"A comprehensive study of a number of in-forest wood energy supply chains was undertaken to\ncollect empirical data on many aspects of both the stand and operational parameters therein. The\ndata was then used to develop statistical models, so that a number of harvesting systems could be\ncompared in a simulated environment. The simulated environment had two factors: the mean\ndiameter at breast height (dbh) of the stand (cm), and the mean extraction distance (m). The\nharvesting systems compared were: cut to length (CTL) harvesting, CTL harvesting with\nchipping of the pulp assortment, and whole tree harvesting with terrain chipping of the whole\ntrees. Not only were models developed on the productivity of the machines, but a taper equation,\ndbh to total height model, and a set of dbh distribution models were developed to predict the\nvolumes of the assortments attributable to each harvesting system down to the tree level. The\nproductivity models then used this data to estimate a cost of production per hectare for the\nharvesting systems. A value per unit volume of the assortments was taken from literature, and a\nprofit analysis performed for each harvesting system. The simulation results show that whole tree\nharvesting and terrain chipping returns the highest positive profit for all levels of mean dbh at\nshort extraction distances, but suffered from the machine interaction in the terrain chipping\nsystem at long extraction distances. The machine interaction between the terrain chipper and the\nchips forwarder was analysed using discrete event simulations. CTL harvesting and chipping of\nthe pulp assortment returned the highest positive profit at longer extraction distances."^^ . "2012-06" . . . . "Waterford Institute of Technology"^^ . . .
