Log-Making Simulation
HALCO developed the LOGSIM™ program to simulate log-making in New Zealand, where logs were manufactured for sale, to various grade specifications.
Typical applications of LOGSIM™ include:
- Evaluation of manual cutting decisions.
With LOGSIM™, the difference in value between manual cutting decisions and the optimum (highest-value) solution can be determined. Through this analysis, quality control of manual log making crews can be improved, and the gap in value between manual and optimum cutting may be closed. - Evaluation of the effects of different log-grade specifications or cutting plans.
With LOGSIM™, the effect of adding a new log grade, or changing the grade specifications of an existing grade, may be determined. For example, one may determine the effect of adding a new length to the cutting plan for a certain grade on the total volume of that grade produced. In addition, the effect of this change on the total value recovered from a timber supply may be determined. - Training of manual log-making personnel.
LOGSIM™ may be used interactively, to recalculate instantly the value of alternative cutting solutions for sample stems. Through this exercise, manual log-making crews can improve their decision-making procedure, and gain an understanding of the implications of incorrect decisions. - Harvest planning
With suitable stand population data, the volumes of different log grades that may be recovered from specific timber stands may be determined.
