Estudo de cronoanálise em uma indústria alimentícia

Abstract

This Undergraduate Thesis aimed to propose operational improvements through the application of time and motion study in a food industry located in the state of Paraná, Brazil. To achieve this goal, nine manual operations from the hamburger production line were timed and analyzed. The activities were evaluated based on normal time, allowance assignment, and standard time calculation, using time study methodology. As specific objectives, the study mapped and described the production process, applied timing techniques, analyzed the collected data, and proposed operational improvements. The effectiveness of the time and motion study was demonstrated by the quantitative results obtained, such as an average reduction of 18.6% in the total time of the observed manual operations, representing a direct productivity gain. Additionally, the tool enabled the identification of a specific bottleneck - operation 8 - allowing for practical improvements such as task reordering and the elimination of unnecessary movements. The development of an automated time study spreadsheet reinforced the applicability of the results by providing a resource that systematizes standard time calculations and can be used by the company’s own team for future analyses. Therefore, it was confirmed that time and motion study not only fulfill its technical role in time measurement but also serve as a strategic decision-support tool by promoting standardization, waste reduction, and sustainable improvements in production processes.
