Location Analysis of Regional Disaster Relief Material Reserve Center: A Case Study in Sichuan Province, China

Abstract

The disaster relief material reserve center is an important strategy to deal with natural disasters. Aiming at its location problem, this paper first constructs a site selection decision evaluation system from five aspects: nature, transportation, infrastructure, social benefits and economy. Secondly, the fuzzy matter element analysis and gray TOPSIS (Technique for order preference by similarity to ideal solution) method are used to construct the disaster relief material reserve center location measurement model. Finally, an empirical analysis is carried out in Sichuan Province. The results show that the Sichuan-Central region is the best place to build a disaster relief material reserve center in Sichuan Province. This model can not only effectively locate the disaster relief reserve center, but also provide a new idea for solving the problem of multi-dimensional influencing factors.
