Stock planning calculations
Inspect supplied stock cover, reorder thresholds, order-size costs, usage-value groups and per-item landed costs.
How far does stock cover a supplied demand calendar?
Find the first unmet demand day using the supplied arrival timing.
Derive a reorder threshold and compare inventory position
Keep the demand/lead-time threshold separate from current stock and open orders.
Compare order sizes under explicit EOQ assumptions
Compare exact feasible costs beside the continuous EOQ model minimum.
Classify annual usage value with explicit ABC cutoffs
Keep tied items together and show achieved shares when groups cross a cutoff.
Compare per-item landed cost under a selected basis
Compare quantity and total-weight allocations at the item unit-cost denominator.
