Otimização das linhas de produção de uma empresa vínica através de ferramentas lean

Abstract

This dissertation describes a project whose main objective was the optimization of thebottling lines of a wine company through the implementation and improvement of Lean tools andpractices. The use of performance indicators such as Overall Equipment Effectivness (OEE) andthe analysis of the company's production history assessed the success of the measures taken.At Aveleda S.A., the wide variety of products in existence brings with it daily challengesin the bottling section and in tasks parallel to the production lines, namely in the changes of partsin the equipment, in the management of human resources, in the arrangement of the plant layout,in the leftover of raw material and other waste that encourages undesirable stoppages by themanagement.In order to reduce the waste created during wine bottling, techniques such as the SingleMinute Exchange of Die, Visual Management, 5S and standardisation were applied.The Single Minute Exchange of Die method proved promising, however the process wasnot complete during the internship period and it was still necessary to train the operators involvedin the set ups of the bottling lines. Nevertheless, the implementation of 5S and VisualManagement contributed to the reduction of downtime on both bottling lines analysed.Moreover, the standardisation of processes, namely manual tasks (parallel to the bottlinglines), set ups, equipment adjustments and wine changes at the filler were also the subject ofintervention.The standardisation of these procedures focused on the elaboration of work standardsand the alignment of a matrix, in the case of wine changes, which allow the operator to follow thesame procedure during tasks, being as productive as possible, and know how much wine to rejectin a change between two articles with different wines, respectively. The analysis of this matrixsuggests that the "turning point" between the acceptability of wine conditions and its rejection issugar.In terms of evaluating the effectiveness of Lean intervention in bottling lines, the used keyperformance indicator (OEE) improved only in line 3, increasing nearly by 7% between the 3rdquarter of 2019 and the same period in 2020, but remained practically unchanged in the case ofbottling line 2. The difference may be seen in its explanation provided by the introduction of newproducts in bottling line 2, which increased the degree of difficulty for workers in dealing withbottling lines.In short, the documents produced as part of this dissertation help and simplify decisionmakingfor the production management team as they have improved the prediction of productivity,and consequent delivering of the products in the stipulated Lead Time.
