Abstract(s)
O presente projeto tem como objetivo analisar e propor uma solução para a mitigação de erros de quantidade em processos de picking no contexto de um operador logístico 3PL sediado em Portugal. A investigação decorreu num ambiente real de armazém, onde, apesar da utilização de um sistema de gestão de armazéns (WMS), foram registadas ocorrências recorrentes de divergências entre as quantidades expedidas e as quantidades efetivamente solicitadas. O estudo seguiu uma abordagem mista, combinando análise documental, observação direta e entrevistas a operadores. Foi identificado que a ausência de um controlo físico de verificação das quantidades no momento da separação contribui significativamente para a ocorrência de erros. A proposta de solução consiste na implementação de um sistema de verificação por peso, picking by weight, integrado no WMS, que permite confirmar automaticamente a quantidade separada antes da expedição, funcionando como um mecanismo Poka-Yoke digital. Os resultados esperados incluem a redução dos erros de picking, a melhoria do indicador On Time In Full (OTIF) e a diminuição de custos associados a retrabalho e não conformidades. O projeto contribui para o reforço da qualidade operacional e para o aumento da fiabilidade do processo de expedição em operadores logísticos 3PL.
This project aims to analyse and propose a solution to mitigate quantity errors in picking processes within a Portuguese third-party logistics (3PL) operator. The research was conducted in a real warehouse environment where, despite the use of a Warehouse Management System (WMS), recurring discrepancies were observed between shipped quantities and the quantities actually requested. The study followed a mixed-method approach, combining document analysis, direct observation, and interviews with warehouse operators. It was identified that the absence of a physical control mechanism to verify quantities at the moment of picking significantly contributes to the occurrence of errors. The proposed solution consists of implementing a weight verification system – picking by weight – integrated into the WMS, which automatically confirms the quantity picked before shipment, acting as a digital Poka-Yoke mechanism. The expected results include a reduction in picking errors, improvement of the On Time In Full (OTIF) indicator, and a decrease in costs associated with rework and nonconformities. The project contributes to strengthening operational quality and increasing the reliability of the shipping process in 3PL logistics operations.
