Research On Some Issues Of The Formation Mechanism And Coordination Management About Airline Alliance

The supply chain management is a new management in the last years. This kind of management principle can reduce a logistics to circulate time and social stock, decline cost, raise the product quality and management efficiency; many business enterprises have already treated it as the important tool of obtaining success in the future, to strengthen the competitive of the business enterprise. The supply chain is a network structure, filled with the supplier, the manufacture, and the seller etc, it is complexity, dynamic and cross, therefore it is full of uncertainty. These uncertainty factors not only will affect the performance of enterprise operation, but also will cause business enterprise produce delay, the cost increase, quality descends, stock increase, and the customer satisfaction descend etc...If we can't get to remove these factors in time, it will influence the whole operation level and competitive advantage of the supply chain seriously. Accordingly, how to prevent and cope with the uncertainty is important in planning a supply chain strategy.According to the problem that the operation of supply chain management and the shortage of related research about supply chain manages current. This paper mainly analyzes the two kinds of uncertainty: demand and structure, in the process of supply chain operation.First, this paper analyzes the concept and characteristic of uncertainty and supply chain, then conclude and analytical the category of uncertain factor and various reason to caused uncertainty from the different point of view such as structure and environment etc.The supply chain is full of uncertainty. In these uncertainty, the demand uncertainty is the most difficult to control. The uncertainty in market will give impediment in production decision and the logistics decision of the supply chain business enterprise, through the study of uncertainty factors to the supply chain demand, can help a business enterprise to look for assurance from the uncertainty, draw up valid marketing strategy. The paper not only analyzes the cause of formation from the environment and the consumer factor qualitatively, but also thorough analyzes consumer uncertainty of purchase decision quantitatively. Then introduces simplexes the strategy of preventing demand uncertainty: forecast, information share, supply chain contract etc., according to this situation, carries on the thorough research to that contract problem between buyer and seller under supply behind demand in realistic economic activities.However in recent years, contract problem in supply chain between buyer and seller is mostly under oversupply, to stimulate seller to increase the order. But the study of promote harmonious development under supply behind demand to limit the order is less. However the phenomenon of supply behind demand exist in realistic economic activities, special in the resourcest.This text exactly according to this situation, carries on the thorough research to that problem which how to limit order, how to turn down the risk about both buyer and seller, how to promote supply chain diapason development in the presupposition of random market, build price contract model in supply chain under supply behind demand.The strategy of preventing can lower the influence of the demand uncertainty, but the result isn't very obvious (especially for creative type, their demand uncertainty can predict badly).Therefore how to design reasonable structure of the supply chain to lower uncertainty is an important problem. The paper introduces the characteristic of the structure of supply chain simply, analyzes the factor of causing structure uncertainty in the supply chain qualitative from the different point of view such as the communications and the topologies and the mode.Set up the reasonable supply chain structure is to reduce uncertainty in the supply chain.Throught the complex system can be decomposed into series or parallel systems, this paper studies the structural models of supply chain from the different point of view such as dimension of the supply chain is the complexity and the number of supplier be selected is uncertainty. The method of the superior allotment about the biggest reliability, the minimum expenses and the supplier choice problem is discussed.The strategy of flexible is used to lower the uncertainty. The paper set forth flexibility concept, flexibility characteristics, necessity of implement flexibility, performance carried out flexibility results etc systemic; and introduce strategy of flexibility in practice; introduce how to ensure the efficient frontiers of supply chain, help the decision-making t to look for the best choice of flexibility's level, the equilibrium point flexible value and cost, provide technical support for enterprise to invest and choice parameter of flexibility, further put forward the arithmetic of the efficient frontiers of supply chain.
