Stream methods of work during the construction of a group of construction projects provide the selection of priorities in the optimization of calendar plans. This can be a reduction in the duration of construction or resource provision in time. Due to the change in the arrangement of objects in the stream, the total duration of the work on the entire object complex can be changed. By the methods of organizational and technological modeling, a rational sequence of work is selected taking into account the optimization of resource costs. When constructing a complex of objects, a comparative analysis of various combinations of grouping objects, using the methods of decomposition and aggregation, allows you to carry out a numerical rating of various parameters of the work, such as duration, labor, providing material and technical resources, etc. This ensures the optimal ratio between the duration of the construction of the object complex and additional costs that arise during the parallel construction of several objects. A graphical interpretation of the choice of the optimal organizational and technological solution is work schedules at the facilities, allowing differentially and integrally to evaluate the development of material and technical resources.
