A Scenario Approach to Construction Equipment Selection

Purpose: To evaluate the type of construction equipment used in the construction of a railway track embankment with excavator units, taking into account their technical and economic characteristics. To ascertain the the key indicators for the construction equipment selection. To evaluate the variability of the construction equipment components according to the key indicators. Methods: Queuing theory, scenario approach methods, estimation of probability of the equipment failure-free operation. Results: The formulation of scenarios for the construction of equipment has been completed. For all scenarios that were generated, the probabilities of failure-free operation of the equipment, the mathematical expectations of the equipment’s performance and the equipment’s cost have been calculated. Practical significance: The scenarios obtained will serve to simplify and reduce the time required to make a management decision on the selection of the construction equipment.
