Equal vs Contribution-Priority Inventory Allocation flow from physical stock and reserve through channel demand, allocation, contribution, decision, and restoration — Use the allocation comparison matrix to allocate one reconciled whole-unit pool.

Hold pool constant

Use the same reconciled physical pool, reserve, channels, forecast horizon, demand caps, contribution estimates, service floors, listing availability, and whole-unit rules. Equal allocation spreads residual stock across unmet channels; contribution priority fills higher-contribution demand first. Compare projected contribution, channel coverage, unmet units, sensitivity, monitoring, and rollback rather than choosing one rule universally. Hold the inventory and forecast packet constant so only the residual-allocation rule changes. Checkpoint 1 in the allocation comparison matrix 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 hold pool constant, keep physical, committed, picked, transferred, damaged, quarantined, inbound, campaign-locked, reserved, and allocatable units separate from demand, contribution, floors, allocation, unmet demand, threshold, conflict, backup, stop rule, and restoration.

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 allocation comparison matrix.

Hold reserve constant

Use the same reconciled physical pool, reserve, channels, forecast horizon, demand caps, contribution estimates, service floors, listing availability, and whole-unit rules. Equal allocation spreads residual stock across unmet channels; contribution priority fills higher-contribution demand first. Compare projected contribution, channel coverage, unmet units, sensitivity, monitoring, and rollback rather than choosing one rule universally. Hold the inventory and forecast packet constant so only the residual-allocation rule changes. Checkpoint 2 in the allocation comparison matrix 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 hold reserve constant, keep physical, committed, picked, transferred, damaged, quarantined, inbound, campaign-locked, reserved, and allocatable units separate from demand, contribution, floors, allocation, unmet demand, threshold, conflict, backup, stop rule, and restoration.

Hold demand constant

Use the same reconciled physical pool, reserve, channels, forecast horizon, demand caps, contribution estimates, service floors, listing availability, and whole-unit rules. Equal allocation spreads residual stock across unmet channels; contribution priority fills higher-contribution demand first.

Hold the inventory and forecast packet constant so only the residual-allocation rule changes.

For hold contribution constant, keep physical, committed, picked, transferred, damaged, quarantined, inbound, campaign-locked, reserved, and allocatable units separate from demand, contribution, floors, allocation, unmet demand, threshold, conflict, backup, stop rule, and restoration.

Hold floors constant

Equal allocation spreads residual stock across unmet channels; contribution priority fills higher-contribution demand first. Compare projected contribution, channel coverage, unmet units, sensitivity, monitoring, and rollback rather than choosing one rule universally. Hold the inventory and forecast packet constant so only the residual-allocation rule changes. Checkpoint 5 in the allocation comparison matrix 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.

Hold pool constant: verification test 1

Create one synthetic counterexample for hold pool constant. Change one availability, lock, reserve, demand, contribution, service-floor, listing, fulfillment, threshold, or evidence field; retain the prior packet; and show equal and priority channel units, allocated total, residual stock, unmet demand, projected contribution, and Block, Review, or Ready effect.

Reconcile the counterexample against a dated physical count, commitments, picks, transfers, damage and quarantine, inbound status, campaign locks, mature order and return aggregates, contribution packet, service obligation, listing and fulfillment state, official platform definition, source version, owner, reviewer, protected baseline, stop trigger, and restored result.

Equal vs Contribution-Priority Inventory Allocation: evidence exercise 1

Reperform hold pool constant 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.

Archive the accepted packet before varying the field. 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.

The exercise remains educational and source-linked.
