Timber Transport – Reduction of Empty Runs by Back Haulage and Triangle Routes

Thomas Smaltschinski* and Martin Müller

Back haulage or triangle routes are a suitable means of achieving a reduction in empty runs in timber transport. The calculation is done using linear programs. One problem with linear programs is the high complexity caused by the combinatorics involved in generating the routes. This can be reduced if the characteristics of back haulage or triangle routes are taken into account. The complexity then drops drastically and well-compatible linear programs are obtained. The methodology presented in this study was tested for the harvest sizes of the 2015 fiscal year of the Bavarian State Forest Enterprise. Pure back haulage routes lead to a reduction in empty runs of 17.2% and the combination of back haulage and triangle routes lead to a reduction of 20.2%.
