【摘要】：为了减小危险品运输过程中各人口聚集区域间风险分布差异,提出了一种多源-目的(OD)间同时进行危险品运输时考虑风险公平的车辆调度优化方法.提出了采用标准差来衡量各人口聚集区域间风险差异的风险公平性评价方案.设计了考虑风险分布公平的车辆调度数学模型,通过获取周期性调度方案来减小人口聚集区域间的风险差异,实现区域风险分布公平的目标.为了降低求解难度,将模型分解并增加决策者交互环节后,设计了两阶段算法求解.通过算例分析表明,该方法可在不同OD间同时运输危险品时,通过调节运输车辆选择不同路径运输的频次,在保证运输总成本和总风险可接受的前提下,达到风险公平性最优的目标.
[Abstract]:In order to reduce the difference of risk distribution among population concentration regions in the transportation of dangerous goods, a vehicle scheduling optimization method considering risk equity in multi-source-ODO transportation of dangerous goods at the same time is proposed. A risk equity evaluation scheme based on standard deviation is proposed to measure the risk difference among different population concentration regions. A mathematical model of vehicle scheduling considering fair risk distribution is designed to reduce the risk difference among population concentration regions by obtaining periodic scheduling schemes to achieve the goal of equitable risk distribution in the region. In order to reduce the difficulty of solving, a two-stage algorithm is designed after decomposing the model and increasing the interaction of decision makers. The analysis of an example shows that this method can be used to transport dangerous goods among different OD at the same time, by adjusting the frequency of transportation vehicles to choose different routes, under the premise that the total transportation cost and the total risk are acceptable. Achieve the goal of risk fairness optimization.
