Mapeamento de fluxo de valor aplicado a uma linha de produção da indústria cervejeira

Abstract

The management of raw-material warehouses remains highly challenging, requiring effective control to prevent shortages or excess inventory that may lead to production line interruptions or high storage occupancy, thereby generating additional costs. The study was conducted in a brewery located in Ponta Grossa, Paraná, which experiences stock shortages and desynchronization in activities such as withdrawal, transportation, and receipt of materials in the warehouse. Therefore, Lean Manufacturing tools such as Value Stream Mapping (VSM) and Kanban were applied to improve organization, planning, and operational performance. Data were collected to develop a current-state value stream map, through which improvement opportunities were identified in the bottle receiving stages by implementing Kanban in a way that the scheduling and unloading of materials occur according to the needs of the filling lines. Consequently, a future-state value stream map was developed. Thus, the objective of this study was to analyze the company’s operational context and to apply and propose the use of Value Stream Mapping (VSM) and Kanban to identify waste and suggest improvements for the brewery’s warehouse resulting in a reduction of 36 hours in the total lead time of the bottle supply process.
