Abstract

Extended Abstract Introduction The urbanization increasingly develops in our blue planet. Today’s citizens, in 21st century, experience issues have never been faced before such as environmental pollution, resource depletion, extinction of species, the gap between rich and poor, crime, poverty, bad housing, and etc. However, these serious challenges have destroyed a number of cities or worn out and made non-habitable a part of them. In such circumstances, the value of citizens has decreased and their basic needs are not met. Facing with urban issues, the new theories of urban development such as viable urban with goals including the solving of urban problems, improvement of urban life quality, urban management, leading the city to more efficiency, and respect to local values have got more important. Meanwhile, the identification and understanding of citizens needs (mental demand) and making livable (suitable objective conditions) these settlements may promote the quality of life (mental satisfaction) in urban areas and provide the condition to achieve sustainable development goals. Theoretical bases Selected Livability Persian translations for English words (livability) and thus habitable city of the (livable city) is a (Bondorabad, Yazd, 1390; 49). Webster's dictionary defines viability as a location is suitable for human life. City habitable abstract word and its meaning is very similar to the old adage "Sleeping Beauty in the Eye of the Beholder" is. Therefore, different people, different views of the city are habitable. This approach habitable city, by defining Kasylty (1997) corresponds to the Livability of their living environment defines personal experience.Habitable settlements, is a perfect place to live and work. Livability as a new argument could support the planning and development activities and should be followed by geographers seriously. Secondly, the " Livability of a beginning debate, not only for planners and planners, but also for all citizens who live in the city and citizens rights (not only for people without housing, but also for the working class, middle class, wealthy, for people of color, immigrants, women, etc.) is important.Literature Livability in urban planning and urban development, including the creation of community discussions habitable and safe for the citizens and the requirements it has raised and, increasingly, the concept of community empowerment concept of habitability placed in the first class. Methodology This was an applied descriptive- analytic developmental research. The data were collected through detailed library studies (using documents) and navigation techniques (direct observation, closed questionnaire, and interview). The samples were selected randomly using probability sampling method. In the process of technical computing, HP, and in order to rank and prioritize the strategies set forth in the Swat model of software export Choice has been used. The sample in the priority research strategies, experts and specialists, urban management, urban planning, 30 people are elite and comparing to determine priority based on the questionnaires. Results and discussion Results computing software software Expert Choice; on the priorities for action and the determining of the old fabric of the city habitable volume and area of triangles indicate that the weights in the second quarter was higher than other weight Trigonometry More than any other weight trigonometry and prioritize strategies to the viability of Zanjan aggressive strategy based on the strengths and threats (SO) and gravimetric drive from the origin to the point (SO) is the highest weight value. In this type of strategy is trying to use internal strengths to take advantage of external opportunities. Conclusion Based on the calculations of the factors related to the weaknesses of the "weakness of the hierarchical structure of the network in the tissue level" with weight rating (5.63) as the most important weaknesses in the city's old tissues. As well as monuments registered in the Cultural Heritage Organization certain surface area "with a score by weight (6.29) in the development of distressed areas and the city has the greatest impact on this texture is most important strengths ago. Operating "income opportunities in the region through activation of historical attractions" and a "relatively high economic efficiency of urban plans in the area of the historical background of the range due to convenient location in the city", respectively, with a weight rating (0.168 ) and (0.149) as the first and second opportunities have been identified. At the same time, a "unwillingness to cooperate with neighboring countries for rehabilitation and reconstruction of houses (the assembly)", with the final score (0.176) and a "tendency to focus activities along the main point of access and loss distribution hierarchy public services "with a weight rating (0.167) as the most important threat facing the fabric is worn through.     Keywords: livability, strengthen strategie, old textures, City of Zanjan
