This master’s thesis focuses on the analytical evaluation and standardization of assembly operation times using predetermined motion time systems. In industrial practice, the most commonly applied methods are WorkFactor and MTM (Methods-Time Measurement). The research is conducted within the Industrial Engineering Department, which is responsible for the design and conceptual development of an assembly line. The study begins with the calculation of the customer takt time, followed by the determination of the work cycle time and the assembly line configuration. The main emphasis is placed on defining assembly times using the MTM-1 method, which replaces the previously applied WorkFactor system. A theoretical overview of both methods is presented, along with an analysis of the most influential factors and the most frequently used motion elements according to MTM-1. The primary objective is to evaluate and compare time values for common motion types—such as reaching, grasping, moving, positioning, assembling, and releasing—using both methods. The comparison is supported by a case study analyzing the assembly process of a rod mixer drive unit. The results reveal significant differences in assembly times between MTM-1 and WorkFactor and identify areas with the greatest potential time deviations when applying one method or the other.
