Abstract(s)
Atualmente, devido maioritariamente ao avanço dos diversos sistemas tecnológicos e à maior facilidade em adquirir bens, a sociedade tornou-se mais exigente. Devido a este fator, a necessidade das empresas seguirem a mesma trajetória dos consumidores, para que a harmonia entre ambos esteja nivelada, levou a uma mudança na execução de processos e operações. A gestão de cadeias logísticas não foi exceção e surgiu a necessidade da criação de sistemas mais eficientes, tal como os sistemas de crossdocking, os quais promovem a movimentação rápida de produtos em que o armazenamento temporário dos mesmos deve ser o mínimo possível. Assim, o principal objetivo passa pela modelação e simulação de um sistema crossdocking com um armazém automático integrado, eficiente, oferecendo mais uma solução na área da logística de movimentação de produtos. No âmbito da presente Tese/Dissertação, apresenta-se o desenvolvimento de todo o trabalho, desde o estudo teórico dos conceitos até às conclusões finais sobre os resultados obtidos. O trabalho passou também por outras fases, devidamente identificadas e de conteúdo relevante. Através de layouts definidos, e após uma implementação do modelo no software utilizado, a obtenção de resultados, tendo em conta algumas variações a nível de componentes, teve sempre o foco dirigido nos sistemas deste tipo que se encontram em funcionamento em contexto real. Uma aproximação a este tipo de sistemas torna a simulação, embora virtual, bastante mais credível. Várias análises foram executadas para que os resultados gerados sejam abrangentes e completos.
Currently, mostly due to the advance of the technological systems, digitalization and the greater ease in acquiring goods, the society has become more demanding. Due to this factor, companies need to start to follow the same line of thinking as consumers, so that harmony between both are stabilized. This can lead to a change in the way how processes and operations are executed. The supply chain management was not an exception and it was necessary to create more efficient systems, such as crossdocking systems, which promote the fast movement of products in a distribution center. In these systems, the products can be stored with the conditon that the storage time is minimum and can not exceed a certain period of time. Thus, the main goal is to model and simulate a crossdocking system with an integrated and efficient automatic warehouse. With this model, another solution can be designed and it is meant to help with eventual logistic problems of this type. This thesis presents the development of the entire work executed, starting in the theoretical study of the concepts, ending with the final conclusions based on the results obtained. The work also went through other phases, all of them identified and with relevant content. Through defined layouts, and after an implementation of the model in the software used, the results were generated taking into account some variations at the level of simulation components, always focused on the existing systems in real context. An approach of this type of systems makes the simulation, although virtual, much more credible and reliable. Several analyzes were performed so that the results generated are comprehensive and complete.
