Timber price per volume unit:			^³
Waney edge point: ? By definition "waney edged" is: A sawn plank of wood still retaining a natural edge (may include the bark) along one or both sides of the piece of timber. While the "Waney Edge Point" is a distance from a log bottom end to the point where waney edge appears on timber due to logging taper and goes on towards the log small end.
Log Taper per meter(!): ? To be specified per meter/3.3 foot. The taper of a log is the difference in the diameter of a log at its ends, which is due to its natural shape. The diameter gradually becomes less towards a log small end.

The Pi3

Log Batch Cutting Optimization in a sawmill

The Pi3 _(beta) optimizer solves the problem:
What is the best way to cut a given batch of logs into timber of a given size?
The target of optimization is to minimize log consumption and maximize timber yield.

1. The program finds the optimal log diameter for each specific timber size. To reach the goal, a series of log sizes is recalculated and the highest percentage of timber output is set. The process of finding the corresponding log is repeated for each timber size specified by the production program.

2. The optimal cutting pattern for a given timber for a given log is calculated.
