Optimization of Cable Logging Layout Using a Heuristic Algorithm for Network Programming
نویسنده
چکیده
This paper describes a methodology for optimizing cable logging layout using a heuristic network algorithm. The methodology formulates a cable logging layout as a network problem. Each grid cell containing timber volume to be harvested is identified as an individual entry node of the network. Mill locations or proposed timber exit locations are identified as destinations. Then, each origin will be connected to one of destinations through alternative links representing different cable roads, harvesting equipment, landing locations, and truck road segments. A computerized model incorporating the methodology is introduced. The model is intended to optimize landing, harvest equipment, logging profile, and road location simultaneously using information from GIS layers. A heuristic method for network programming is used as an optimization technique in the model.
