On the basis of an analysis of recording the activity of workers in felling and
primary conversion the following conclusions may be drawn:
1) When recording the work by the work sampling method the observer is
more engaged than when timing the respective work by the stop-watch time study
2) A stop-watch time study recording of measured data is more complex than
that in the work sampling method.
3) The structure of the work time established by the work sampling method
almost equiablled the structure established by the stop-watch time study method.
4) With work sampling in felling and primary conversion — when applying
variable observation intervals established according to the table of random numbers
— are not achieved results more accurate than the corresponding recording
at isochronous observation intervals.
5) The best results of recording by the investigated variants of the work
sampling method we obtained when isochronous obseration intervals of 30 seconds
6) The work place times according to the units of converted assortment —
established by work sampling method with isochronous observation intervals of
30 seconds — are sufficiently reliable.
7) Times participating with a small percentage in the work place time have
not been established statisticaly in a satisfactory manner when employing the
mentioned variants of the work sampling method. This may turn out to be an
important drawback when employing the work sampling method in the setting
up of work place times differentiated according to the operations.
