An overview of modern publications on the logistics of construction operations is presented. Practice of organizing the provision of construction facilities with material resources requires the coordination of their supply and consumption processes. It is essential in the organization of logistics to determine the required volume of supplies and their distribution over time. In conditions of non-stationary demand, the Wagner-Whitin procedure is proposed. The total costs for the entire planning period are taken as the target function. The proof of optimality is based on the formal interpretation of the concave programming problem. The optimal solution is achieved when the supply volumes coincide with the total volume of the specified schedule of construction and installation works for several consecutive planning periods. The choice of optimal supply volumes is reduced to sorting through a finite number of possible options for splitting the planning period into segments, each of which requires construction flows from the same supply. The dynamic programming method is used to organize the search. The proven recurring ratio made it possible to reduce the quantity of estimation iterations to find the minimum cost for the planning period and the appropriate optimal delivery schedule. The developed calculation algorithm is demonstrated using a numerical example. The method presented by the authors allows solving the problem of optimizing the delivery schedule of material resources, increasing the uniformity of construction flows, and reducing the amount of working capital in construction.
