A Simulated Annealing Approach to Problems of the Transportation of Wood Raw Material
The planning process for producing wood raw materials includes forestry work such as transporation. This process is highly complex, both in implementation and design. In these studies, the transporting of wood raw material on the forest road network constitutes a significant portion of total production costs. Therefore, development of the most appropriate transportion plan is of great importance, not only technically, but also financially. In this study on the forest road network, a model of transporting wood raw material was developed. The algorithm of Simulated Annealing (SA) among the meta-heuristic techniques has been used for the analysis of the model. In order to introduce the model more explicitly, an experimental design and analysis has been applied in this study. During the process of experimental design, the multivariate analysis of variance was used in order to determine whether the applied factors are effective on the performance of the SA algorithm. Moreover, whether there is any difference between the levels for these factors was assessed by the Duncan multiple range test. It was concluded that using the transporting model in the research field can provide 14.45% savings in annual transportation costs. ‘Transport planning studies’ have provided significant savings in the workforce, time and cost with the use of SA and statistical methods.
