Backorder Allocation & Fair-Share Fulfillment

Allocation pools that snapshot the available-to-promise quantity of a scarce product and the competing demand lines against it. Five allocation algorithms: strict priority, fair-share / pro-rata, customer-tier waterfall, order-age (FIFO) and ATP-based (safety-stock aware) allocation. Manual override / lock of individual demand lines so a planner can hand-guarantee a quantity to a key account before the engine redistributes the remaining pool to everybody else. Backorder aging buckets and automatic release of open backorders as soon as an inbound receipt registers newly available stock. Available-to-promise (ATP) and capable-to-promise (CTP) checks that project a realistic promise date from scheduled inbound receipts. A what-if allocation simulation wizard that previews the outcome of any algorithm without touching the live allocation. Per-customer fill-rate scorecards aggregated across allocation pools.
