A location-routing model on relief distribution centers

Abstract

There have been many unexpected natural disasters such as earthquake, flood, etc. in developing countries, which have created catastrophic incidents and we need to do appropriate planning for relief to reduce the possible casualties. Such actions normally face different challenges such as damages on transportation infrastructures including roads, bridges, etc. One of the primary actions for such crises management is associated with facility location for relief distribution centers. This paper presents a multi-objective mathematical problem and applies it for a real-world case study in northern region of Iran. The study uses Lp metric to handle different objectives and fuzzy programming is used to cope with uncertainty. The preliminary results indicate that the proposed study of this paper has been able to provide efficient results.Growing Science Ltd. All rights reserved. 6

A Modeling Framework of Hierarchical Earthquake Relief Center Locations Under Demand Uncertainty

“…In recent years, many studies have been carried out related to earthquake relief center according to location-allocation problem. The various parameters were considered in the model developments for solving the problems, such as time, cost, distance, demands, uncertainties, and etc [16][17][18][19][20][21][22][23][24][25][26][27]. The uncertain parameters were used in the analysis based on the unpredictability of earthquake, which include demand supply cost and etc.…”

“…The uncertain parameters were used in the analysis based on the unpredictability of earthquake, which include demand supply cost and etc. The objective functions that used in the problems were devided into into three types: 1) Total cost, such as facility cost, transportation cost, shortage cost, loss cost, inventory cost, and operation cost [16][17][18][19][20][21]; 2) Total time, such as travel time, relife distribution rate, and resource allocation time [22][23][24][25][26], and 3) Total demands [27]. However, most research used total time to determine the locations of earthquake relief center because limitation of initial response after earthquake that should be received within the "golden 72 hours" [28].…”
