Contribution-Weighted Inventory Allocation Example flow from physical stock and reserve through channel demand, allocation, contribution, decision, and restoration — Use the priority allocation worksheet to allocate one reconciled whole-unit pool.

Open priority fixture

Using the same 270 allocatable units and 40-unit channel floors, assign the remaining stock by USD 20, USD 15, and USD 10 contribution per retained unit. The result is 150, 80, and 40 units, with 100 unmet units and USD 4,600 modeled contribution while the lowest-contribution channel retains its service floor. Use contribution priority after floors rather than renaming the equal-allocation fixture. Checkpoint 1 in the priority allocation worksheet records physical SKU identity, unit of measure, cutoff, availability exclusions, reserve purpose, forecast horizon, source version, owner, reviewer, accepted formula, authorization boundary, and restoration before interpretation.

For open priority fixture, preserve the three service floors, rank only verified contribution per mature retained unit, fill residual demand in deterministic order, keep every channel below its demand cap, retain whole-unit rounding, and expose the lowest-priority channel's service and campaign risk.

Use invented or approved SKU-level aggregates only. Exclude private emails, buyer identities, addresses, order rows, payment details, bank records, credentials, invoices, contracts, and raw inventory or order exports from the public priority allocation worksheet.

Contribution-Weighted Inventory Allocation Example: evidence exercise 1

Reperform open priority fixture with invented equal and contribution-priority packets. Hold SKU identity, physical count, exclusions, reserve, forecast dates, channel demand, contribution definitions, service floors, listing and fulfillment eligibility, and whole-unit rules constant where a clean strategy comparison requires them.

Explain allocatable units, each channel allocation, residual units, channel coverage, unmet units and percentage, projected contribution, decision, sensitivity driver, monitoring trigger, authorized-owner boundary, stop condition, and restoration path.
