Introduction: Identify the vulnerability of residential areas and city zoning and prioritize vulnerabilities in urban areas, can prevent and prepare policies to retrofit residential complexes. The purpose of this paper is to identify and prioritize the vulnerability of housing units in urban areas of Shiraz is based on physical characteristics.
In this paper, we present a multi-objective model with a promising application based on index’s skeleton planning of residential units in the city of Shiraz.
In this descriptive - analytical and applied research, the vulnerability of residential units on the basis of 7 criteria was performed using the analytic hierarchy process for weigh ting the criteria and standards relating to the use of GIS to integrate mapping.
Our findings indicate that design of Shiraz urban planning in line the principles of passive defense has not. So that, the highest vulnerability based on network access roads and open space, related to region 8, and the least vulnerability related to 1 area and 6 is urban. The result to reduce the vulnerability in urban areas of Shiraz, based on the criterion of proximity sensitive centers, zones 4 and 1 in priority scheduling are. Programmed to measure population density, in regions 2, 5, 4 and 8 in Priority are. Measure of openness and substructure housing units in zones 8, 3 and 7, benchmark building density in regions 1, 6, 5, Standard life building residential units and network access in zones 8, 5 and1 priority scheduling are. Whatever from the sidelines city as we get closer to the city core rate vulnerability residential units and more. This is due to sensitive military sites, high population density, low substructure residential units in center of the city.
