What we found is that we could retire basically 15 percent of the total length of the road network during the next couple of decades and still increase net present value by about one or two percent.

Business Challenge story

The College of the Environment at the University of Washington needed to manage its extensive forest road network with minimum environmental impact.


The College leverages IBM® ILOG® CPLEX® Optimizer to develop algorithms and solve complex problems related to optimizing the forest road network while supporting highly efficient timber harvests.


Drives greener, more cost-efficient management of forest resources; 2% potential increase in timber revenues through more efficient harvesting;15% of the forest roads could be retired, reducing impact on salmon and other wildlife
