Research On Supply Chain System Coordination Based On Chaos Theory And Game Theory

With the development of supply chain management,more and more enterprises recognize that the supply chain system(Abbreviated as SCS) coordination becomes the focus to improve the supply chain competitiveness. For the reasons of interests,there often exists confrontation and competition between the two sides in the establishment of partnership,which requires the node enterprise to form the relationship of coordination and cooperation in the supply chain systems. However,the coordination and cooperation of SCS can not be achieved overnight, but to be formed gradually in constant dynamic evolution of node enterprises in SCS. Therefore, it is urgent need for depth analysis of the behavior of SCS members during the dynamic evolution in competition and cooperation, in order to promote coordination in SCS,and enhance SCS competitiveness.Bases on systematic engineering thought, unifies chaos theory and game theory, the thesis devotes to systematic study on SCS coordination by theoretical analysis and dynamic simulation model. So the research is a necessary complement to the traditional supply chain management theory.It will surely provide important theory reference to improve supply chain management theory and practice,and it also give a practice guide to the promotion of chaos theory to actual economic management. So major work and research findings in the thesis were as follows:(1) The three-level-view coordination of SCS was proposed,i.e.including of competition type coordination between enterprises at the same level, cooperative type coordination betweeen up and down stream enterprises, and adaptive type coordination of SCS vis to vis the environment.And the research idea of combining chaos control and system coordination theory and approach are put forward to SCS coordination.(2) Based on the output game model, the output coordination of two enterprises at the same level in SCS were researched form the aspect of static state and dynamic state, the rusult shows the same level suppliers must establish a competitive type coordination relationship, and provides a theoretical basis for them to build competitive-type coordination relation. In which dynamic production coordination is based on chaos theory, and it is carry out a ground-breaking research on the complex dynamics of production chaotic behavior and corresponding changes in profit collaborative caused by speed of the production adjustment. Combining game strategy features of both sides, the parameters adaptive feedback control method was applied to effectively lead the system from chaotic state into the equilibrium state. And the impact of the production ceiling control to the average profit of two companies at the same level in SCS was researched through numerical simulation, according coordinate measures were put forward to enterprises at the same level in SCS.(3) The price and inventory co-ordination problems were researched between up and down stream in SCS. Based on Stackelberg product game pricing problem under random demand, price coordination problem was studied between up and down stream enterprises (manufacturers and retailers) in SCS. Through theoretical analysis and coordination simulation based on stochastic demand subjecting to the uniform distribution and the normal distribution, comparatively research on the strategies of optimal order quantity, optimal pricing and profits for SCS under the circumstances of the basic conditions, information sharing, centralized decision-making and four kinds of price discounts on non-sharing of information, the results of theoretical analysis and numerical simulation results is fully consistent,and accord with the actual situation, which provide a theoretical reference to choose the right coordination measures of upstream and downstream enterprises.Besides based on a SCS model including manufacturers and retailers, the chaotic behavior of retailer's stock relative to discount rate in SCS is studied by numerical simulation methods, then the innovative methods of feedback control on the manufacturer's production is put forward.And the fee of the warehouse construction share by Shapely value in joint inventory management is given a pilot test, so provide a theoretical reference for inventory coordination of the upstream and downstream enterprises in SCS.(4) The mechanism of SCS adapting to the ever-changing environment is studied, and the conditions to guide enterprises to implement green supply chains are analyzed in the case of market mechanism and government macro-control by game evolution theory. A dual coordination mechanism of internal adjustments and external inspiration was proposed for SCS adapt to the environment, and guide the core enterprises to adopt the green supply chain management.(5) Applied theoretical research conclusions, a preliminary analysis and application to coordinate measures in coal industry SCS was conducted. The issues of the production competitive coordination between the same level coal enterprises, the cooperative coal prices coordinate between upstream and downstream enterprises and SCS evolutive to the green supply chain are analyzed,at last countermeasures are put forward.
