摘要: 铁路运输是影响国计民生的主要行业之一,为在保证顾客服务水平的前提下,确定铁路货运最优价格,首先,根据生活实际,做出合理简化的假设,对费用和可靠性给以定量描述;然后,以总费用为目标函数,以容量为决策变量,以预先设定的可靠性作为约束条件,建立优化模型,并求得最优解;最后,标定参数进行算例分析,并探讨参数对最优容量和最优价格的影响。结果表明:该模型可以清晰地反映随着各参数变动最优解的变化趋势,能较好地体现垄断性行业的行业特性,并得出简洁的、基本合理的结果。

关键词: 垄断性, 优化模型, 最优价格, 最优容量, 最优边际费用

Abstract: Railway transportation is one of the major industries affecting the national economy and people's livelihood. In order to determine the optimal price of railway freight transportation on the premise that the service levels of customers were guaranteed. Firstly, based on the actual situation of life, the reasonable assumption was made and a quantitative description of cost and reliability were given, then,the total cost was used as the objective function. the capacity was used as the decision variable, the pre-set reliability was used as the constraint condition to make sure the optimization model was established and the optimal solution was obtained, finally, the calibration parameters were analyzed by examples, and the influence of parameters on the optimal capacity and the optimal price was discussed. The results show that the model established can clearly reflect the trend of the optimal solution with the variation of various parameters, which can better reflect the industry characteristics of the monopolistic industry and obtain concise and basically reasonable results.

Key words: monopoly, optimization model, optimal price, optimal capacity, optimal marginal cost
