This article introduces a framework for the multi-criteria satisfaction assessment of the spatial distribution of urban emergency shelters.A GIS-based analytic hierarchy process approach was utilized to conduct the assessment based on selected criteria layers for daytime and nighttime scenarios,respectively.The layers were generated from high-precision land use data based on highresolution aerial images and census data.Considering the uncertainty in criteria weighting,a spatial sensitivity analysis was undertaken for deriving more accurate results.The feasibility of the framework was tested on a case study in Jing’an District,Shanghai,China.The assessment results show that both at nighttime and during daytime,even if all potentially available shelters are open,the demand in large areas can only be marginally satisfied or not satisfied,especially in the northern,eastern,and central parts of Jing’an District.The quantitative analysis of the satisfaction conditions of the buildings or land parcels and the affected people,especially children and the elderly,shows a low satisfaction level of shelter services in these areas.The satisfaction assessment of emergency shelters can help government decision makers find low satisfaction areas of sheltering services and support further locationallocation optimization of urban emergency shelters.
This article introduces a framework for the multi-criteria satisfaction assessment of the spatial distribution of urban emergency shelters. A GIS-based analytic hierarchy process approach was utilized to conduct the assessment based on selected criteria layers for daytime and nighttime scenarios, respectively. were generated from high-precision land use data based on highresolution aerial images and census data. Consumption of the uncertainty in criteria weighting, a spatial sensitivity analysis was undertaken for deriving more accurate results. The feasibility of the framework was tested on a case study in Jing ’an District, Shanghai, China. The assessment results show both both nighttime and during daytime, even if all potentially available shelters are open, the demand in large areas can only be marginally satisfied or not satisfied, especially in the northern, eastern, and central parts of Jing’an District. The quantitative analysis of the conditions of the buildings or lan d parcels and the affected people, especially children and the elderly, shows a low rating of shelter services in these areas. prestige assessment of emergency shelters can help government decision makers find low say areas of sheltering services and support further locationallocation optimization of urban emergency shelters.
