Aplicabilidade de métodos de estudo de tempos e movimentos na intralogística: evidências em ambiente automotivo

Abstract

The increasing complexity of production and logistics systems has intensified the need for reliable methods to analyze and plan operational work. In the automotive industry, although Predetermined Motion Time Systems (PMTS), particularly the Methods-Time Measurement (MTM) system, are widely employed for production planning and workforce sizing, their application to intralogistics operations remains scarcely explored in the literature. In this context, this dissertation investigates the applicability of the MTM and time study methods in the intralogistics operations of an automotive manufacturing company. The objective of this study is to compare these methodologies in the planning of intralogistics operations while also considering the influence of the learning curve on operational performance. The research is characterized as applied, adopting a qualitative approach and conducted through a single case study whose development incorporated the principles of action research by involving the diagnosis of an organizational problem, the researcher’s active participation in data collection and analysis, the validation of the results with the company, and the proposal of recommendations for process improvement. The investigation was based on documentary analysis of MTM-planned times, direct observation of logistics operations, time measurements obtained through time study, and a comparative analysis of the results under actual operating conditions. The findings revealed differences between planned and observed times, influenced by the variability of intralogistics activities, operational travel, the learning curve, and ergonomic factors. It is concluded that the complementary use of MTM and time study provides a more comprehensive assessment of intralogistics operations, contributing to workforce sizing, operational planning, and the continuous improvement of logistics processes in industrial environments.
