当前市场条件下,企业间的竞争通常只考虑库存竞争,而忽略了价格竞争。针对这一问题,在需求不确定且与价格具有相关性的前提下,建立了基于报童问题的需求模型。该模型面向包含多个企业的横向市场。同时,这些企业间采用联合定价/存货,并利用价格来竞争市场需求。分析了一个基于报童问题的定价博弈,通过增加不确定性延伸了需求模型。模型中各个企业通过自身的价格弹性影响自身的市场需求,同时也影响着其他企业的市场需求。
According to the ignorance of price competition, facing stochastic price-dependent demand, a demand model based on the newsboy problem is proposed. This model considers a horizontal market of multiple firms. They make joint pricing/inventory decisions and use price to compete for market demand. Pricing games are analyzed based on newsboy problem. Demand model with substitutable property is established by introducing uncertainty. The firms' price influenced their own demand through self price elasticity and others' demand through cross-price elasticity in the model.
