The demand for an item that is unrelated to the demand for other items. Demand for finished goods, parts required for destructive testing, and service parts requirements are examples of independent demand. See: dependent demand.
Models for the management of items whose demand is not strongly influenced by other items managed by the same company. These models can be characterized as follows: (1) stochastic or deterministic, depending on the variability of demand and other factors; (2) fixed quantity, fixed cycle, or hybrid -(optional replenishment). See: fixed reorder cycle inventory model, fixed reorder quantity inventory model, optional replenishment model.
