Abbreviated WORK-FACTOR, AWF, has as its time unit the Abbreviated Unit, AU, measured in 0,001 minute, so 1000 AU = 1 minute, while the Abbreviated Elements will be rounded to a multiple of 5 AU. Finished and published in 1951.
AWF has 8 elements and the AWF time table has in total 32 time classes.
The AWF system is a method study and time study system which is
• Suitable for short cycle work if the total series of products is not too large,
• Suitable for large cycle work if the total series of products is rather large,
• Great use in transportation, warehousing and distribution, repair & maintenance shops, a.t.l.
• Provides less information for method study than RWF or VWF,
• Provides yet more information for method study than the stop watch method,
- a deviation w.r.t. DWF of 10 à 12% is accountable as total costs are concerned,
- the system has very few rules,
- the system is easy to understand,
- the analysis is very fast. It is very suitable to generate key figures.
Application of AWF may be justified where the part of work to be analyzed is just a small part of the total work to be analyzed and of the costs of operation. So, where the deviation has only a minor influence on the total costs.
The intrinsic AWF tempo corresponds with tempo 72 Bedaux or 90 BSI or 120% (ASME).
At the moment AWF is replaced by VWF.
