Measuring and Evaluating of Urban livability Components whith Using Environmental Indicators Approach Based on MCDM Techniques Case Study:Triple neighborhoods Ahwaz Metropolis

this research is to Measuring and Evaluating of Urban livability Components whith Using Environmental Indicators Approach Based on MCDM Techniques in Triple neighborhoods Ahwaz Metropolis. is descriptive-analytic in terms of method and nature, and in terms of purpose it is an applied research. Also, data collection and required data for research were carried out in two waysdocumentary and survey. Then, the data were analyzed in the first stage by SPSS software, so that the reliability of the research tool was tested by Cronbach's alpha, which is 0.882, indicating a high level of reliability of the questionnaire, and using the ANOVA test and the Tukey and Scheffe test, urban livability status was measured using environmental sub-indicators. Subsequently, it was entered in the EXCEL software environment and using the multi-criteria decision making models of VIKOR, ELECTRE, SAW, and the caplend integration model, three areas In terms of Urban livability with Emphasis on environmental Indicators ranking and prioritizing them. The final results of the research showed that based on the capland model, the Kianpars neighborhood has the highest priority as the environmental indicator of urban livability, and then Golestan and Sepidar neighborhoods were placed in the next priorities. Also, the integration of sub-indices of neighborhoods and the proportional coefficient of the three neighborhoods in Copland integration model showed that the Kianpars neighborhood in terms of urban livability with an environmental index approach in the suitable conditions, the Golestan neighborhood is in some degree suitable and the Sepidar neighborhood is in not suitable condition.
