Dynamic Lot-sizing Workbench

How to use Dynamic Lot-sizing Workbench

Compare consecutive-demand batches with exact dynamic programming, then expose every order, ending inventory and setup/holding charge in a conserved schedule.

1. Use the example as the schema; replace its labels and entered model assumptions.
2. Compare consecutive-demand batches with exact dynamic programming, then expose every order, ending inventory and setup/holding charge in a conserved schedule.
3. Calculate, inspect the complete witnesses and limitations, then copy or download the JSON report.

Good to know

• 1–60 periods; each demand, setup and ending-stock holding rate is a nonnegative decimal string no greater than 1 billion. All quantities use one unit and all costs one currency.
• Instant unlimited replenishment before demand; zero opening and terminal stock. No shortages, lead time, capacity, purchase-price changes, tax or uncertainty. Final-period holding is validated but costs nothing because terminal stock is zero.
• Local calculation with no upload, input persistence or outside lookup. Model JSON is limited to 30,000 characters and 10,000 values. Decimal quantities are strings with up to six places; count fields use plain JSON integers. Exact fractions are capped at 8,192 bits. The complete JSON output is limited to 1,000,000 characters; approximate numbers preserve their stored values. Unsupported states fail explicitly.
