本文针对采供双方风险规避的多属性逆向拍卖环境下的利润分配与采供关系建立问题,构建了非合作与合作博弈模型,分析了主体风险态度对利润分配结果的影响,得出建立和发展合作关系的条件,并确定了利润最优分配比例。结合仿真实验得出:1)采供双方非合作时,影响双方利润的因素:供应商成本参数,参与拍卖的供应商数量等。2)双方合作时,对利润的分配比例,受双方风险规避系数的影响;采购商提供给供应商的补贴受双方风险规避系数和讨价还价能力的影响。3)双方建立合作的基本条件需同时满足集体理性和个体理性,而长期合作的必要条件是双方效用最大化前提下的确定最优分配比例。
This paper establishes the problems of profit distribution and acquisition and supply relations under the multi-attribute reverse auction environment where both parties adopt risk aversion, establishes a non-cooperative and cooperative game model, and analyzes the influence of the subject’s risk attitude on the results of profit distribution, and then establishes and develops. The conditions of the partnership, and determine the optimal distribution ratio of profits. Combined with simulation experiments, it is concluded that: 1) Factors affecting the profit of the two sides when the two parties are not cooperative: the cost parameters of the supplier, the number of suppliers participating in the auction, etc. 2) When the two parties cooperate, the distribution ratio of profits will be affected by the risk aversion coefficient of both parties; the subsidies provided by the purchaser to suppliers will be affected by the risk aversion coefficient and bargaining power of both parties. 3) The basic conditions for establishing cooperation between the two sides need to satisfy collective rationality and individual rationality at the same time, and the necessary condition for long-term cooperation is to determine the optimal allocation ratio under the premise of maximum utility of both parties.
