Set your policy
Whole units; lost demand is not backlogged. End-of-day review places at most one fixed-size order when closing stock plus outstanding orders is at or below the reorder point. This is neither continuous review nor an order-up-to policy.

Read the outcome
One seeded sample path, not an estimate of expected policy service. Compare seeds before drawing a general conclusion. No inventory or ordering costs are modeled: better fill alone does not establish an economic optimum.
- Demand fill rate
- Unmet demand
- Orders placed
- Ending stock
Stock and arrivals
Line: closing stock; circles: morning arrivals. Exact values and decisions are in the ledger below.
Compare a policy on exactly the same demand path
Only reorder point and order quantity change. The horizon, demand inputs and seed stay fixed. This isolates service and inventory consequences; neither policy is declared economically best.

Daily stock ledger
All quantities are units. On order and position are measured after arrivals/sales, before a new order. Next due is a day number (— means none). Final-day orders continue beyond this reporting window. Scroll the exact table horizontally on a small screen.
| Day | Opening | Arrivals | Demand | Sales | Unmet | Closing stock | On order before decision | Position before decision | Ordered | Next due day | Decision |
