Study of a method-time measurement system in an electronics assembly line Pedro Tavares Pinhão Masters dissertation Supervisor at FEUP: Prof. Paulo Osswald Master in Industrial Engineering and Management 2015-07-01 Study of a method-time measurement system in an electronics assembly line “Never (…) was so much owed by so many to so few”- Winston Churchill y ii Study of a method-time measurement system in an electronics assembly line With the globalization of markets and an increasingly competitive environment of the industrial electronics sector, there is a need to the optimize processes, the development of new solutions and standards. Bosch, like the rest of the industrial sector, aims for continuous improvement, and the Bosch Ovar Plant has as a target, until the end of the year, the implementation of a predetermined method-time system. This system allows an accurate time prediction of the work cells processes, when planning production and the optimization of work cells following the principals of motion economy. Even though the link between the use of a method-time measurement system and company performance is hard to measure, the capacity to “predict” time of products can result in economical and time savings. During the project, various work cells in the Bosch Ovar plant were studied: its methods and processes (from regular assemblies to welding) and their corresponding time; and both test if the use of a method-time system was possible, and in that case, which of the systems would be more appropriate (MTM.1; MTM-UAS; MTM-MEK). It was possible to conclude that the use of MTM-UAS system was preferred over the use of MTM-1, based on the simplicity, accuracy of times in batch production and the processes present at Bosch Ovar Plant. However, in some work cells, the use of a MTM system was not possible, mainly due to processes complexity or mechanization of the movements within the work cells. iii
