危险品运输网络中运输方式和路径优化研究

在危险品运输网络中，往往有多种运输方式和多条运输路径。不同运输方式在不同路径上发生事故所造成的损失不同，不同运输方式的单位运输成本也不同。本文研究了在给定运输起点和终点的情况下，在综合考虑事故所造成的损失最小和运输成本最小的情况下，运输方式和运输路径的选择方法。通过一个仿真例子说明了模型的求解方法和实际效果，并与单一运输方式的方案进行了对比。结果表明考虑运输方式的组合，在一定程度上可以降低危险品运输过程中的社会总期望损失和运输成本。

Research on optimization of transportation mode and route for hazardous materials transportation network

In a given hazardous materials transportation network,there are many modes and routes.Different transport modes with different units transport costs cause different incidents losses on different paths.Based on provided starting point and end point,the optimal transportation mode and route were studied by comprehensive considering how to minimize the incidents losses and the transportation cost.Finally,gives out an example was presented to show the procedure of solving the model,and it was compared of the so...
