The analysis and assessment of productivity in the processing of beech logs on the example of the selected production system in Serbia by applying statistical modeling
This paper presents the results of the study of the influence of the selected
factors on the productivity of the processing of beech logs on the example
of the selected producer of sawn timber in Serbia by applying statistical
modeling. The analysis covered three basic factors that have an impact on
productivity: the length, middle diameter and number of cuts on the logs of
beech that were processed during the observed period. The research was
carried out on a sample of 105 logs, and it contained various sizes of
middle diameters, lengths and number of cuts. The research aimed to review
the functional dependence of selected factors and productivity in order to
reach appropriate conclusions, provide expert recommendations and measures
to increase productivity and make appropriate forecasts of possible
productivity values. In order to examine the functional dependence of the
selected variables, statistical modeling was performed in SPSS, v.20 and MS
... Excel software packages, where the selected dependent variable is the number
of logs processed in one hour, and as an independent variable the volume was
taken into consideration (which contains the middle diameter and the length
of the logs) and the number of cuts. Statistically obtained parameters
showed a significant influence of the volume and number of cuts on the
change of the number of logs which are processed in one hour. In the
obtained regression model the correlation coefficient R is 0.994, while the
coefficient of determination R2 = 0.988. Since in sawmill processing
productivity is most often expressed as the volume of processed logs in the
unit of time, a transformed form of the equation shows the dependence of the
volume on the number of logs and the number of cuts. By setting the
hypothesis and by interpreting the statistical indicators, it has been found
that the impact of the analyzed factors is very high, but that, in addition
to them, productivity is influenced by technical and organizational factors.
