Abstract

ABSTRACT Currently, log transportation from the coniferous forests of Pakistan is done mainly by 4 x 4 flat-bed trucks (popularly known as Guttoos), mainly on low quality dirt roads (generally known as Guttoo roads) involving rehandling of logs at a transfer yard (transit depot). An improved timber transportation method using permanent forest rods and 2 x 4 turbo-charged (common wooden-bodied) straight trucks with trailer is proposed. The best combination of temporary and permanent roads is suggested as a fixed and variable cost network problem.
