FPInnovations has developed a simulation based decision support tool to help log and sort yard managers quickly evaluate and quantify the impact of changes in the yard operation in a virtual framework. Some examples of changes that could be evaluated by the model include changes in the infrastructure, yard layout, machine combination, and yard throughput. The tool was tested and validated in a coastal log and sort yard, and is customizable to log and sort yards with similar operation. In this report, the model, its capabilities, and results from the test site are presented.
