Utilização da simulação a eventos discretos no planejamento e avaliação dos resultados esperados pela proposta de aplicação do pensamento enxuto no setor de registro escolar em um Instituto Federal de Ensino Superior

Abstract

Lean Manufacturing, an approach that emerged in Japan as a Toyota Production System, seeks to increase productivity and quality, while reducing waste, and is being increasingly applied in administrative environments. However, this application still faces difficulties, either due to its limited knowledge, or due to the difficulty in visualizing the expected results. In order to minimize these difficulties and increase the chances of success in the implementation, an increasingly used technique is computer simulation, since the expected results for the real system can be previously visualized in the virtual system. In this context, the general objective of this work is to employ the Modeling and Simulation method, through the Discrete Events Simulation (DES) in the evaluation of the results expected by the proposal of implementing lean thinking in the administrative environments of a Federal Institution of Higher Education (FIHE), more precisely, in the Management of School Records of Technical Courses and High School of IFMG, Campus Bambuí. The specific objective is to develop a Systematic Literature Review (SLR) to understand how lean thinking has been applied in administrative environments, particularly in those audiences, highlighting the contributions and difficulties pointed out by the existing literature, as well as the way in which the Simulation Discrete Events comes and can be used to leverage contributions and minimize the difficulties of implementing these concepts in these environments. The Value Stream Mapping was integrated with the Simulation steps, where the current and future value stream maps of the selected service families were modeled and simulated, obtaining as a result, through the elimination of waste, a reduction in Leads Times from the families mapped 93.5%, 47.4% and 59.6%, comparing simulated current and future states, and 92.8%, 45.0% and 61.0%, comparing current and future states drawn. First, such sets of values prove the significant reductions. Second, they also prove the coherence between the drawn maps, which are static and deterministic, and the simulated ones, which are dynamic and stochastic. With the general objective restricted to the use of Discrete Events Simulation to evaluate in advance the results expected by the proposed implementation of lean thinking to the object of study, the effective application of these concepts and their tools remains a natural proposal for future work.
