On the Issue of Choice of the Most Rational Combination of Earth-Moving and Transport Equipment in Earthwork Production

Purpose: Analysis of the problem choosing optimal set machines in building transport construction facilities. The equipment rational combination choice earthmoving sets is always relevant. Construction process productivity, time, labor costs, production costs and many other indicators efficiency depend on how rationally chosen machine sets. Methods: calculation formulas reliability theory, theory large systems mass service are tool for research analysis issue at facility construction. Since processes, being considered by author, possess all features systems, they dynamic can be probabilistically predictable. Results: article proposes options earth-moving "excavator - dump trucks" relation to with having different technical parameters ranges soil transportation. presented variants obtained using mathematical apparatus theories. Practical significance: results, authors, proposed easy-to-use tabular form have practical significance, since if used organizations, capable increase productivity reduce time.
