An Approach To Supply Chain Alliance Based On DEA And Encouragement Mechanism

Supply chain is an alliance of multiple node enterprises united in a certain form. The performance and contribution of each node can influence on the whole alliance. In this light, the Paper deepens the research on the performance evaluation and encouraging mechanism for the node enterprises etc.The paper firstly evaluates the performance of supply chain alliance based on DEA,designs the performance evaluated model of supply chain alliance and gives the selectedrule of the input and output, then on that bases, the paper constitutes the evaluated rule ofsupply chain alliance. In order to avoid the impact of imprecise factors, a fuzzy DEAmodel, combined with the Bayesian learning network, is put forward to ameliorate theabove mentioned model. The paper sets up the model of finding the worse members inthe chain and commending the ameliorative information, it can distinguish the congenermembers in a supply chain alliance, locate the weakness of the member and give thedevice to solve these problem, based on this model, it brings forward an orbit model ofcollaboration which can frame the commonly cooperative approach among the membersin the supply chain alliance and forecast the trend of the collaboration. With the leastmaturity cell and the payoff ability of the cell, the paper opens out the connection amongthe alliance, which is the gist of fair distribution. Aimed at selecting the cooperativeassociates in an effectual way, the paper advances the three phase means, it wash out thespare members in different phase, avoid appraise all spare members in all angels andreduce the cost of selecting. Then, by applying game theory, the paper designs themechanism advancing the steady collaboration. For accelerating the communication ofthe information among the alliance, the paper dreams up an information revelation modelbased on principal-agent, the members may maximize his utility by revealing truthfully his ability type in optimal.The paper deeply researched into the system of supply chain alliance and putted forward some models. This achievement has significant meaning to the automation, and has very high reference value to the research of supply chain.
