Melhorias no pcp de uma empresa de injeção plástica para reduzir os custos de desvios na programação das ordens de produção

Abstract

Production Planning and Control (PPC) plays a crucial role in the efficiency of production process management. This work describes a set of actions focused on PPC in a plastic injection industry, aiming to identify and reduce costs through the analysis of deviations in the production orders scheduled by the PPC. To achieve this objective, a diagnosis of the existing process was carried out, and root causes were identified through cause-and-effect analysis and the GUT matrix, which allowed for the development of an action plan to reduce costs associated with production orders. The action plan proposed improvements and actions with a constant focus on the continuous improvement of the process. As a result, various areas saw improvements, leading to a 13.5% reduction in deviations in production orders, which represents a financial gain of R$ 96,810.78. Consequently, this resulted in a more effective production scheduling with fewer deviations and a production process with lower work-in-progress inventory, reflecting a more efficient use of resources in the planning and scheduling of the PPC. Additionally, production orders showed a 14.5% increase in adherence between planning and execution, resulting in reduced costs a
