考虑一条风险规避型的“单制造商—单零售商”双渠道供应链,通过求解供应链系统分别在集权模式和分权模式下最大效用的Karush-Kuhn-Tucker(KKT)条件,得到其在需求扰动前后的最优定价策略和生产决策。研究表明,风险规避系数与最优价格成反比,与最优生产量成正比,与二者的值有关,与不同决策的分界点无关;需求扰动时供应链的决策只与扰动量有关,与风险规避系数无关;集权模式下供应链知道需求扰动的价值与风险规避系数正相关。
Consider a Karush-Kuhn-Tucker (KKT) condition that maximizes the utility of the supply chain system in both centralized and decentralized modes, respectively, considering a single risk-averse “single-manufacturer- single retailer” Its optimal price strategy and production decision before and after demand disturbance. The research shows that the risk aversion coefficient is inversely proportional to the optimal price and directly proportional to the optimal production, which is related to the value of the two. It has nothing to do with the demarcation point of different decision-making. The supply chain decision- The avoidance coefficient has nothing to do with it. In the centralized mode, the supply chain knows that the value of demand disturbance is positively correlated with the risk aversion coefficient.
