summary:Earth moving operations can be represented as Discrete Events Systems (DES), which propitiates qualitative and quantitative analysis. In this paper we propose a model using Stochastic Colored Petri Nets to represent the operational dynamics of earth moving work. For this purpose, a graphic and analytic model that represents the earth moving activities was idealized. Data were collected concerning a real case, followed by several simulations aiming at the economic assessment of the identified operational scenarios. As a conclusion of the study, it can be stated that Petri nets models provide an important instrument for decision makers when managing earth moving planning and execution.
