Plan where to cut a stem from length, taper, defect positions, product lengths, quality classes, and prices.
Switch between value, yield, and count priorities to compare different bucking strategies on the same screen.
Users can define product lengths, quality classes, and price tables for local markets anywhere in the world.
Input: Stem length 10 m, butt diameter 40 cm, top diameter 20 cm, product lengths 4 m and 2 m, prices 4 m = 80 and 2 m = 38, no defects, objective = value
Output: 4 m x 2 pieces and 2 m x 1 piece, total value 176, yield 100%
Input: Stem length 10 m, product lengths 5 m and 1 m, prices 5 m = 100 and 1 m = 5, objective = count
Output: 1 m x 10 pieces, total value 50, piece count 10
Input: Stem length 10 m, blocking defect from 4.8 m to 5.2 m, product lengths 5 m and 1 m
Output: The 5 m log is excluded by the defect, so the plan falls back to 1 m pieces or waste
Yes. Add rows to the tables and define different standards for each market or buyer.
Value prioritizes price, yield prioritizes saleable length or volume, and count prioritizes the number of pieces.
Yes. Enter them as very short ranges if needed, and use the defect buffer to widen the protected zone.
Yes. Length and diameter units can both be switched. Internal calculations are normalized behind the scenes.
No. This version expects you to define the price table yourself for the market you work in.
The process of cutting a stem into logs with specific product lengths.
The rate at which diameter becomes smaller from the butt toward the top.
The diameter on the thinner end of a log. It is often used for grade checks.
The saw width lost during cutting.
A defect area that makes a candidate cut infeasible when crossed.
A grade such as A, B, or C that is tied to a price table.
