Log Bucking Simulation

Bucking Simulation

  • Bucking and any subsequent sorting may occur at the stump or landing or at the mill, and affects everything that comes afterwards. In the US Pacific Northwest it significantly affects the Scribner scale and therefore how much is paid for the logs.
  • So HALCO has invested in a significant development effort to making realistic simulations of rule-based and optimum bucking of both stems and logs, with a view to predicting the outcomes and optimizing the rules. We refer to stems being bucked to logs, and logs being bucked to blocks, although in cut-to-length operations, this may take place in one step.
  • The WOODSIM™ program is HALCO's principal vehicle for simulating and optimizing bucking and sorting of stems or logs to sawlogs, peelers and pulplogs. It can predict the outcomes from pre-specified bucking and sorting procedures or rules, or it can set up a database containing the outcomes from alternative procedures. This database becomes the input to our WOODMAN™ program which can choose between the alternatives.
  • The CTL-SIM program is a simplified and easy-to-use version of WOODSIM™ that simulates cut-to-length operations, with emphasis on emulating the procedures programmed into cut-to-length harvesting machines. Clients have achieved substantial benefits from using it to get control of widely scattered cut-to-length harvesting operations and controlling logyard inventory as a result.
  • The SAWSIM® program also contains optimum and rule-based bucking procedures which simulate both log bucking, and the sawing or peeling of the resulting blocks. It has been used many times to establish the potential benefits or otherwise from optimum bucking systems.
