Optimization of construction schedule on the criterion of inequality in the distribution of labor forces

Being one of the technical and economic indicators of construction schedule, the coefficient of inequality in the distribution of labor forces (coefficient of uneven labor movement) kun reflects the distribution of labor forces over time, is responsible for the optimization and regulation of construction period, is the basis for calculating the number of temporary buildings on a construction site, followed by the need for space for these buildings at a construction site. The problem resides in the absence in the publicly available sources of substantiated data on the values of this coefficient and regulatory requirements for its limitation and calculation. To solve this problem, a new method for determining the maximum value of kun based on the projected or required duration of the steady-state flow in the flow line manufacturing is proposed. For this, mathematical modelling of multiple variants of labor movement diagrams is carried out while fixing the values of duration and labor intensity. This variant modelling makes it possible to obtain the dependence of kun on the steady-state flow time. The mathematical dependence for assigning the limiting kun within the time of the steady-state flow equal to from 25 to 100 % of the total duration of the work is determined, which allows dynamically changing kun depending on the specific conditions for the design of the construction schedule and the general organization and management of the construction project.
