Weyerhaeuser's VISION simulator made sawyers test bucking cuts before cutting
Weyerhaeuser put a dynamic-programming log-bucking simulator in the woods, letting sawyers try cuts and see value, adding $100M+ in profit.
Weyerhaeuser Company
the move
Weyerhaeuser's timber value depends on how each felled stem is crosscut into logs and what each resulting log is allocated to, yet buckers historically followed fixed grade-based rules that left money in the woods.
The company built VISION, a decision simulator using dynamic programming, that shows the economic value of a crosscutting and log-allocation plan and lets the bucker or manager alter the decisions and immediately see the change in return.
Because sawyers ran the simulator themselves and watched the payoff of better cuts, the optimized approach took root in practice; the company reported operational benefits exceeding $100 million in increased profits, and the tool changed how timber-processing decisions were made.
why it works
- Wood value is determined at the cut, so bucking is where the money is won or lost.
- A one-size rule cannot capture that the best cut changes with tree, mill and market.
- A simulator turns a mathematical optimum into something a sawyer can see and act on.
- Measured: over $100 million in increased profits from raw-materials return.
what transfers
To get an optimization adopted in the field, put it in the operator's hands as an interactive what-if tool, so the person doing the work discovers the best cut instead of obeying a fixed rule.
what came after
VISION's benefits grew as the tool spread and wood-product markets weakened, making better log use more valuable; it also shifted the firm's management philosophy toward decision support for line workers rather than top-down cutting instructions.
