| Abstract. | Problem statement. The aim of the work is the optimal picking of construction machines that perform different technological operations for a given process in conditions of complete certainty. Results. In the course of numerical analysis of the optimal picking of construction vehicles, the unit costs of the works are determined. The calculation is based on the dynamic programming method and the optimality principle created by R.E. Bellman. The optimization task is simplified by a local search for the optimal solution, that is, the entire system is divided into parts and for each part a minimum cost value is searched. The calculation algorithm is developed in the computer-aided design system MathCAD. The program allows us to change the source data to calculate any set of machines, according to the selected optimization criterion. Conclusions. The significance of the obtained results lies in the fact that with the optimal picking of construction vehicles, the costs of work are minimized. Due to the calculation using the program, the time for selecting the optimal complex of machines is reduced, the rate of automation of design is increased. |
