摘要
研究最简单的两级供应链在市场价格随机条件下数量折扣契约是否能协调应对突发事件。突发事件引起市场需求规模发生剧烈变化,同时市场价格跟随供求关系随机波动而波动,建立两级供应链应急数量折扣契约模型。通过研究得出以下结论:基准数量折扣契约不能协调应对市场价格随机的突发事件,若适当调整批发价,调后的数量折扣契约能优化协调应对引起市场价格随机的突发事件。给出供应链最优订货与定价策略。并与市场价格固定的突发事件与无突发事件下的两种情形进行了对比。最后,通过算例进行验证。
This paper examines whether the supply chain can coordinate to respond to unconventional emergencies under quantity discount contract or not. Unconventional emergencies not only cause large scale fluctuations in market demand, but also make retail prices fluctuate randomly with the change of supply and demand relationship in the market. On basis of the background, we build a quantity discount contract model aiming to responding to unconventional emergencies, and then draw the following conclusions through its analysis- the benchmark quantity discount contract cannot coordinate to respond to unconventional emergencies, while after appropriate adjustment, it is possible. Moreover, we provide the optimal ordering and pricing strategies in supply chain in answer to unconventional emergencies, and compare them with the results under the conditions of conventional emergencies and without emergencies respectively. In the end, we verify the validity of the conclusions above through numerical cases.
