Analysing Indicators of Housing in Urban Areas Using a Similar Model to the Fuzzy Ideal Option and Lexicograph Sequential Technique (Case study: Townships of Ardebil Province)

Human settlement mechanism has a fundamental role in the process of historical development of civilization. In this process، cities as the top level of accommodation have been the focus of this role. Cities are author، expander، and engine of development and they act as facilitator of expansion of development and innovation on hinterlands.

In the meanwhile، the study of housing indicators in cities is important because expedite urbanization is accelerating the marginalization and it causes formation of unsafe settlements. Spread out of slum neighborhoods، causing unsightly and undesirable spaces، that the main problem of areas of the city are bad housing and poor health. The increase in poverty، poor access to decent housing and urban services، the emergence of slums and illegal settlements، marginalization and environmental destruction and… has been ravages associated with urbanization. The adverse consequences of low standards of living in urban areas can be in various fields of social (Including increased mass delinquency)، Cultural (including low levels of educational facilities) and physical (including the visual abnormalities). Due to the mentioned fact that on a hand and on the other hand the lack of research using new level modeling and development spatial analysis in Iran in general and Ardabil Province، in particular and also there are the deficiencies in studies communication with a desire range of urban residential areas، such studies look essential and care should be doubled.
