Let’s take the example of the retail chain for sales of 40-inch HDTV sets. The building block for the supplier schedule are the demand plan (sale forecast) and the dependent replenishment forecast (planned shipments) for the 40-inch TV unit in the Los Angeles store. (See Exhibit 2.) The planned shipment are calculated accounting for the planned safety stock, the presentation minimums, delivery schedules, and order minimums and multiples. The store-level DRP system calculates similar planned shipments for all stores service by the DC. The timing and quantities of the sum of the planned shipment to all store becomes the dependent demand forecast for this DC for the HDTV
