摘要
在市场需求分布不定的环境下,考虑产能限制以及政府价格干预,研究了供应链网络均衡问题。借助变分不等式理论,给出了供应链网络中各层决策者以及整体均衡条件。利用对数二次预测校正算法,进行了数值算例分析。结果证明:当需求为分布不定时,采取保守策略的零售商利润少于随机需求分布已知的情形;同时,由于信息的匮乏,容易造成制造商的盲目生产。
Considering the production capacity constraints and a binding ceiling price of goods, the supply chain network equilibrium problem is examined under distribution free environment. By utilizing variation-al inequality, the equilibrium conditions of each level and the whole network are given. The equilibrium patterns are obtained via logarithmic-quadratic proximal prediction-correction. The results show that the retailers＇ profit will decrease by taking conservative strategy when the market demand is distribution free. Meanwhile, it may also cause the manufacturers＇ blind production due to poor information.
