Abstract
The paper presents the results on the systemic and statistic modelling of the process of pelleting fir tree sawdust powder. A systemic model is presented, specifying the inputs, commands and outputs. Based on experimental result, it is then attempted to perform a statistical modelling only using the technique of linear and nonlinear regressions. Results for the performances of qualitative modelling and estimations of system (pelleting process) behaviour are displayed, as well as some limitations on using statistic modelling based on regression technique. Although some results can appear as interesting, it is shown that any interesting point in the space of input and command parameters (point that is convenient or even optimal in exploitation) should be experimentally checked in the sense of verifying the properties highlighted by the functions found. This means that any theoretically convenient parametric combination should be experimentally validated through high resolution experiments.
