A stochastic colored Petri net model to allocate equipments for earth moving operations

Abstract

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.
