Considering the emergency resource distribution strategy of zoning and grading under urban emergencies

Complex road networks and road damage and restrictions after emergencies, which increase the difficulty of emergency supply distribution . To address this issue, this article proposes a zoning and grading strategy, different disaster severity classification in different micro-zones correspond to different emergency resource distribution strategy to meet delivery requirements. This article simulates the disaster scenario after a earthquake in Chengdu using Python. DBSCAN is used to cluster resource demand points, and noise points are processed based on the division of traffic zones to obtain reasonable micro-zoning. Next, the fuzzy logic-based evaluation method will be used to grade the disaster situation in the micro-zone, Among them, small and medium-sized adopt a cyclic resource distribution mode, while large and extra large s adopt a 1- 1 distribution mode. Differentiated resource allocation strategies are implemented based on post-disaster zoning and classification results, thereby improving the rationality of transportation in rescue operations and material distribution, as well as enhancing humanitarian considerations.
