Improvement of logistic system for optimal roads’ construction and forest roads’ network planning

Results of the improvement of the logistic system for optimal roads’ construction and forest roads’ network planning are described in the article. A new version of the previously developed system is created. The system is characterized by a greater degree of spatial accuracy with subsequent possibility for change. The new version takes into account a relief of the environment. This consideration is essencial when designing effective network of forest roads. The methods and models, as well as the results of testing of the new system are described. Experimental results confirmed usefulness of the modified system, which takes into account the most significant factors affecting the complex. The model is also instrumental in choosing the right solutions. In these specific circumstances, the use of the modified system significantly increases efficiency of the wood harvesting industry as a whole, despite a slight increase in the cost of road construction.
