A Hybrid Approach of VIKOR and Bi-Objective Decision Model for Emergency Shelter Location–Allocation to Respond to Earthquakes

Earthquakes have catastrophic effects on the affected population, especially in undeveloped countries or regions. Minimizing impact and consequences of earthquakes involves many decisions disaster relief operations that should be optimized. A critical management problem is to construct shelters with reasonable capacity right locations, allocate evacuees, provide materials them within a period. This study proposes bi-objective hierarchical model two stages, namely, temporary shelter stage short-term stage. The proposed objectives at different stages are minimize evacuation time, maximize suitability based qualitative factors, number sites while considering demand, capacity, utilization, budget constraints. performance evaluation emergency was carried out by fuzzy-VIKOR, most ideal location determined through multiple standards. Emergency organizations can benefit from collective expertise decision-makers because method uses their knowledge automate allocation process shelters. In case Chengdu, Sichuan Province, China, results using this hybrid approach government range options. realize trade-off between efficiency cost material distribution, reliable solutions emergencies.
