放射性物质运输线路优化方法的研究

在放射性物质运输的活动中,为了使所选取的放射性物质运输线路相对最优,本文在给定的运输起点和终点并且具有时间窗约束的情况下,对运输活动的运输时间、运输成本和运输风险3个关键因素进行综合考虑,将其确立为3个目标向量。根据实际的运输任务,利用灰色关联度分析方法,从3个目标量中确定一个理想化的最优样本,以此为参考样本,通过计算各样本序列与该参考序列的关联度,对被评价对象做出综合比较和排序,选取最优的运输线路。本文为放射性物质运输线路的选择提供了一种分析方法。

Application of Gray Correlative Degree on Radioactive Material Transportation Route Optimization

In the radioactive material transportation activities,in order to get the optimal transport line of radioactive material, three key factors such as transportationduration,transportation costs and transportation risk,which are called as three taget vects,are taken into account in the case of a given transportation start and end with time windows constrained. According to the actual transport tasks,the gray correlation analysis method is used to determine an optimal sample from three target vectors. Using the sample as a reference sample,and calculating the correlation degree of each sample sequence with the optimal sample,a comprehensive comparison and taxis for the object evaluated are implemented and an optimal transportation line is selected. It provides an analysis method for selecting the transportation line of radioactive material.
