This research is related to the inefficient fabric of a city, which has different social, economic, physical and environmental dimensions, and knowing each dimension requires its own method. The main methods in collecting physical data and information are observation and receiving information from relevant bodies and organizations, and questionnaire and interview methods are effective for obtaining social information, as well as documentary and library studies, which provide valuable information in relation to this issue. provides us. Among the common and practical techniques in the quantitative method is the use of questionnaires and in the qualitative method, interview and observation. In getting to know the neighborhood, interviews with key informants, interviews with neighborhood residents, direct observation, questionnaires, as well as physical and field impressions have been used. In relation to documentary information, Fardis city regeneration plan and specialized articles have been used to collect information. The spatial frame in this research is the area of ​​the approved urban inefficient fabric of Fardis city. The statistical population under questioning is made up of the residents of inefficient neighborhoods, which after determining the statistical attribute through the guide sample, the estimation of the sample size is done through the formula of estimating binomial distributions. Sustainable urban regeneration is a complete and integrated approach in evaluating inefficient urban structures. The purpose of this research is strategic planning to investigate and analyze the inefficient and dilapidated parts of Fardis city and to adopt operational methods with system analysis techniques, which is done through the analysis of the mutual influence of economic, social, environmental, physical, managerial and legal factors. Is. The method of data collection was by using observation, interview and data of the organs and organizations of Fardis city, and library and documentary studies were also used. After collecting information using SWOT technique, classified information and situation evaluation indicators were prepared. From the intersection of the final score of the matrix of external factors with the number of 3.24 and the final score of the matrix of internal factors with the number of 3.01, it can be said that the inefficient fabric of Fardis city is in an aggressive position (maximum-maximum). In this situation, for strategic planning, three managerial strategies of cooperative improvement, provision of renovation facilities and local institution building can be used. According to the points given to the effective indicators, the index of physical factors and then social factors have the most points. These three strategies are physical, environmental, social and managerial. The method of collecting physical data and information is to observe and receive information from the relevant bodies and organizations, and to obtain social information, questionnaires and interviews have been used.

Environmental improvement working group, renovation working group and neighborhood social working group with the membership of management institutions and local residents for sustainable participation. With a strategic and systemic view of the problem, the indicators that were counted from the neighborhood were evaluated and weighted, and the SWAT technique was used to establish the mutual relationship between the indicators, and the internal and external conditions of the inefficient tissue were investigated. From the intersection of the final score of the matrix of external factors with the number 3.24 and the final score of the matrix of internal factors with the number 3.01, it can be said that the inefficient structure of Fardis city is in an aggressive position (maximum-maximum). In this approach, the most focus is on the strengths of the neighborhood and external opportunities. Adopting strategies in an aggressive approach are: 1- Participatory improvement 2- Granting renovation facilities 3- Local institution building; According to the points given to the effective indicators, the index of physical factors and then social factors have the most points.
