Abstract

Based on the reporting and technical documentation and for the objects under consideration, the authors were able to form resource schedules that reflect the planned and actual values of the labor force for certain time periods. After analyzing the available statistics in terms of the activities of the leading production stream, a number of graphs were compiled showing the movement of these teams at the facilities. Based on these data, the authors determined the average deviation of the actual number of workers in the leading stream from the planned one. Also, the availability of operational information from these objects made it possible to determine the consequences of deviations and a set of measures taken. As a result, the authors analyzed the dynamics of construction of typical facilities of different general contracting organizations, taking into account the scale factor (capacity of the construction organization) , indicating the difference in the values of the planned (predicted) and actual labor resources at the facilities. Possible solutions of this problem with the mathematical modeling of stable labor force distribution system at sites followed by a possible optimization of the objective function on limitations have been determined. Safe corridors of fluctuations in the values of the labor force, as well as the fundamental foundations of the optimization method, have been also determined.
