Transportation Terminology Glossary of Terms
Abnormal Demand: Demand in any period that is outside the limits established by management policy. This demand may come from a new customer or from existing customers whose own demand is increasing or decreasing. Care must be taken in evaluating the nature of the demand: Is it a volume change, is it a change in product mix, or is it related to the timing of the order?
Absorption Costing: In cost management, an approach to inventory valuation in which variable costs and a portion of fixed costs are assigned to each unit of production.
