Abstract

Site selection for sitting of urban facilities is one of the crucial policy-related decisions taken by urban planners and policy makers. The combination of GIS with fuzzy set theory and deterministic models is known as GIS Fuzzy Modeling (GISFM). GISFM was adopted for support sustainable land use planning. This paper considers the specific problem of creating a well-sustainable distributed of hospitals. We develop a Multi-Criteria Decision Analysis process that combines Geographical Information System (GIS) analysis with the Fuzzy Analytical Hierarchy Process (FAHP), and use this process to determine the optimum site for a new hospital in Aswan City. Based on actual conditions of the study area, we built a hierarchy model for selecting optimum health care services sites in Aswan city, Egypt. We considered two main factors, and 5 sub-factors. An application adopting the AHP idea was developed to calculate weights of the criteria of the site. The GIS was used to overlay and generate criteria maps and suitability map. The (GIS) was used to manipulate and present spatial data. All maps are graded from 1 (lowest suitability) to 5 (highest suitability) using spatial information technologies. The candidate sites were determined by aggregation based on the criteria weights. The candidate sites are divided by ‘best’, ‘good’ and ‘unsuitable’ landfill areas. Best health care site represent optimal sites; good health care site can be used as back-up candidate sites. Our work offers a siting methodology and provides essential support for decision-makers in the assessment of health care site management problems in Aswan City and other rapidly developing cities in developing countries.
