本研究以日本关东地区地震为例，重点研究灾前阶段的配送中心选择问题。本研究旨在实现两个目标，一是通过层次分析法（AHP）确定影响数据中心选择的标准的重要性，二是基于加权总和产品评估（WASPAS）和k-means对现有私有数据中心进行排名，并评估其选址趋势和利用情况。结果表明，与最近公路的距离、建筑面积和建成区面积是选择数据中心的重要标准。此外，排名靠前的数据中心位于神奈川和千叶。应优先考虑位于机场和港口附近的DCs。但是，对于远离机场和港口的地区，最重要的是利用靠近高速公路且面积大的DCs。
In this study, we focus on selecting distribution centers (DCs) in the pre-disaster period based on the case of an earthquake in the Kanto district of Japan. This research aims to achieve two objectives, (first) to define the importance of criteria that impact the selection of DCs by analytic hierarchy process (AHP), and (second) to rank existing private DCs and evaluate their location tendency and utilization based on weighted aggregated sum product assessment (WASPAS) andk-means. The results show that the criteria of distance to the nearest highway, floor area, and built-up area are essential for selecting DCs. Furthermore, the top-ranked DCs are located in Kanagawa and Chiba. DCs located near airports and ports should be prioritized. However, for regions far from airports and ports, it is crucial to utilize DCs that are close to highways and have large areas.
