Regras de sequenciamento e tamanho de lote da produção: estudo de simulação em uma job shop

Abstract

One of the most important points when we think about the production of goods is the organization of the processing activities, which directly influence the sequencing of production, setup times and size of processing batches. This article aims to evaluate the impact of these factors on the makespan. In order to do this, experiments were carried out in a computational environment inside the FlexSim software in a job-shop organized by processes. The results indicate that the size of the transfer batch, when it has a low setup time, is more important than the production sequencing rule to which the system will be submitted. By doing so, it is possible to conclude that – for sectors that have a low setup time – it is more advantageous to fraction ate the batches into smaller batches, in order to reduce the total transit time of the items.
