The problem of determining the minimum required sufficient amount of material resources reserves to ensure the continuity of construction and installation works has been solved in the article. The review of modern publications on determining the level of the current stock of material resources of construction production is presented. The practice of material resources organization of construction objects requires coordination of the processes of their supply and consumption. The probabilistic nature of material and technical supply of building production complicates the use of methods for determining the reserves based on the use of average values. The deviation of the average delivery interval from the planned one, as well as the standard deviation do not allow determining the size of the reserve, as they do not take into account conformity of the total volume of deliveries to the demands in the given type of material resources. To adequately reflect the dynamics of consumption and material resources supply, it is proposed to use the method of statistical modeling. Application of the statistical modeling method implies establishing the nature of random values distribution of the elements of material and technical support—intensity of supply and consumption volumes, intervals of supply and consumption. The work with the model consists in changing the input parameters and evaluating the behavior of the system according to the criterion adopted. The criterion for selecting the optimal inventory level is the minimum value of the costs associated with storage and downtime of construction crews during the planned calendar period. The choice of the optimal size of the stockpile is reduced to the calculation of costs depending on the size of the initial stockpile. The developed calculation algorithm is demonstrated by a numerical example. The method presented by the authors allows solving the problem of optimizing the size of the material resources production stock, increasing the uniformity of supply of complex and specialized teams’ workers, reducing the amount of circulating assets in construction.
