Investigating process-oriented urban design models andits role in improving interventions in urban centers

The city centers which are a cultural symbol of cities and towns, are one of the most important public areas in urban spaces. Disregard for urban centers during the rapid growth of urbanization, these centers have faced numerous problems that have reduced the quality of life in them. the present study has been conducted to evaluate the two theories of urban design and fuzzy logic to provide an appropriate model for intervention in urban centers. A model that, the most important principle of this, is the process-centered and the possibility of going back along the path of its design and implementation. Steps to do this research, in order to achieve a proper model with the physical and social characteristics of urban centers, includes several main steps. Firstly, with the help of theoretical studies and experiences of interventions in urban centers, the general principles for intervention in urban historical-social centers are defined. Subsequently, in the second phase, the major intervention theories were study and compared with the process view. The third stage is dedicated, to defining a model that complies with the principles of intervention, which is based on theoretical studies and process-centered theories of intervention, after that, the model was finalized at the end. The results of this research will indicate this, that with the help of process oriented urban design, it is possible to increase the quality of intervention in urban spaces and thus the satisfaction of the operators and moderate negative results of intervention.
