零售商为损失厌恶的供应链优化与协调问题

研究由单个风险中性的供应商与单个损失厌恶的零售商组成的两级供应链中,当随机需求依赖于价格时的供应链问题。不同于以往的文献,研究发现,当随机需求依赖于价格时,损失厌恶零售商的最优订购数量随其损失厌恶程度的增加而减少,且随批发价格的增加而减少;最优零售价格则相对损失厌恶程度、批发价格在一定条件下具有单调性;此外,还证明了批发价格合约不能协调供应链。最后,通过数值例子验证了所得结论。

Supply Chain Optimization and Coordination Mechanism with a Loss Averse Retailer

The traditional treatment of supply chain models largely focuses on the value of a given cost or profit measure. Owing to the highly uncertain demand in real optimization of the expected world, the use of the expec- ted objective measure may be not justified. In this paper, in the loss aversion metric norms, we study the impact of loss aversion on a retailerb （newsvendorb） optimal order quantity and optimal retail price under price-sensitive stochastic demand in a supply chain. We find that the order quantity is decreased in loss aversion coefficient, and also decreased in wholesale price; the loss-averse retailer~ optimal retail price is relatively conditioned mono- tone with loss aversion coefficient and wholesale price. Furthermore, we proved that the wholesale price contract cannot coordinate the supply chain. Finally, we verify our conclusion with a numerical example.
