Abstract
Breakdown and maintenance can affect equipment availability, generating delays and increasing the cost of a project. The purpose of this paper is to develop a simulation model to predict equipment availability in earthmoving operations using a High Level Architecture framework. Based on user information, the model can verify the influence of the temperature, quantity of crews, location of breakdown and overheating of the tires on the equipment availability. The user can also define different distributions for maintenance and breakdown intervals, according to the equipment type and model. Different scenarios were defined to verify the model, and the results demonstrated that it can be useful to help inexperienced engineers to verify the influence of several parameters on the equipment availability and provide accurate information to the decision maker.
