The paper analyzes the technological preparation of production at the railcar enterprises in terms of developing technological processes and processing sets of technological documents. Factors affecting the quality of technological preparation of production for maintenance and repair of rolling stock are considered. In contrast to the previously performed works, where the assessment of the level of technological training was carried out by experts of a scientific organization, the initial data in the article were the results of a survey of specialists of technical departments of structural divisions of the car industry of the Sverdlovsk and South Ural Railways. Based on the method of expert qualimetry, the weight of factors that have the greatest impact on the quality of technological processes is estimated. As a result of the survey, a low level of automation of design processes was established, which consists mainly in the design of technological documentation. It is shown that the degree of depth of development and detail of technological processes is at the level of the route description

This paper reports the structure and the analysis of possible solutions for the realization of design procedures complex ensuring the efficient fulfillment of assembly operations on the basis of a tie between the technological preparation of production (TPP) for manufacturing activity and assemblage of high-precision products taking into account requirements taken at designing products. The realization of this approach in SADL-TP is urgent as the complex of design procedures will allow taking into account a real production situation and choosing efficient technological processes for parts machining taking into account assemblage requirements. That, in its turn, will allow decreasing labor-intensiveness, production time and cost price and increasing quality and accuracy of high-precision products, and also reducing time and labor-intensiveness at TPP.

The article is devoted to reengineering of technological processes - a method of their qualitative transformation on an innovative basis, which in turn assumes the availability of tools that make it possible to establish the economic efficiency and technical capability of such transformations of construction production, to identify the effect of their implementation. In this regard, the problem of forming a parametric model of reengineering of construction technological processes, which involves four enlarged groups of indicators that reflect the quantitative and qualitative characteristics of the processes: materials used, working time, machine time, spatial organization, is considered. It is established that parameters can have either an absolute (physical, cost) or relative (point, percentage) expression and also make their own decomposition. The practical significance of the provisions given in the article is determined by the development of methods of technical rationing, which leads to a reduction in the cost and duration of construction.

The success of the Program of housing stock renovation in Moscow depends on the efficiency of resource management. One of the main urban planning documents that determine the nature of the reorganization of residential areas included in the Program of renovation is the territory planning project. The implementation of the planning project is a complex process that has a time point of its beginning and end, and also includes a set of interdependent parallel-sequential activities. From an organizational point of view, it is convenient to use network planning and management methods for project implementation. These methods are based on the construction of network models, including its varieties – a Gantt chart. A special application has been developed to simulate the implementation of planning projects. The article describes the basic principles and elements of modeling. The list of the main implementation parameters of the Program of renovation obtained with the help of the developed software for modeling is presented. The variants of using the results obtained for a comprehensive analysis of the implementation of large-scale urban projects are proposed.
