A methodology is proposed to evaluate and rank potential sites for facilities dealing with hazardous materials (HAZMAT). The proposed methodology incorporates HAZMAT route planning into facility siting while considering transportation preferences and challenges. The area of interest is divided into smaller zones representing potential sites for a HAZMAT facility. A multimodal transportation network including railways and roads is considered for transportation of HAZMAT. Each zone is evaluated based on its accessibility from a set of selected points of interests (POIs), which are defined as potential origin/destination points for transportation of HAZMAT. The shortest routes between each POI and potential zones are evaluated based on a cost function which can accommodate multiple criteria to determine the associated disutility for each potential zone. Finally, zones are ranked based on their cumulative disutility scores. The proposed analysis method is quantitative, and at the same time it is adequately flexible to allow inclusion of subjective criteria. Application of the proposed methodology is demonstrated for identifying optimal locations for a HAZMAT facility (e.g., a nuclear facility) using the Canadian province of Saskatchewan as an example. Three scenarios were evaluated including (1) all network segments and POIs were treated equally, (2) network segments were rank ordered based on their functional classification while POIs were treated equally and (3) network segments were rank ordered based on their functional classification with preferences given to specific POI(s).

基于运输偏好的危险材料设施选址案例研究场景

提出了一种方法来评估和处理危险材料设施的潜在场所（HAZMAT）。拟议的方法将HAZMAT路线规划纳入设施选址，同时考虑运输偏好和挑战。感兴趣的区域被分成较小的区域，代表了HAZMAT设施的潜在场所。考虑使用包括铁路和公路在内的多式联运网络来运输HAZMAT。根据每个区域的可访问性，从一组选定的兴趣点（POI）中对每个区域进行评估，这些兴趣点被定义为运输HAZMAT的潜在起点/终点。基于成本函数评估每个POI与潜在区域之间的最短路径，该成本函数可以容纳多个标准以确定每个潜在区域的关联无效性。最后，根据区域的累积无用度得分对区域进行排名。所提出的分析方法是定量的，同时又具有足够的灵活性以允许包含主观标准。以加拿大萨斯喀彻温省为例，证明了所提出方法的应用可以为HAZMAT设施（例如核设施）确定最佳位置。对三种情况进行了评估，其中包括（1）所有网段和POI均得到平等对待，
