Abstract
In the construction of infrastructure facilities, earthworks usually represent a large and significant part of the project in terms of quantities and thus costs. Therefore, it is important to make the right selection of machinery to perform these works in order to keep costs as low as possible. The paper presents a simulation model for the selection of a more favorable variant for excavation and transport of soil material. The hybrid approach, a Discrete Event method in combination with Agent Modeling, was used to create the model, and the model was developed in the AnyLogic software package. Based on the data to be entered at the beginning of the simulation, the model calculates the total costs, total duration, as well as unit costs for two combinations of machines that can be used for excavation and transport of soil. Depending on the set criteria, minimum duration or minimum costs, the optimal combination is chosen. The model can also be applied to various analysis by changing the input parameters.
