supply chain theory based on the assumption that the decision makers are risk neutral.However,in the real economic activities,enterprises face various risks caused by more complicated and uncertain factors in the process of supply chain operation management.Recently,some experimental economics studies have found that decision makers are considered to be irrational or bounded rational.One of the most representative views of behavioral research is that 'people have social preference'.Compared with the traditional supply chain operation management,the decisions of supply chain will be influenced by behavioral factors.Among the typical behavioral factors,fairness concern is an important factor influencing decision-making behavior in people's social preferences.Some researches on supply chain fairness concerns focus on whether the economic profit distribution is fair or not,and establish a utility function model by introducing a fair reference point.However,most of studies neglect the risk generates from the volatility of the return caused by the random yield or the demand uncertainty in supply chain operation management,and also produce the risk fairness concerns.The supply chain entity not only pays attention to the fairness of the distribution of economic results,but also concerns about the fairness of the risk sharing.Therefore,this dissertation studies the risk fairness concerns from a new perspective and explores the deep level mechanism of mutual decision makings of supply chain agents.We propose the concept of risk fairness concerns and introduce it into the supply chain operation management to enrich the research system of supply chain's behavioral operations and optimization.The risk generated by demand uncertainty and random yield are captured by different risk measurement,which incorporated into the utility system of the supply chain.We investigated how risk fairness concerns influences the decision-makings and profits changes of supply chain agents,and the supply chain coordination.Finally,we propose several risk-sharing mechanisms under different risk environments,and discuss the impacts of each mechanism on supply chain profits.In first part,the dissertation summarizes and analyzes the supply chain management,supply chain risk and behavioral factors from the aspects of actual background and theoretical research progress.Then we propose research questions of this dissertation and explain research significance from the theoretical and practical aspects.Additionally,we combined with qualitative analysis and quantitative analysis,and define the technical roadmap and innovations for the study.In the second part,we systematically introduce the domestic and foreign literature research which related to the research content of this dissertation,and point out the difference and connection.It mainly includes supply chain operation management,behavioral operation management,risk aversion preference,and supply chain management with random yield and demand.In the third part,it considers the impact of the risk fairness concerned newsvendor problem on supply chain performance.Through applying the downside risk approaches to depict the real market risk which incorporate it into the utility function and establish the model.In addition,we compare the optimal decisions and profits changes of suppliers,retailers and supply chain system.We propose a risk sharing mechanism based on risk fairness concerns and Pareto Improvement can be achieved in a certain condition.In the fourth part,based on the study of chapter 3,we consider the supply chain operation problems with risk fairness concerned supplier in the complex risk environment with both random yield and demand uncertainty.We investigate the influences of risk fairness concerns supplier on the optimal decision makings and overall performance of supply chain agents and system.In the fifth part,we study a two-echelon supply chain with a single supplier and a single retailer in the context of stochastic supply and demand.The retailer is in a dominant position in the supply chain.We propose several different risk-sharing mechanisms and compare the impacts of each risk sharing contracts on the expected profit of the supply chain.Finally,we summarize the research work and give some conclusions.Moreover,based on the research limitations,some future research prospects and thoughts are proposed.
