Abstract: This paper explores supply chain versus supply chain competition model with customer choice preference. Based on stochastic user equilibrium theory, variational inequality and logit model, the market share and product price about the winning supply chain are examined, and the competition equilibrium model can interpret reasonably the customer's choice preference for the same product. The paper concludes with a numerical example and proposes future research ideas.

Key words: supply chain versus supply chain competition, customer choice preference, stochastic user equilibrium, variational inequality

摘要： 本文建立了具有顾客选择偏好的供应链与供应链竞争随机用户网络均衡模型。基于随机用户均衡理论和logit模型,利用变分不等式,得出在竞争均衡态下胜出的供应链,其市场占有率和所提供产品的市场价格等参数。该模型从供应链与供应链竞争的角度,很好刻画了顾客的对具有价格等差异性的同类产品的选择偏好,并给出了研究思路,适用算法和合理的经济解释。
