危险品运输路径选择多目标优化

Multi-objective Optimization of Hazardous Materials Transportation Route Selection

为合理规划运输路径,科学评估危险品运输过程中的风险。在运输网络中,以路段发生事故的概率、事故敏感人数、交通损失及应急救援能力来定义路段上的运输风险,建立了一个以最小化风险、运输距离与运输时间为目标的优化模型,并利用AHP法对目标进行集成,将模型转化为单目标问题进行求解,最后通过实例对模型与算法进行验证。

In order to evaluate the risk of hazardous materials transportation,plan the transportation route reasonably.In transport networks,with the number of sections is sensitive to the probability of accident,accident loss,transportation and emergency rescue capabilities to define a stretch of road transportation risks,set up a to minimize risk,transportation distance and transportation time for target optimization model,and use the AHP method to integration of target,the model is transformed into single objective problem to solve,finally by an example to verify this model and algorithm.
