Resumo: | Additive Manufacturing is a technology that has been in constant development and is being adopted for more and more companies. This new method can be a solution to various problems within the company, being one the spare parts management that due to the peculiarities of their demand function becomes a high cost activity. Therefore, the objective of this thesis is finding a possible solution for reducing that cost. In order to meet such objective, the costs related to the optimal inventory management policies that should be adopted were comparedto traditional technologies and with additive manufacturing. First, a preliminary literature review has been done, with the objective of identifying referenced cost models for performing the comparative analysis. Then, a mathematical model was formulated to compare the cost of a traditional inventory policy and a policy optimized for additive manufacturing technology. The model developed has been applied to a case study from Irritec where 3 different demands were chosen to analyze the difference between having a higher or lower number of parts per year in stock. The results obtained show that the manufacturing costs are high for these parts representing a high percentage in the final cost. Although, the cost of inventory holding cost can help deciding on using one method or the other due to the large divergence between the values of inventory and this cost will influence the way the supply chain works. It is also possible to see that at lower number of pieces is more convenient to use the new technology while with the increase of pieces the traditional becomes more economical. |

Este novo método pode ser uma solução para vários problemas dentro da empresa, sendo um deles a gestão de peças sobresselentes que devido às peculiaridades de sua função de procura se torna uma atividade de alto custo. Portanto, o objetivo desta tese é encontrar uma solução possível para reduzir esse custo. Para atingir esse objetivo, os custos relacionados com as políticas ótimas de gestão de inventário que deveriam ser adotadas foram comparados nas tecnologias tradicionais e de produção aditiva. Primeiramente, foi realizada uma revisão preliminar da literatura, com o objetivo de identificar modelos de custo referenciados para a realização da análise comparativa. Em seguida, um modelo matemático foi formulado para comparar o custo de uma política tradicional de inventário e uma política otimizada para a tecnologia de produção aditiva. O modelo desenvolvido foi aplicado a um estudo de caso da Irritec, onde três procuras diferentes foram escolhidas para analisar a diferença entre ter um maior ou menor número de peças em stock por ano. Os resultados obtidos mostram que os custos de produção são altos para essas peças, representando uma alta percentagem no custo final. No entanto, o custo de manutenção de inventário pode ajudar a decidir entre usar um método ou outro devido à grande divergência entre os valores do stock e porque este custo influenciará o funcionamento da cadeia de abastecimento. Também é possível ver que com um menor número de peças é mais conveniente utilizar a nova tecnologia, enquanto com o aumento de peças o processo tradicional torna-se mais económico.2022-07-28T00:00:00Z2019-07-29T00:00:00Z2019-07-292019-06info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10071/21765TID:202274713engSantos, Mariana Areosainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2023-11-09T18:02:04Zoai:repositorio.iscte-iul.pt:10071/21765Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T22:33:22.676680Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse |
