Quantitative spectrum the urban vulnerability of against earthquake ‎(Case study of Yazd city)‎

One of the topics of interest to urban planners issue "safety planning" cities is that one of the most basic assumptions of the international community for human-centered planning. Reducing vulnerability to natural hazards analysis and critical areas and wide in the sphere of planning and crisis management has become. The need for this study using spatial statistics simulation Bootstrap and COPRAS to the issue of urban vulnerability (VI) in the city of Yazd. The study has a developmental approach – Applications And a combination of research methods (library, athletics and analytical - descriptive). As well as the analysis of data from applications EQS, PLS, Grafer, Excel and GIS have been used. The results show that in the area of the vulnerability of building physical variables - variable frame buildings with an area of 100 to 200 square meters not have any distribution and dispersion. They suggest that the vulnerability of mean index in the urban of Yazd The variables of living in social vulnerability lowest coefficient of dispersion and habitat variables included in the group. The results are weighted in relation to the areas with the use of simulators have gained more confidence. As the city of Yazd using BootStrap gained confidence 95/0. And the results of the three regions COPRAS techniques that amount, respectively, in 0/85, 0/0, and 87/0% As the number two, three and one Vulnerability (SoVI & SBVI) are located.
