Research On Supply Chain Operational Mechanism Based On Stability

Supply chain, as a cooperative alliance consisting of many member enterprises, can play the best utility while maintaining the stability of its operation condition. Supply chain is a virtual organization in which each member is an independent entity with different interests, different business philosophies, different value orientation and limited rational boundary and so on. So, it often leads to a conflict between individual behavior and overall goal of the supply chain, which will affect the stability of the supply chain operation. Therefore, in order to promote the operational stability of the whole supply chain system, the research on establishing and perfecting the operation mechanism during the operation process of supply chain is of great influence on enhancing the overall operating efficiency, competition ability and the profit level of the supply chain.On the basis of informed research and consultation of a large number of domestic and foreign literature, in order to establish a friendly and cooperative relationship and achieve a dynamic balance of the stability of the supply chain operation, this paper studies all kinds of effective operational mechanism of supply chain in terms of stable operation of the supply chain system, and attempts to promote the cooperative parties in the supply chain operation, through improving and perfecting the internal operational mechanism of the supply chain system, to select a cooperative behavior which is the most beneficial to the development of whole supply chain . The main work of this paper can be summarized as follows:1. Influence mechanism of the stability of the supply chain operation was studied. A conceptual model of the influence of stability of the supply chain operation was set up by using the theories related and defining the concept of the stability of the supply chain operation and analyzing factors influencing the stability of the supply chain operation. Concrete influence of uncertainties, risk of the supply chain, as well as other factors on the stability of the supply chain operation was analyzed selectively.2.Trust mechanism of the supply chain based on stability was studied from three points of view: Firstly, the process of trust game of cooperative partners was analyzed by using the game theory also the construction of trust-forming mechanism of the supply chain enterprises was researched. It is constituted of the process mechanism, the characteristic mechanism and the institution mechanisms of trust-building, according to which a trust-forming mechanism model of the supply chain was proposed. Secondly, related models of contract design were established, and the impact on corporate behavior based on a unified contract design and the design of different contract was discussed respectively. The institutional basis of preventing trust crises of the supply chain is the design of the contract. And the contract design aimed to inhibit enterprises from moral hazard and promote a credible business conduct. Thirdly, elements of maintaining supply chain trust mechanism and approaches to build supply chain trust mechanism were discussed and a model of implementation process of the supply chain trust mechanism was constructed.3. In the research of cooperation mechanism of the supply chain operation, the model of the influence factors of the supply chain cooperative relationship and the index system of the ingredients of the supply chain cooperative relationship based on the stability were established in the first place. Effect of the selection of the supply chain partner on the stability of the supply chain operation was mainly focused on. Two possible kinds of conflict modes produced by the node enterprise were discussed, namely the effect of the social behavior of waste and treachery on the stability of the supply chain operation. In the second place, a comprehensive evaluation index system of the supply chain members was constructed. And an evaluation model of supplier selection that combining entropy and TOPSIS was established. This model can effectively avoid the subjective factors existing in traditional evaluation method, and evaluate the suppliers comprehensively, concretely and objectively.4. The interest's distribution as well as the encourage mechanism and supervision mechanism during the operation of the supply chain were studied. For one thing, the interest's distribution of the supply chain enterprises was analyzed using the game theory. Two models about interest's distribution and management of the supply chain members were discussed: the general distribution model based on resources and the contribution rate and the revenue sharing model of the Shapley value. For another thing, problems of the design of the supply chain encourage mechanism and supervision mechanism were discussed, and a negative incentive model as well as a supervision mechanism of the supply chain model were put forward to prevent the supply chain from moral hazard. And the two models took effect from different points by penalizing the nonperformance of the contract..5. In the study of information coordination mechanism of the supply chain, firstly, the effect of the information coordination on the stability of the supply chain operation was detailed analyzed, on the basis of which the constitution of the information sharing resources, models of information sharing as well as construction of the information sharing platform in the supply chain were then researched in detail. Secondly, in order to reduce the influence of distortion of the demand information, the thesis attempted to use a linear regression forecast model to predict the needs of all enterprises in the supply chain nodes by decision-making of the production or making corresponding orders .The model could control and reduce the bullwhip effect in the supply chain, improve supply chain agility and reduce the cost of the supply chain. And the simulation of the model has showed that the method could inhibit the impact of bullwhip effect well.6. By selecting several key indicators among the trust, cooperation, interest's distribution, and information coordination mechanisms related to the stability of the supply chain operation and taking other factors into comprehensive consideration, a comprehensive evaluation index system of the stability of the supply chain operation was constructed, in which the quantitative and qualitative indexes were screened respectively, by using PCA (principal component analysis) and compositor method of binary comparison based on fuzzy set theory, in order to determine the key indexes that greatly influenced the stability of the supply chain operation. And a model of FCE (fuzzy comprehensive evaluation) based on two-stage was constructed to assess the stability of the supply chain operation.
