STOCK FIT

Stock expiry allocation — required compatible stock units scenarios.

How does changing required compatible stock units affect stock expiry allocation when the other inputs stay fixed?

What this decision changes

Full required pieces must fit usable stock. Aggregate area or length alone cannot prove a feasible cut or roll allocation. Method basis: Eligible stock is assigned by earliest entered expiry date. Entries use one common quantity basis; product compatibility and actual condition must be checked separately.

The focus is required compatible stock units. All other shared inputs remain fixed for each evaluated range.

Read the evaluated results

Look for jumps in purchased stock and rejected fits. The rows show actual evaluated allocations, not an assumption that every intermediate size will behave identically.

Replace every illustrative baseline measurement and selected product value with the inputs for your actual task.
Enter a comparison range on the focused input's stated unit and quantity basis.
Review rejected combinations and use the exact detail lines to distinguish measured demand from whole purchases.
Open an evaluated scenario in the full calculator to save its original inputs and quantity breakdown to a browser material project.

Keep the comparison within scope

Permitted orientation, complete-run requirements and reserved cut losses remain supplied inputs; sampled layouts do not promise a globally optimal cut plan.

Eligible stock is assigned by earliest entered expiry date. Entries use one common quantity basis; product compatibility and actual condition must be checked separately.

Dimensions, quantities, prices, timing and product properties are supplied by you. This tool does not select construction specifications or assess structural, electrical or hydraulic suitability.

Only the listed samples are evaluated. Intermediate values, alternate constraints and global cutting optimality are not inferred from the graph.
