MTM-UAS is known as a 3rd level MTM system and was developed between 1976 and 1978 by a consortium of the German, Swiss and Austrian MTM Associations. The system was specifically developed for small batch production where speed of analysis has priority over methods and operational detail.
The data was developed having in mind the following objectives -
The system requires the following production characteristics -
The data was derived from MTM-1 analyses from films of typical batch production operations -
UAS level 1 (Basic Operations)
Consists of seven activities
The data Card shows a total of 77 unique codes, whose values range from 5 to 160 TMU (0.15 to 4.8 secs).
The accuracy of MTM-UAS, compared to MTM-1, has never been officially defined but generally it is claimed not to be suitable for non-repetitive cycles of less than 1.0 minute (2,000 TMU) but again as with MTM-2 it has been used successfully for shorter non-repetitive cycles.
