Forest road network design based on economic and environmental criteria with weighting the indices using PEGGER software

 Roads in the forest have several tasks and costly road construction has led the designers to design the best network.

  For this purpose, data layers (slope, direction, forest type, etc.) were prepared and multi-criteria evaluation method of these characteristics was used for preparing suitable plan such that after the classification and valuation of inner layers of maps, Pairwise comparison method in Analytic Hierarchy Process (AHP) was used for weighting the characteristics and a compilation of experts opinions which was designed into questionnaires, entered in the process and using Expert Choice software, the importance coefficient of each layer was obtained.

 Weights of factors, characteristics, and restrictions was imported on multi-criteria evaluation model and the combination of characteristics and overlapping the layers according to their importance factor was performed based on multi-criteria evaluation model.

Option 6 were individuated as the most desirable option because of the minimum amount of multiplying the road length in total distance of skidding and the insignificant difference in soil operation volume.
