摘要
为了避免有害物品在运输过程中发生重大事故,分析了避免重大事故发生的条件,即尽量避开可能产生严重后果的路段.建立了综合考虑运输风险、平均后果和总后果的路径选择模型,并利用线性加权的方法对3个目标进行处理,使模型可以利用最短路算法进行求解.该模型通过控制平均后果和总后果,能避开可能产生严重后果的路段.最后,给出了1个应用算例.
In order to avoid serious accidents in the transportation of hazardous materials, the condition against a serious accident was analyzed, i. e. , avoiding passing the route with a serious consequence as possible. A model for route selection was set up by taking population risk, average consequence and total consequence as the objectives to avoid serious transportation accidents, and by using the weighted method, the model can be solved by the shortest path algorithm. With this model, serious accidents in the transportation of hazardous materials can be avoided by controlling the average consequence and the total consequence. At last, a calculational example was given to show the validity of this model.
