AKAY* Kahramanmarafl Sütçü ‹mam University, Faculty of Forestry, Department of Forest Engineering, 46100 Kahramanmarafl - TURKEY Received: Abstract: An unlimited number of alternative paths can be generated to connect 2 end points. Modern optimization techniques, which perform a systematic search for an optimum solution, can be used to solve such complex problems. In the field of highway design, various optimization techniques have been applied to locate a path between 2 known locations. However, there has been little optimization application in current forest road design systems. These systems are used as a tool to perform the mathematical calculations required to make basic manual road design. This study introduces a new method that integrates 2 optimization techniques for designing forest roads: linear programming for cut and fill balance and a “heuristic” approach (simulated annealing) for the selection of vertical alignment. This method provides the designer with a rapid evaluation of alternatives to design a path with minimum total costs, while conforming to design specifications, environmental requirements, and driver safety.

Karayolu planlanmas›nda, bilinen iki nokta aras›ndan bir yol geçirmek için de¤iflik optimizasyon teknikleri uygulanmaktad›r. Bununla birlikte, günümüz orman yolu planlama sistemlerinde optimizasyon uygulamalar› azd›r. Bu sistemler elle yap›lan temel yol dizayn›nda gerekli matematiksel hesaplamalar› yapmak için kullan›l›r. Bu çal›flma orman yollar›n›n planlanmas›nda iki optimizasyon sistemini .
