“…Multiple qualitative factors must be considered when selecting emergency shelters, and candidate sites should avoid areas of potential risks. Topography, geological type, and slope are important factors to be considered when planning shelter location [7,[30][31][32][33]. Shelters are better protected from secondary disasters, such as floods and landslides on the plain than on the hills.…”

Natural disasters can cause serious casualties and economic losses, and emergency shelters are effective measures to reduce disaster risks and protect lives. At present, the location models of refuge facilities often ignore the diversion of shelter from the perspective of humanitarian logistics and the needs of victims. Such models also seldom consider the impact of the pre-storage of relief materials on the location of shelters. In this study, on the basis of the different needs of disaster victims, shelters are divided into two types—basic life and psychological medical service guarantees. While considering the full coverage of shelter needs, capacities, and budget constraints, the shelter distance, the optimized distribution of refugees, and the pre-stock quantity of goods are optimized. The facility service quality is optimized on the basis of qualitative factors. This study proposes a multi-standard constrained site selection model to optimize the pre-disaster shelter site-allocation problem. The model is helpful for decision makers to influence shelter siting and victims’ allocating process through their expertise and to obtain a solution that compromises multiple objectives. In this study, several basic cases are generated from the actual data of certain areas in Sichuan Province, a disaster-prone region in China, to verify the effectiveness of the model.

“…Bayram et al (2018) [38] proposed a scenario-based two-stage stochastic evacuation planning model that optimally locates shelter sites and assigns evacuees to nearest shelters and to shortest paths within a tolerance degree to minimize the expected total evacuation time in Turkey. Xu et al (2016) [39] proposed a multi-criteria constraint location model to select and analyze the candidate for emergency shelters, and to determine the location of new ones while using GIS in China.…”

Japan is exposed to several natural phenomena; the damages caused by earthquakes were enormous in particular. An emergency shelter is a place for people to temporarily live when they cannot remain in their previous homes, and it is necessary for each community to, respectively, allocate such facilities in Japan. There are the districts that are short of such facilities, especially in rural and suburban areas, because emergency shelters mainly concentrate near large-scale stations and city centres in Japan. Against these backdrops, using geographic information systems (GIS), an applied statistical method and public open data related to population and emergency shelters, the present research aims to quantitatively conduct a suitability analysis for the emergency shelters allocation after an earthquake in Japan. Based on the results, the present research grasps the districts that are short of emergency shelters, and visually shows the places where such facilities should be newly established on the digital map of GIS. Additionally, the assessment method is reproducible in the spatial and temporal dimension. It is necessary to create an original data related to emergency shelters to raise the reliability of the results, as the present research has the limitation of data availability.

“…Many researchers also have done some studies about how people should be evacuated during disaster in order to minimize travel time or clearance time. In mathematical form, facility location model also has been used widely for selecting evacuation facilities (Kongsomsaksakul et al, 2005;Li et al, 2012;Xu et al, 2016). Several models and algorithms have been developed to clarify evacuation processes into macroscopic models and microscopic models.…”

Natural phenomena may lead to a huge disaster that is affected by triggering phenomenon and the following phenomena that occured afterward. Nevertheless, following single scenario of disaster to create a disaster emergency plan might lead to an incomparable estimation of risk. The decision maker could reduce the risk and perform an efficient evacuation, By understanding disaster prone area based on hazard assessment. This study proposed a multi-period shelter selection and relocation by considering possible impact due to cascading effect and secondary disaster. The objective was to minimize the cost associated with transport and relocation shelter during the evacuation process. A simple yet powerful Simulated Annealing was proposed to solve the model. This study compared the cost that occurred based on two approaches, hazard assessment map, and radius based map. The result showed that model with hazard map generated a better result in comparison with radius based map. Hazard map could offer different subsets of the shelters identified in the first stage to be selected, thereby producing a minimum number of evacuees.
