Comparison of Time Standardization Methods on the Basis of Real Experiment

The paper focuses on mutual comparison of currently most common methods for time standardization. For comparison of selected methods an experimental research in conditions of automotive assembly production was performed. Compared methods were direct measurement according to REFA methodology and two predetermined time systems MTM-1 and BasicMOST. Mutual comparison of results obtained by means of those 3 methods was performed. The experiment was performed on 21 assembly workplaces where time span of analyzed operations oscillated between 4 to 29 seconds. The main goal of the research was to demonstrate reliability, mutual accuracy and deviations of selected methods. A hypothesis needed for verification was stated, that individual methods should have maximal accuracy deviation ± 10%. Findings about time demands for performing the analysis according to selected method was a partial goal of our research.
