امروزه در بهبود محيط زيست شهري همچون نوسازي بافتهاي فرسوده ضرورت بهره‌برداري از آموزهها و تجارب گذشته با استفاده از مدلها، به ويژه مدلي مفهومي كه از نظريه‌اي بومي استفاده كرده و با شرايط زمينه‌اي كشور ما سازگاري داشته باشد، ضروريست. لذا اين پژوهش چارچوب خود را بر مبناي فرايندي نوين براي دستيابي به تغييرات مثبت در نوسازي بافتهاي فرسوده قرار داده است. در اين مقاله ابتدا نظريه "نوسازي متوازن بافتهاي فرسوده شهري" تبيين گشته و از آن در نمونه موردي(بافت فرسوده مركزي شهر زنجان) استفاده مي‌شود. نتايج حاصل شده از گام نخست، براي استفاده در "مدل‌سازي دايناميكي سيستم بافت فرسوده" مورد استفاده قرار مي‌گيرد. متغيرهاي پژوهش كه براي استفاده در مدل‌سازي استفاده مي‌شوند، شامل تعداد فراوان شاخصها، مؤلفهها و عناصر كالبدي بافت فرسوده شهري مي‌باشند كه از منابع معتبر نظري و مطالعات ميداني و پرسشنامه و نيز استفاده از نظر نخبگان به روش دلفي، به دست مي‌آيند و در نهايت با استفاده از روش تحليل عاملي، به شاخصهاي مهم و تأثيرگذار كاهش مي‌يابند. پژوهش حاضر از حيث هدف، كاربردي و از حيث روش، پيمايشي محسوب مي‌شود. جامعه آماري اين پژوهش ساكنين و استفاده كنندگان از بافت فرسوده مركزي شهر زنجان مي‌باشند كه 375 نفر از شهروندان به عنوان جامعه نمونه به صورت نمونه‌گيري تصادفي انتخاب شدند. نتايج اين پژوهش در "مدل نوسازي متوازن" نشان مي‌دهد كه بافت فرسوده مركزي زنجان، در بعد كالبدي، از توازن خارج گشته و اولويتهاي اقدام براي به توازن رسانيدن بافت را مشخص مي‌نمايند. خروجي "مدل سيستم دايناميك نرم‌افزار ونسيم" نيز از رو به نامتوازن بودن سيستم بافت فرسوده در آينده حكايت دارد. همچنين مدلهاي سيستم دايناميك، صحت نتايج نظريه متوازن را تأييد مي‌كند.

Today, it is critical to apply the teachings and experiences of the past by using the models, especially a conceptual model making use of a local theory being compatible with the context of our country in order to improve the urban environment, such as renovating urban decay. Therefore, this research based its framework on a new process to achieve positive changes in rejuvenating decay areas. In this article, the "Balanced Renovation of Urban Decay" Theory was first explained and it was used in a case study (central urban decayed tissue of Zanjan). The results of the first step were used for "dynamic modeling of decayed networks". The research variables used for modeling included a large number of indicators, components and social elements of the urban decay, resulting from valid theoretical sources and field studies, questionnaires, as well as using the experts’ opinions through Delphi method. This is while they are finally reduced to important and effective indicators using factor analysis method. The present study was applied in terms of objective and a survey in terms of methodology. The statistical population of this study consisted of the residents and users of the decay central part of Zanjan, i.e., 375 citizens selected as the sample population by random sampling. The findings of this study in the "Balanced Renovation Model" suggested that the urban decay of central Zanjan was out of balance from a social dimension and the priorities for action to balance the area were determined. The output of the "Dynamic Software System Model" also indicated that system will be moving in an unbalanced direction in the future. Dynamic system models also confirm the accuracy of Balanced Theory results.
