The purpose of this work is to implement an on-line control system able to adjust the production in real time applying a simulation model with algorithmic optimization and data transfer for a programmable logic controller. The Solver tool of the Excel software was integrated into a simulation software used to find the optimal dosing of input aggregates in a Hot Mix Asphalt process. Tests were carried out in different scenarios; the results demonstrated that the proposed control was effective, leading to a possible improvement in the quality of the product, enabling it to be kept within the specifications desired for most of the time. Besides, the proposed solution appeared to be simple and accessible for small companies as it applies the Excel software and a free and open-source discrete event simulation software.

“…As commercial software is of high cost for small companies, Ururau is more accessible to assist them as it is a free software that can be accessed at http: //ururau.ucam-campos.br. In addition to the basic models of discrete simulation, this software, currently in version 1.0, also presents other specific modules to calculate emission of CO, optimization and decision by artificial neural network (ANN) as can be seen in the work of Peixoto et al (2016). It is important to emphasize that, in recent literature review about FOSS of DES for operational research, Dagkakis & Heavey (2015) highlighted Ururau as one of the ten main free software of DES between the existing 44.…”

ABSTRACT. This work analyzed different logistics structures under a sustainable perspective. It was developed a discrete event simulation model associated with optimization algorithm to evaluate the best combinations of the model. Besides, the comparison between the simulation optimization and a multicriteria method was performed. The simulation software Ururau, in which a model with optimization algorithm allowed testing different variables, was applied in order to find the best answer to the issue. Results showed that a connection of direct proportionality between variables of transport time, greenhouse gas emissions and lead time can happen. It was also checked that the solution returned by the simulation optimization was similar to the multicriteria method in most of the tests. The ones that differed were due to small mathematical precisions between the methods.

Resumo: O objetivo deste trabalho foi analisar as emissões de gases provenientes das descargas de caminhões durante o transporte de cana-de-açúcar de fontes produtoras para uma determinada usina. Foram investigados cenários alternativos para a movimentação da carga considerando uma variável de desempenho do sistema, tempo de transporte, e as emissões gasosas produzidas. O método utilizado foi simulação a eventos discretos, cujo modelo computacional foi construído por meio do software livre e de código aberto denominado Ururau. Os resultados mostraram que a decisão quanto à escolha dos veículos em determinadas situações pode reduzir as emissões de gases geradas pela frota. Com isso, foi demonstrada a possibilidade de redução dessas emissões apenas pela introdução de modificações em procedimentos operacionais, sem necessidade de investimentos em novas tecnologias. Palavras-chave:Simulação. Gases do efeito estufa. Transporte. Emissões. Cana-de-açúcar. Abstract:The aim of this work was to analyze gas emissions from a truck exhaust system during the transportation of sugarcane from producing sources to a particular mill. Alternative scenarios for the freight handling were investigated considering a system performance variable, transportation time, and gas emissions produced. The method applied was the discrete event simulation, which computational model was built using a free and open source software called Ururau. Results showed that the decision concerning the choice of vehicles in specific situations can reduce gas emissions generated by the fleet. Hence, it was demonstrated the possibility to reduce these emissions just introducing changes in operational proceedings, without investing in new technologies.
