Estudo de caso: cronoanálise para identificação de gargalos no recebimento de uma fábrica de rações

Abstract

The present study aims to apply time study techniques to a bran dumper process and record times to identify possible bottlenecks in the receiving line of a feed factory. The chronanalysis was conducted considering normal time, cycle time, and standard time, as well as tolerance allowances and the mapping of the receiving line and the subprocesses within the bran dumper. Regarding the specific objectives, the study mapped the receiving line, identified queue points, and carried out the time study, in addition to identifying the limiting bottlenecks of the line. Time records were obtained using a spreadsheet with graphical resources to compare the average time of trucks in each process of the line, providing a basis for identifying bottlenecks. The time study tool proves to be a versatile method for analyzing times, activities, and movements, serving as a support for managerial and strategic decision-making. With this study, it can be understood that the bottleneck process in the truck receiving flow is the sampling and quality acceptance stage, in which the raw material is subjected to analyses for validation. This process can be optimized, as the bottleneck occurs due to the inefficiency in the relationship between the laboratory and the position of the sample collector.
