Modelo de simulação aplicado à análise operacional de transporte rodoviário: um estudo de caso

Abstract

In a globalized context which competition prevails, the development of logistics flows becomes a requirement based on the search for cost savings and improvements in service levels of customer service. This research is the creation of a computational model of simulation for supporting the decision of operational analysis for road transport hired by the logistics department of ArcelorMittal.The operacional analysis of new flows, that is, the detail and scheduling of road transport activities, merging raw material supply and outflow of product. This analysis is very important for planning and control of vehicles and subsidizes the financial viability of this new flow. Currently, this operational analysis is done on a deterministic, by creating a timeline in a spreadsheet. The timeline it comes to quantifying how many cycles a vehicle is able to perform in a certain flow, in one week. The major objective of the program is to present a new tool, appropriate to the stochastic characteristics of the problem, which could be more precise for the analysis of new logistics flows to be implemented. This would make the necessary information available for the management of the process. Although the program was applied to a specific flow already being implemented, as a case study. However the proposal of the present work is to develop a general model, which could be easily adapted to other analysis. Its results are the quantification of the weekly cycles performed by the trucks, as well as the costs of each model and the earnings by the implementation of the flow in the model of the Central de Tráfego.The computational model was created by the author, in Rockwell Software Arena 11.0.
