建立一个二层规划模型来研究企业数量与企业规模的关系.上层决策者(社会管制者)以社会平均成本最小化和社会平均效益最大化为目标选择发电企业的数量使得社会资源得到良好的配置,而下层决策者(发电企业)选择规模使其利润最大化.根据模型的结果分析了社会管制者对社会平均成本最小化和社会平均利润最大化的不同偏好对结果的影响.
A bilevel programming is proposed for studying the relationship between numbers and scale of generation companies. To optimize resources, the upper level decision maker(social regulation) chooses the number of generation companies to minimize social average cost and maximize social average benefit, and the lower level decision makers(generation companies) optimize their scales to maximize benefit. The influence on the model by choosing to minimize social average cost or to maximize social average benefit are analysed.
