مکان گزینی مناسب بیمارستان های شهری با استفاده از تکنیک های تلفیقی مدل تحلیلی تصمیم‌گیری چند معیاره و تحلیل های فضایی سیستم اطلاعات جغرافیایی (مطالعه موردی: منطقه 7 شهر تهران)

  Background: In Iran, the rapid growth of urbanization is in a way that it fits into the appropriate location for urban spaces are not switching. The main consequence of this is failure of service delivery and service system to citizens. One of the most important public services that hospitals provide most of the citizens' health. The purpose of this study, “Optimal locating of hospitals in region 7 in Tehran city”.   Material and methods: This research is descriptive - analytical study has been done. For collecting information and data is used field studies and According to information obtained, To review the study area in terms of access to communication road, green space, away from industrial centers, military, and the fault, as well as for weighting the criteria, is used the AHP model. Then, using a decision model of TOPSIS in GIS software, valuation of criteria has been studied and appropriate maps is prepared, finally map that represents the best location for the construction of hospitals in this area is extracted.   Results: with combination and overlaying of data layers, the final map was obtained and determined that the northeastern section (Cross Resalat Street and cabli), central (martyr Motahari streets and Miremad) and southeast (Bakhshi fard and part of Damavand street) in district 7 are have priority and more points to construct hospitals.   Conclusion : System of Multi Criteria Decision Making (MCDM) with GIS can be used as effective tool in site selection of hospitals. Being located of hospitals, near to green spaces and comunication road and its distance from the industrial and military areas as well as the fault, capability of this model in this study is prove.
