Supply Chain Response Decision Method Based On Coordination System

To satisfy the customer's demand on price, quality, time, customization and so on, enterprises have to collaborate closely to enhance coordination. Supply chain management mode grew up in 1990s is suitable for this trend. Coordination among supplier, manufacturer, distributor and retailer in supply chain is one of the critical problems in supply chain management, and it is the guarantee of supply chain efficiency. Supply chain is operating in dynamic and variable environment, the uncertainties would cause new coordination demand or affect existing coordination strategies through information updating, which would make the supply chain lose coordination. To fulfill the practical and theoretical demand for supply chain response coordination with uncertainties, the paper constructs the supply chain response coordination theory system and studies the key response decision technologies for supply chain coordination.First, it constructs the supply chain response coordination theory system. Definitions of supply chain response coordination and relative concepts have been made on the base of traditional theory of supply chain coordination. Factors affecting supply chain coordination response decisions have been analyzed and functions of supply chain response coordination have been discussed. The coordination levels and mechanism in supply chain response coordination with uncertain environment have been also studied. Decision problems are classified with the criterions of time and function. Emphasis has been put on the classification based on coordination demand. Hierarchical control structure in supply chain response coordination and its elements are proposed and analyzed based on the control theory of large scale system. It also describles the response coordination's interactive process.Second, it studies the supply chain coordination response decision method facing emergency coordination demand. A kind of preference adjustment rule has been put forward to rich constraint satisficing optimization method with analysis to preference description procedure of decision maker. Propose typical problems in supply chain coordination response decision facing emergency coordination demand, such as emergency ordering problems in once consumed and continuous consumed supply chain system, and supply chain distribution decision problem under manufacture interruption. To solve such problems and get satisfying objective stategies, it constructs satisficing optimization models and corresponding algorithms based on constraint satisficing optimization method.Third, it studies the response method of supply chain coordination strategies under information update. Analyze the effect of information update, and come up with the regulation process of supply chain coordination strategies under information update. Put forward a kind of profit share contract and investigate its adjustment method when demand price coefficient varied. Regulation method of buyback contract facing fuzzy random demand update is considered. Describe the standard pricing strategy for substitutes and its adjustment method with supply information update. The problem is further extended to more general conditions.At last, supply chain response coordination theory and response decision methods are applied to certain solar water heater supply chain. Practical cases studied cover supply chain response coordination theory and key response decision technologies proposed, which demonstrate the feasibility and efficiency of the proposed methods.Uncertainty has an important effect on supply chain coordination. Research results on supply chain response coordination system and response decision method would rich the supply chain coordination and management theory, and improve the efficiency of supply chain coordination response decision.
