Fixed versus competing bundle inventory

Last updated: 2026-07-31

Written and reviewed by Seller Profit Guard Editorial Team.

A fixed bundle uses the minimum component quotient under one recipe. Competing bundles add an allocation decision because the same shared units can support different parents at different recipe rates. Compare the scenarios only after normalizing inventory state, location, unit, variant, timestamp, reservations, commitments, and recipe versions.

two-scenario capacity matrix from component states and recipes through fixed or competing capacity, bottlenecks, review, and restoration — This original diagram explains a normalized bundle comparison with synthetic component data.

Normalize state

Use the same Available definition. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Prevent field drift. At checkpoint 1, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Normalize location

Keep compatible component pools. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Transfers are separate. At checkpoint 2, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Normalize recipe version

Bind each parent variant to current quantities. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Record effective dates. At checkpoint 3, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Compare fixed constraint

Scenario A uses minimum quotient only. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

No allocation choice. At checkpoint 4, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Compare shared constraint

Scenario B consumes one pool across parents. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Sequence matters. At checkpoint 5, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Compare tied bottlenecks

A/C tie in fixed; shared/unique-Y tie in competing. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

List all. At checkpoint 6, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Compare sensitivity

A reservation and an X priority unit have different effects. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Show marginal change. At checkpoint 7, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Compare decision authority

Neither result authorizes assembly, listing, or purchase. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Assign owners. At checkpoint 8, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Compare monitoring

Fixed checks deductions; competing checks mix and sequence. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Review variance. At checkpoint 9, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Choose the correct model

Use fixed math for one recipe and allocation scenarios for shared pools. The two-scenario capacity matrix records item and variant identifiers, location, inventory state, timestamp, unit, reservation and commitment convention, recipe version, transformation, owner, reviewer, exception, and prior accepted value needed for a normalized bundle comparison.

Do not collapse them. At checkpoint 10, reperform both fixtures, identify the changed quotient or allocation term, list every tied bottleneck, and state which demand, pricing, purchasing, assembly, fulfillment, or privacy conclusion remains outside the calculator.

Separate capacity from demand, pricing, safety stock, purchasing, assembly, allocation, and fulfillment. Control 8 defines a pass condition, evidence owner, independent reviewer, correction deadline, sensitivity range, monitoring signal, stop condition, and restoration trigger for a normalized bundle comparison.

Arithmetic cannot authorize. Apply it while keeping Available, additional reservations, unreflected commitments, recipes, fixed capacity, competing allocation, thresholds, and operational authority separate.

Fixed vs Competing Bundle Capacity: privacy and restoration control

Use aggregates, protect source rows, monitor deductions, retain prior settings, and define rollback. Control 9 defines a pass condition, evidence owner, independent reviewer, correction deadline, sensitivity range, monitoring signal, stop condition, and restoration trigger for a normalized bundle comparison.

Public private data is prohibited. Apply it while keeping Available, additional reservations, unreflected commitments, recipes, fixed capacity, competing allocation, thresholds, and operational authority separate.

Evidence boundary for a normalized bundle comparison

The fixed-bundle fixture uses three compatible components at one location. After additional reservations and commitments, A has 100 allocatable units and requires two, B has 70 and requires one, and C has 200 and requires four. Capacities are 50, 70, and 50, so maximum complete bundles equal 50 and A plus C are tied bottlenecks. The result is 10 bundles above the default 40-bundle control. The competing-bundle fixture starts with 140 allocatable shared units. Thirty priority Bundle X units consume 60 shared units because X requires two each, or 42.86 percent of the shared pool. The remaining 80 shared units and 80 allocatable unique-Y units each support 80 Bundle Y units, creating a tied bottleneck. The allocation stays 17.14 percentage points below the default 60 percent priority-utilization ceiling, and both 60-day evidence windows are 15 days above the default 45-day evidence floor.

The packet demonstrates entered complete-set arithmetic and one priority allocation under a dated policy. It cannot prove demand, optimal mix, compatible future receipts, correct safety stock, purchase quantity, fulfillment eligibility, accounting treatment, customer outcome, or the correct business action.

Release, monitor, and restore the two-scenario capacity matrix

Block non-finite or invalid quantities, recipes, dates, confirmations, scope, compatibility, privacy, copied scenarios, or conflicts, and mask every derived output. Review insufficient evidence, overcommitment, infeasible priority, excessive shared-component utilization, or capacity below threshold. Ready clears only the entered worksheet.

Before indexing or operational use, preserve evidence and rollback artifacts; run typecheck, unit, integration, build, content, similarity, SEO, image, link, mobile, strict-route, deployment, and live checks; then compare actual component consumption without claiming same-period causality.
