The Methods-Time Measurement (MTM) tool has been gaining ground for offering costeffective solutions for products/services, focusing on time reduction and wastage elimination. Aiming at the optimization of operations, this research aimed to evaluate the operational results from the MTM tool in a medium-sized beauty salon in the Tianguá-CE city. To carry out the study, the services provided by the salon were evaluated to verify the one that was most relevant, highlighting the services of manicure and pedicure. In these services, a diagnosis of the current scenario was carried out, and MTM were applied to identify opportunities for their optimization. After obtaining the results and analyzing them, it was possible to reduce unnecessary activities by 54.61% in the pedicure service and 62.57% in the manicure service, resulting in more agile, efficient, and low-cost services. In addition to reducing unnecessary activities, this improvement was possible through the standardization of the other activities that make up the service and the reorganization of the layout. Therefore, it is concluded that the application of the MTM provided gains in productivity and in the quality of the service provided, as there was a reduction in waste and greater agility in the service.

“…The division of activities into movements, performed via the MTM, should be applied after the analysis of the entire structure of activities, including the logical organization of cognitive and motor actions (Bedny, Karwowski, & Voskoboynikov, 2015). Therefore, during Stage I, the best sequence of task execution was analyzed and defined before the application of the MTM took place.…”

Objective: The aim of this article is to analyze the influence of the variability of the standard time in the simulation of the assembly operations of manufacturing systems. Background: Discrete event simulation (DES) has been used to provide efficient analysis during the design of a process or scenario. However, the modeling activities of new configurations face the problem of data availability and reliability when it comes to seeking standard times that are effective in representing the actual process under analysis, especially when the process cannot be monitored. Method: The methods-time measurement (MTM) is used as a source of standard times for simulation. Assembly activities were performed at a Learning Factory facility, which provided the necessary structure for simulating real production processes. Simulation performances using different variability of standard times were analyzed to define the impact of data characteristics. Results: The MTM standard time presented an error of approximately 5%. The definition of the data variability of standard times and the statistical distribution impacts were shown in the simulation results, with errors above 6% being observed, interfering with the model reliability. Conclusion: Based on the study, to increase the adherence of a simulation to represent a real process, it is recommended to use triangular distributions with central values greater than those established via the MTM for the representation of the standard times of new assembly processes or scenarios using DES. Application: The study contributions can be applied in assembly line design, providing a reliable model representing real processes and scenarios.

“…The results obtained are compared using analysis of variance, and it is shown that the values obtained by MODAPTS are acceptable when compared to these other methodologies. Bedny et al (2014) applied timing systems with pre-determined times and movements in the temporal analysis of a worker's activities. Two series of experiments were carried out with students at the University of Odessa, all of them being right-handed and using their dominant hand to perform the experiment and the times of these students were analyzed via MTM-1 (a variant of MTM).…”

Purpose The purpose of this paper is to present a precise comparison between a pre-determined time rules and the evaluation performed with the help of a manual chronometer using data from a line assembly in an automotive industry besieged in the state of Paraná, Brazil. Nowadays, it is possible to verify several tools of measurement of task times, some taking less time and causing less wear of the evaluator than others, but not being in accordance with the real conditions of the workers of a certain industry. Design/methodology/approach The developed paper has its methodology based on two methods of time analysis, one of them being an adaptation of the MODular Arrangement of Predeterminated Time Standard (MODAPTS) method – called MODAPTS 2. This method is used by the industry in analyzed in this work and the other through the use of simple manual timing, through the digital timer, of the stages developed in a workstation. Findings The study shows that for each operation analyzed, thus presenting a situation of minimum waste, it becomes possible to judge which reasons exist for the operator during manual timekeeping not to reach the optimum times generated by the system of pre-determined times and movements (PMTSs) questioned. Research limitations/implications This study is conducted on an automotive enterprise in a period of confidentiality, which means that only a single workstation is able to be studied. This means that the comparison obtained between the time measurements methods used, and the evaluation of the MODAPTS is carried out with the best possible movements and gestures, disregarding then that the wastes can still be postulated to the whole assembly line. Originality/value With the automation in industry, where assemble tasks are usually developed manually, it is believed possible to discard the option of measuring task times in its classic and manual form, using a timer, yet during this process, there will be variables that may not be considered by pre-determined measurements methodologies. The work developed by this paper presents different variables that are not examined by the methods of PMTS, not frequently seen in the literature, as well as the difference that occurs between the measurement of times with stopwatch and the use of PMTS, which, in its original form, disregards the wastes that the operator has in their movements.
