Single-item Time-phased Material Plan

How to use Single-item Time-phased Material Plan

For each period, consume demand after scheduled receipts, then add enough planned receipts to retain the declared safety balance. Lot-for-lot or fixed multiples control size, and an integer lead time shifts releases, including visible pre-horizon requirements.

1. Enter model json (schema and units below).
2. Choose the stated convention and check the units and supported model.
3. Calculate, inspect the result, then copy or download it.

Good to know

• 1–100 numbered periods, whole units up to 1,000,000 per field, projected stock at most 1,000,000,000, lead time 0–100 periods. One independent item only; no BOM explosion, capacity, uncertain lead times, holidays or purchasing action.
• Local calculation only; no input persistence or external lookup. Text/JSON is limited to 30000 characters and output to 1000000 characters. Numeric model inputs and precision/work limits are stated on this page. Approximate JSON numbers retain full stored values; exact arithmetic outputs retain decimal or fraction strings. Unsupported states fail explicitly.
• Educational user-assumption arithmetic only. No live prices, laws, tax rules, quotes or financial advice.
