In recent years, environmental-oriented concepts of sustainable urban development have been actively developing, in particular, in the spheres of energy efficiency and resource conservation in the context of the theory of thrift, smart and environmentally-oriented creation. Four scientific concepts can be distinguished from a set of scientific theories and methodological approaches: industrial metabolism; control «on the pipe»; social and ecological metabolism, thrifty production. In particular, the concept of «lean manufacturing» has shown its effectiveness in practice in many countries in various industries. This concept is environmentally friendly, has a high potential for implementation, but is not sufficiently appreciated by domestic enterprises. Despite its widespread implementation and development, the lack of its implementation at domestic industrial enterprises is explained by the lack of adapted methods and tools for resource conservation management based on this concept. It explains the relevance of the study, which proposes a theoretical and methodological substantiation of the program for a phased transition to «lean manufacturing», which ensures an increase in the efficiency of enterprises in modern conditions, which will increase the sustainability of cities ultimately.

One of the basic values for a person is housing. It provides economic stability, security. In our country, the number of dilapidated and emergency housing is growing at an alarming rate. Developed federal, regional, municipal programs for the overhaul, reconstruction of housing stock at the moment cannot stop the process of growth of such housing, especially in depressed regions of the country. In this regard, the purpose of the study is to develop the theoretical and methodological approach to the development of housing programs in depressed regions (using the example of Volgograd), which will solve the problem of the growth of dilapidated housing. The main methods of research were the methods of modeling, logical, comparative and statistical analysis, analytical information processing and expert assessments, graphical and tabular presentation of information. As a result, in order to automate the operations of evaluating the housing stock for recognizing its dilapidated or emergency, to select and substantiate the type and form of its restoration, the authors developed the "AORV" software product, which allows to increase the accuracy and efficiency of analytical work, the reliability of the results obtained by exclusion of the human factor, to reduce the duration of the recognition procedure. The creation of a department for the restoration of obsolete housing will allow to accumulate all the money for the restoration of obsolete housing, to solve the problem associated with the restoration of such housing, to improve the quality of the housing stock.
