The Desirability Evaluation of Spatial Distribution Urban Facilities In Neighborhoods of Region two Ahvaz Metropolis Using MABAC Model

One of the most important consequences of the rapid growth of urbanization and physical development of the countrychr('39')s cities in recent decades, distribution system is not homogeneous urban centers. Because of the lack of fair access to facilities leading to social crises and   complex spatial problems and distribution will be uneven urban neighborhoods. Therefore, spatial analysis of available facilities at the level of urban neighborhoods, it can lead to the recognition of deficiencies and excessive density and the extent of each of them. The purpose of  the present study, measuring the level of access of residents in the neighborhoods of region 2 of ahvaz metropolis to the required facilities and services, according to four selected indicators of research(Construction, service, regulatory and socio-cultural) and 26 variables have been compiled. Type is of applied research and the research method was survey with emphasis on the questionnaire. The statistical population has been citizenships living in region 2 and relevant experts. Sample size included have been 13 experts and 382 citizens. Method of calculating the sample size using the Cochranchr('39')s formula for citizens and personal estimation method was designed for experts. Kolmogorov-Smirnov(KS)test was used to evaluate the normality of data distribution, and a mean test was used to review the status of research variables. The weighting of variables was also done by the shannon entropy model and ranking of neighborhoods using the MABAC technique. The overall results of the test show the mean; Satisfaction of citizens and experts in neighborhoods: padaafnd hvaaeii, syyed khlaf, zrdosht and kiyan shahr in aspect of selection criteria research(construction, service, regulatory and socio-cultural) is lower than the average number (3) limit  which indicates the poor condition of these indicators in the mentioned neighborhoods. Also, the results of MABAC technique show that, amaniyeh neighborhood Si value (final value of the criteria function of options) equal to1/243 is in the first rank and respectively neighborhoods: kiyan abad, eastern kiyan pars, western kiyan Pars, kiyan shahr, zrdosht, padaafnd hvaaeii and syyed khlaf Si value: 0/481, 0/165, 0/027, -0/024, -0/224, -0/241 and -0/987 is ranked second to eighth.
