Title
A STOCHASTIC COLORED PETRI NET MODEL TO ALLOCATE EQUIPMENTS FOR EARTH MOVING OPERATIONS
Abstract
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. The objective of the work reported in this paper was to create a model based on stochastic colored Petri nets that is capable of providing adequate understanding of the operational dynamics involving teams of loader and truck, which are employed in earth moving processes, as well as enabling the simulation of auxiliary operational scena- rios involved in construction planning. The structure of the paper comprises five sections. In the first section, the research subject is introduced. In the second section, the basic definitions about earth moving are presented, considering the dimensioning of mecha- nical teams and the mathematical model put into effect. In the third section, the stochastic colored Petri nets are outlined. In the fourth section, the proposed model is described and put into effect, and the achieved results are shown. Finally, in the fifth section, conclusions of the work done are presented.
