Complex flows (CFC, CFA, СFP) are calculated using the critical method. A comparative analysis of the methods of complex flows was made, which showed that the CFC and CFP have the shortest duration of the overhaul of the facades of three objects, which is 131 days. Based on a comparison of the options for calculating complex flows by different methods, we can conclude that the CFP method is the most suitable, because the duration of the overhaul is the shortest. CFP is the traditional and most optimal method that ensures the minimum duration of the whole complex of works and is widely used at the present time.

This article analyzes two systems of logistics for construction organizations based on the concept of Material Requirements Planning (MRP) and Just-in-Time (JIT). The main advantages and disadvantages of each system were investigated, and which of them are most effective in the current conditions were determined. Possible options for improving MTO systems are considered, as well as recommendations for the introduction of MRP and JIT into the practice of construction organizations to increase efficiency and reduce costs are proposed. The article will be useful for specialists in the field of construction and logistics, as well as for everyone who works in the field of management and optimization of business processes.

The article is devoted to solving the problems of choosing a variant of the calendar plan in the complex development of residential microdistricts. At present, a methodology for linking construction and installation works in time and space is being developed, new methods for calculating the organization of work are emerging. Due to the constant change in regulatory requirements in construction, the essential characteristics of scheduling methods change. Variant analysis may include a sufficiently large number of indicators of the quality of the organization of complex development. Therefore, a method for comparing options and choosing the best one is proposed, which takes into account an unlimited number of indicators of the quality of work organization.  At the same time, different indicators can be taken into account for different regions, as well as new ones can be added. The effectiveness of the methodology is analyzed on the example of a residential area.
