[pt] O tema armazenagem tem se tornado cada vez mais relevante na logística, tanto na academia, quanto nas empresas que dependem de centros de distribuição (CD). Esta dissertação tem como objetivo analisar a operação de um CD de uma empresa de cosméticos com base em seus processos e em seus perfis de atividades e, ainda, propor melhorias na operação visando ganhos de produtividade e acuracidade. No caso estudado, o comitê gerencial da empresa identificou a necessidade de promover ganhos de produtividade e acuracidade da operação bem como levantar oportunidades de melhorias, o que motivaram esta pesquisa. Para atingir esses objetivos, o estudo do caso foi estruturado em 3 fases: contextualização; diagnóstico e; elaboração de propostas de melhorias, plano de ação e implementação. O método de pesquisa utilizado na fase 1 consistiu em contínuas visitas in loco, pesquisa bibliográfica de artigos e livros nacionais e internacionais, na coleta e análise de dados extraídos dos sistemas de informação da empresa, realização de entrevistas semiestruturadas bem como entrevistas de validação, para então elaboração de diagnósticos e análises na fase 2. Como resultado dos diagnósticos da estrutura e processos do CD da empresa Alfa, são apresentados na fase 3 propostas de melhorias, planos de ação e oportunidades de ganhos logísticos para implementação. Nesta fase 3, as maiores oportunidades de ganhos foram identificadas nos processos de estoque e picking (preparação) sendo este último fundamentado no estudo dos perfis de atividades de armazenagem. Dentre as propostas implementadas, destaca-se a reestruturação da atividade de picking que atingiu bons resultados com uma correta reorganização e redimensionamento das posições de bases dos SKUs sem necessidade de adoção de nenhuma nova tecnologia. / [en] The theme storage has become increasingly important in logistics, both in academia, as in companies that rely on distribution centers (DC). This thesis aims to analyze the operation of a CD of a cosmetics company based on its processes and activities in their profiles, and also propose improvements in the operation aimed at boosting productivity and accuracy. In the case studied, the management committee of the company identified the need to promote productivity gains and accuracy of the transaction and raise opportunities for improvement, which motivated this research. To achieve these objectives, the case study was structured in three phases: context, diagnosis and, development of proposals for improvements, plan of action and implementation. The research method used in Phase 1 consisted of continuous on-site visits, literature search of articles and books, national and international, in the collection and analysis of data extracted from the company s information systems, semi structured interviews and validation interviews to then development of diagnostics and analysis in phase 2. As a result of the diagnosis of the structure and processes of the company Alfa CD, are shown in phase 3 improvement proposals, action plans and opportunities for implementation of logistics gains. In phase 3, the biggest profit opportunities were identified in the process of stock picking and (preparation) the latter being based on the study of profiles storage activities. Among the proposals implemented, there is the restructuring of picking activities that achieved good results with a proper reorganization and downsizing of positions of bases of SKUs without the adoption of any new technology.

MaxiDoor AB konstruerar och tillverkar ståldörrar och stålpartier efter specifika kundorder och är specialist på lösningar där hög säkerhet efterfrågas. Företaget ämnar expandera under kommande år och har sjösatt en investeringsplan för att göra verksamheten anpassad för en högre omsättning.  Detta arbete avser att se över och förbättra dagens materialförsörjning vad gäller stålprofiler med förutsättningar om förväntad omsättning för produktionsenheten ES kommer att öka från 100 mkr till 145 mkr samt att företaget vill bibehålla en enstycksproduktion. Detta ska lösas med hjälp av bland annat en lagerhiss. Parallellt med att tillverkningstakten förväntas öka måste även materialförsörjningen utvecklas för att klara framtida efterfrågan.  Med grund i teori och analys av nuläget konstateras att lagerutformningen snabbt blir komplex med de förutsättningar som existerar. Studiens slutgiltiga rekommendation är att dela upp lagret i tre sektioner; lagerhiss, grovbuffert och finbuffert. Detta får till följd en användarvänlig materialförsörjning som förväntas vara hållbar på sikt.  Lagerhissen avses förvara både ordrar med planerad och dedikerad förbrukning samt övriga profiler och slattar. På så sätt agerar hissen såväl lager som buffert. Grovbuffert och finbuffert brukas enligt en trattprincip där ordrar bryts ned till enstaka profiler som skall kapas. Avslutningsvis diskuteras olika aspekter kring materialförsörjningen och framtida arbete. / MaxiDoor AB designs and manufacture steel doors and steel segments to specific customer order and are specialist on solutions where high security is requested. The company seeks to expand during the coming years and have launched an investment plan to adapt the production for higher turnover.  This work intends to look over and improve todays material supply in terms of steel profiles with the basis that expected turnover for the production unit ES will grow from 100 mkr to 145 mkr and in addition the company wishes to keep a one-piece production. This will be solved with the help of, among other things, a vertical storage lift. In parallel with the expected increase in rate of production, the supply of materials must also be developed to meet future demand. Based on theory and analysis of the current situation, it is found that the storage design quickly becomes complex with the existing conditions. The final recommendation of the study is to divide the storage into three sections; a vertical storage lift, a coarse buffer and a fine buffer. This results in a user-friendly material supply that is expected to be sustainable in the long term. The vertical storage lift is intended to store orders with planned and dedicated consumption as well as other profiles and residual profiles. In this way, the elevator acts as both storage and buffer. The coarse buffer and fine buffer are used according to a funnel principle where orders are broken down into individual profiles to be cut. Finally, various aspects are discussed regarding the supply of materials and future work.
