Resumo: | The complexity of the organizational processes and the needs of improving their results make the industrial companies to search for effective alternatives for the planning and management of production systems, which generally impact in the performance of the entire supply chain. In this context, the use of optimization models and tools can give the organization great benefits. The present study proposes a linear programming model for the optimization of the aggregate planning for the manufacturing of items of a metalworking sector company (drill bits company). The objective function of the proposed model maximizes the contribution margins of the products, respecting the capacity and demand constraints for multiperiod planning. This study also presents evaluation scenarios that may be useful in the management of the manufacturing activities. The applied methodology shown itself to be powerful to define and improve the aggregate planning activities, helping to determine the products mix and upgrading the management decisions, which confirms the viability of the applied method and reaches the goals. Assuming a specific scenario representing the current conditions of the production plan conducted in the company, the proposed model achieved an improvement in the contribution margin of more than 7%. In addition to assisting in decision making, the use of the mathematical model allows the generation of an important database for managers, who can report to the executives the characteristics of the production planning and company's results, in a quick, direct and quantitative way. |

Nesse contexto, a utilização de modelos e ferramentas de otimização pode trazer grandes benefícios para a indústria. Esse trabalho apresenta um modelo de programação linear para a otimização do planejamento agregado da fabricação de itens de uma indústria do setor metalmecânico (conjunto de famílias de brocas). A função objetivo do modelo proposto maximiza as margens de contribuição dos produtos, respeitando as restrições de capacidade produtiva e atendimento à demanda para um planejamento multiperíodos. Por meio do modelo matemático, são avaliados diferentes cenários que podem ser úteis no gerenciamento das atividades de planejamento da produção. A metodologia aplicada mostrou-se útil para a otimização do planejamento agregado da produção, auxiliando na definição do mix de produtos a serem fabricados, bem como os resultados para diferentes cenários, subsidiando a tomada de decisões gerenciais. Para o cenário que considera as condições do plano de produção realizado atualmente pela empresa, o modelo proposto apresentou uma melhoria na margem de contribuição de mais de 7%. Além de auxiliar na tomada de decisões, o emprego do modelo matemático proporciona a geração de uma base de dados importante para os gerentes, que poderão reportar aos executivos as características do planejamento de produção e resultados da companhia, de forma rápida, direta e quantitativa.Associação Brasileira de Engenharia de Produção2019-03-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfvideo/mp4https://www.producaoonline.org.br/rpo/article/view/301310.14488/1676-1901.v19i1.3013Revista Produção Online; Vol. 19 No. 1 (2019); 21-43Revista Produção Online; v. 19 n. 1 (2019); 21-431676-1901reponame:Revista Produção Onlineinstname:Associação Brasileira de Engenharia de Produção (ABEPRO)instacron:ABEPROporhttps://www.producaoonline.org.br/rpo/article/view/3013/1750https://www.producaoonline.org.br/rpo/article/view/3013/1751Copyright (c) 2019 Revista Produção Onlineinfo:eu-repo/semantics/openAccessGassen, GustavoGraciolli, Odacir DeonisioChiwiacowsky, Leonardo DagninoMesquita, Alexandre2019-03-15T10:37:00Zoai:ojs.emnuvens.com.br:article/3013Revistahttp://producaoonline.org.br/rpoPUBhttps://www.producaoonline.org.br/rpo/oai||producaoonline@gmail.com1676-19011676-1901opendoar:2019-03-15T10:37Revista Produção Online - Associação Brasileira de Engenharia de Produção (ABEPRO)false |
