在降低相关运输风险方面，危险材料路线选择是一个关键决策。本文提出了一个决策支持系统，用于评估备选配送路线的行程时间、风险和疏散影响，同时协调应急响应部署决策和危险物资路线。拟议的系统提供以下功能：(1)从成本和风险最小化的角度确定替代的非主要危险物资分配路线；(2)为及时对事故作出反应，确定危险物资第一反应紧急服务单位的地点；(3)确定从受影响地区到指定避难所的疏散路径，并估计相关的疏散时间。拟议的系统已在希腊阿提卡Thriasion Pedion的高度工业化地区内实施、使用和评估替代危险材料路线决策。上述功能的实施分别基于两个新的整数规划模型，分别用于危险材料路线问题和应急单位选址问题。利用作者开发的现有启发式算法求解简化的布线模型。提出了一种新的求解应急响应单元选址问题的拉格朗日松弛启发式算法。本文的重点是对拟议的决策支持系统的组成和功能进行阐述。重点介绍了选址模型的两个新的数学模型和新的求解方法。
Hazardous materials routing constitutes a critical decision in mitigating the associated transportation risk. This paper presents a decision support system for assessing alternative distribution routes in terms of travel time, risk and evacuation implications while coordinating the emergency response deployment decisions with the hazardous materials routes. The proposed system provides the following functionalities: (i) determination of alternative non-dominated hazardous materials distribution routes in terms of cost and risk minimization, (ii) specification of the hazardous materials first-response emergency service units locations in order to achieve timely response to an accident, and (iii) determination of evacuation paths from the impacted area to designated shelters and estimation of the associated evacuation time. The proposed system has been implemented, used and evaluated for assessing alternative hazardous materials routing decisions within the heavily industrialized area of Thriasion Pedion of Attica, Greece. The implementation of the aforementioned functionalities is based on two new integer programming models for the hazardous materials routing and the emergency response units location problems, respectively. A simplified version of the routing model is solved by an existing heuristic algorithm developed by the authors. A new Lagrangean relaxation heuristic algorithm has been developed for solving the emergency response units location problem. The focus of this paper is on the exposition of the proposed decision support system components and functionalities. Special emphasis is placed on the presentation of the two new mathematical models and the new solution method for the location model.
