Sustainable Development and Socio- Economic Duality Using Fuzzy System-A Case Study of Iran

Homogeneous development and decreasing of inequalities is a logical link between local and national program in macro level. Recognizing inequalities in the process of sustainable development play the major role for programmers. In this study, regarding the complicated qualification and qualitative of socio-economic indices, Iran provinces were ranked by fuzzy system during 2001-2006. In addition, duality in the concept of gap and differences among provinces were determined using the selected indices. Results showed that although country’s provinces became more homogeneous from the viewpoint of some of sustainable development indices, the distance among several provinces is still high and there is no clear relation among provinces during this study. This study shows that one development program cannot be effective for all areas of a country with socio-economic duality.
