CLASSICAL AND ORDER STATISTICS OF EFFECTIVE ACTIVE TIME OF FELLING AT USE CHAINSAW

Keywords: felling, effective active time, early thinning, pine stands
Abstract:

 

The time, within which accordingly to its application machine works, and an object of work and working groups are under load,is the effective active time. The purpose of the research was the classical and order statistics of effective active time of felling at use chainsaw. The average effective active time of felling of one tree was about 2 s. The cut trees were strong statistical diversified from the point of view of effective active time of felling. The positive skewness coefficient has confirmed, that statistical units with value of feature below arithmetic mean were prevailed – right-sided asymmetry.
