线性规划综合运输网络合理规模研究

综合运输网络规模计算是评价现状综合运输网络合理性的重要依据，同时也是拟定规划网络方案的重要基础。从提高区域综合运输网络规模预测的科学性和协调性出发，以费用最省、时间最短、投资最低、环境影响最小为多个决策目标，分别以合理的客货运需求结构和各方式可能的规模为约束条件，建立Fuzzy线性预测模型。通过综合周转量分析方法，将综合运输规模预测问题转化为综合客货运方式结构优化问题，求得本问题模型的多目标折衷最优解。结果表明：在一定的方式结构和规模的限制下，任何区域内都能够确定一种适合本区域的最佳方式规模组合，使得广义成本最小。

Reasonable Scale of Multimodal Transportation Network of Linear Programming

The scale of multimodal network is one of the most important indexes to evaluate the reasonableness of the current network.Furthermore,it is the foundation on which the multimodal transportation plan is based.To enhance the efficiency and the compatibility of the forecast of the regional multimodal network,this paper presented a multi-objective optimization model under the principle of the minimization of the transportation expense,time,investment and environmental influence.And then a fuzzy linear programm...
