Research On Supplier Selection And Revenue Sharing Contract Mechanism Under Risk Environment In Supply Chain

Supply chain risk is becoming a challenge of present supply chain management,how to adopt effective prevention measures is a difficult problem that faced of the enterprise and the experts of SC.The supplier is the source of SC,which is the basis of stable operation and its performance is directly affects the efficiency of SC.The revenue sharing contract as an important mechanism of SC coordination can effective coordinate the members and optimal the system, which becomes an effective way to deal with the increasingly fierce market competition.So this paper mainly research on the following aspects.1.The evaluation system of supplier under SC risk management is constructed from the external and internal risk factors that may be faced of the supplier.The uncertain information is represented through fuzzy set and the values decision of experts are represented by trapezoidal or triangular fuzzy number.The different risk preference and weight value are considered and the TOPSIS method is improved.Their closeness coefficient distance attains the classification of the suppliers.2.Based on risk preference of partners in supply chain,the design of revenue-sharing contract is researched.The interval value of revenue coefficient is given when SC member is risk averse or risk prone.The value of revenue coefficient,wholesale price and expected profit affected by risk preference are discussed.It shows that the risk averse would let the other party derive the larger sales share in order to get the lower wholesale price and the more responsibility of risk the more revenue of the partner can derive.It reflects symmetry principle of profit and risk in the course of SC operation3.In a three-stage supply chain composed of a supplier,a distributor and a retailer,the coordination mechanism in fuzzy demand environment is researched.The parameters of demand function are regarded as triangular fuzzy numbers.The decision processes are analyzed under the decentralized and centralized decision,the decision model under revenue sharing contract mechanism is built.In the end,for directly analyze,a numerical example is given which suggests that the revenue sharing contract also can coordinate the profits of members in fuzzy demand environment.4.Based on the two retailers competition in supply chain,the decision processes of the decentralized decision,centralized decision and revenue sharing contract mechanism are analyzed.The results suggest that the order and profit of retailers,the profit of supplier,the upper limit of revenue sharing coefficients should be decrease between the more competing of retailers. It also suggests that the revenue sharing contract mechanism can coordinate the profit of members with retailer competition.
