Landing efficiency was assessed through simultaneous activity sampling of the loader, processor, and two rubber-tired skidders.
Skidding activity sampling results indicate that harvesting the additional small non-merchantable trees congested the landing.
Since processor productivity per tree or volume was not directly measured, the following formula, using activity sampling results, was used to estimate its productive capability:
WOP = average percent of activity sampling observations that a skidder was waiting on the processor
WOS = percent of activity sampling observations that the processor was waiting on a skidder
This formula reduces the processor's productivity by the total percentage of skidder and processor waiting time recorded during activity sampling.
After discussion, it was agreed that the survey would take the form of activity sampling to be carried out by supervisors.
