عنوان مقاله [English]
To survey of Islamic cities from birth of Islam until Qajar era in Iran ,some differences are unfolded ,one of these differences is dynamism that is a main difference between past Islamic urban spaces and contemporary urban space that is generated via organized complexity . This complexity is occurred in an open system(is a system which continuously interacts with its environment. The interaction can take the form of information, energy, or material transfers into or out of the system boundary, depending on the discipline which defines the concept) with fractal members(mathematical set that has a fractal dimension that usually exceeds its topological dimensionand may fall between the integers. Fractals are typically self-similar patterns, where self-similar means they are "the same from near as from far) that Fuzzy logic(is a form of many-valued logic or probabilistic logic; it deals with reasoning that is approximate rather than fixed and exact.) controls members behavior without any exterior power. so because of reaching unity in chaos urban space , all components have deep structure and motion to one target with feedback process ,and because of following this procedure, endogenous development arise and dynamism emerges in system.
In other hand, people cooperation has important role in this process that is basic principle of sustainable urban design .
Since the beginning of human history, the geometric order and fractal geometry (a dominant geometry in nature that define the disordered shapes) exists in the architectural and urban structures together. In context of follow dissertation, this paper presents an opinion, that for a good quality of architectural space, the balance between order and chaos is necessary. The architectonic space is created by design and other self- organising processes as well. In the long term it is unforeseeable and unstable. The development of the chaos theory,) is a field of study in mathematics, with applications in several disciplines including physics, engineering, economics, biology, and philosophy. Chaos theory studies the behavior of dynamical systems( creates a new perspective for better understanding of chaos and complex processes in architecture. Some aspects of this theory can by applied in design
The present work is a limited analysis of the traditional urban fabric of Muslim cities in the light of this theory. Chaos theory provides better instruments for the analysis and understanding of the traditional urban fabric in old Muslim cities that have, paradoxically, long been considered as lacking order and thus “chaotic” in the pejorative sense! Beyond the analysis, our study also aims at providing a fresh approach to the built environment that shifts the architectural and planning professions from the traditional design and planning approach to a self-generating process that, once set up, would function and develop without need for intervention. However, the present study will be limited to the application of such concepts at two levels. At the urban level, it will provide evidence of the existence of chaos and fractals at the scale of the city. At the domestic level, concepts are applied to housing evolution and community spaces.
