Optimal Location of Rescue Centers Using GIS and Multi-criteria Decision Making Methods (Case Study: Urmia City)

Journal of Rescue and Relief, 2020

INTRODUCTION: Pre-crisis planning is one of the important issues facing managers and planners, especially in the field of crisis management. In recent years, the world has faced an increasing number of natural and man-made disasters, such as earthquakes. Moreover, the growing effect of disasters on communities has highlighted the need for efficient and effective emergency logistics operations in this field, and some criteria are provided for decision-making and prioritization of relief centers in crisis situations. METHODS: In the current research, Analytic Network Process (ANP) and PROMETHEE (Preference Ranking Organization Method for Enriching Evaluations) methods were used for analysis and ranking, and construction cost and usage time indicators were considered for the first time. Criteria were also defined and evaluated as layers according to global standards and crisis management criteria in the region. In addition, geographic information systems and expertschr('39') op...

A Multi-Objective Optimization Model for Relief Facility Location in Crisis Conditions

2021

This research was conducted to study the issue of relief facility location hierarchically by consideration of possible road closure during the crisis conditions, road safety, and arrival time of relief facilities under disaster circumstances. High costs are allocated for facilities deployment in a suitable location to meet the demands of injured people. Therefore, location-allocation of emergency facility should be considered in a way to use them for long-term periods. To this end, the extant research designed a multi-objective optimization model to minimize the pre-disaster costs including costs of facilities deployment and road use, and to minimize the post-disaster costs such as cost transportation in-network roads. Moreover, the innovative part of the studied model in this research examined the road safety and reduction in time taken to have critical facilities in affected areas. To investigate the functional accuracy of the mathematical model, a numerical example with small dimensions was solved using CPLEX Solver, and required sensitivity analysis was described. As the facility location-allocation is an NP-hard issue, two meta-heuristic algorithms were used to solve numerical representations in real dimensions to examine numerical analyses effectively. Results showed that the dragonfly algorithm had the highest efficiency compared to other developed algorithms. The obtained results can be considered as an efficient managerial tool in management organizations involved in the crisis.

Efficient Crisis Management by Selection and Analysis of Relief Centers in Disaster Integrating GIS and Multicriteria Decision Methods: A Case Study of Tehran

2021

In Iran, location is usually done by temporary relief organizations without considering the necessary standards or conditions. The inappropriate and unscientific location may have led to another catastrophe, even far greater than the initial tragedy. In this study, the proposed locations of crisis management in the region and the optimal points proposed by the Geographic Information System (GIS), taking into account the opinions of experts and without the opinion of experts, were evaluated according to 18 criteria. First, the optimal areas have been evaluated according to standard criteria extracted by GIS and the intended locations of the region for accommodation in times of crisis. Then, the position of each place is calculated concerning each criterion. The resulting matrix of optimal options was qualitatively entered into the Preference Ranking Organization Method for Evaluation (PROMETHEE) for analysis. The triangular fuzzy aggregation method for weighting and standard classifi...
