Analysis and review of sustainable development in urban areas using multiple criteria decision MADM (case study: city of Kashan)

Introduction Extra development of urbanism dimensions and forming the new scales of urban growth during recent decades causes that contemporary urbanism encounters new challenges. Dimensions'' spread، changes in the nature of urban matters and their intricacy، attention to the different dimensions of the matter in order to permanent solution makes them unavoidable. In this case civic schedulers'' emphasis more than every other time is on the lower levels and touchable dimensions of urban life، in the other word certainty of desirable development is accelerated in city and suburb when the reciprocal effect of these two levels on each other is seen together and after suburb constancy، attainment to urban permanent development is also facilitated. And in fact is trying to find an answer for inconsistency in different scales. Suburbs are places where dimensions of urban matters are absolutely touchable. Constancy of residential places depends on the social، economical and subsistence constancy. Process of permanent development includes economical، social، and environmental asset quality that guides the members to produce and rebuilding the purposeful life. 2-Theoretical bases Development without any hesitation is a valuable concept that is accompanied by manner premises and expresses abstract model of society that accounts desirability، and positive according to valuation and tells the supposed society''s future in the specified time. The most important subject about development is development constancy. Some of the subjects under the study of constant development are directly related to the cities. These subjects include: constant development via planning in land exploitation، city re-revivification، constant buildings، energy and the form of the city، constant transport، contamination and the form of the city. Some of these standards are related to the region level and city parish like family structure، population increase or displacement and movement، subsistence subjects and about skeleton dimensions and life quality indicators there are services and equipments، access to the office، housing quality، changes in transport systems and its effect on the communication networks foundation، form of the passageway network، different methods of construction and exerting urbanism rules. 3-Research founds In this research by using three social- cultural components including: security، identity، and feeling of dependence and six welfare- economical components including: access to the region services، income level، education level، access to the public transportation، access to the communication network and land price in urban area and finally five skeleton- subsistence components including: greenery in area، population accumulation، buildings accumulation، size of the residential parts and custody of environment are checked and in order to attain this purpose they use a combination of Entropy weighting factor coefficient and SAR method. That is at first findings related to each of the components mentioned at the suburbs level of the Kashan city are obtained، then by using Entropy method allocated specified weight to each of thirteen components and finally by using SAR model the amount of constancy at tenfold suburbs level of Kashan city are obtained. 4-Conclusion Research findings results shows that the higher constancy level with coefficient Vat=2. 80 is for area number 10 and the lower constancy level with coefficient Vat=5. 61 is for area number 8. In fact in Kashan''s area number 10 constancy levels is higher than other areas because of access to the public transportation، instruction and hygienic centers and more antiquity and genuineness because it is placed nearby the Kashan''s bazaar and area number 8 has lower constancy level because it is far from city center، inconsistency of population extra growth and their needs، lack of entertainments and low income level. 5-Suggestions Based on the results of the research، for improving constancy level in Kashan suburbs level، and also creating liveliness and happiness in this city، these are suggested:  Increasing greenery، leisure times، and city parks and considering additional free spaces for creating public entertainment centers in suburbs.  Creating educational، cultural- entertainment possibilities and spaces in transient and half-constant areas.  Programming for increasing the economical level of people in lower areas.  Programming for decreasing rate of unemployment and supporting responsibility.  Expansion and suitable planning for roads and tight and narrow passages and destructive houses and increasing connection network level in old parts of the city.  Considering social problems and secure public places، specially parks and entertainment spaces in suburbs.
