Utilização da simulação em avaliação de proposta de aplicação do pensamento enxuto em ambiente administrativo de uma instituição federal de ensino superior

Abstract

Lean Manufacturing focuses on eliminating waste by improving its processes, however, waste is not just concentrated production processes, but also on administrative activities. The adaptation and application of lean concepts in administrative environments is called Lean Office and favors companies to become more organized and competitive. However, it still presents complexities to predict the results of changes. In this sense, the simulation can be used to facilitate the analysis of impacts in advance, allowing the visualization of changes in processes without changing reality. In this context, this work proposes the use of simulation in an integrated way with lean concepts, through the Value Stream Mapping, to evaluate in advance the results expected by the proposal of implementing lean concepts in administrative environments, analyzing the impact of document replacement by fingerprints on an object of study. This, is characterized as an administrative environment of a Federal Institution of Higher Education (IFES), which performs financial and accounting activities and was chosen for presenting difficulties in meeting its demand. In order to identify in the works already published, with regard to the adaptation and application of lean concepts in administrative environments, results achieved, difficulties identified and solutions implemented, as well as whether the Discrete Events Simulation has been used to reduce resistance of people to the implementation of lean concepts in these environments a Systematic Literature Review was conducted. The results achieved showed not only a reduction in the average lead time from the current state to the simulated future state, but also a significant gain in capacity. The average lead time in the current state, which was above 270.000 seconds, or 75 effective hours of work, was reduced in the future state to somewhere around 180.000 seconds, or 50 effective hours of work. That is, a reduction of 33.33%. The amount of notes paid, which was a maximum of 145 per month, according to actual data from the current state, was increased in the future state to above 320. That is, an increase above 120%.
