MRP Technique: Determining Net Requirements and Planned Release
Following the example in Figure 11.3.2.2, determine net requirements and planned releases for item ID 4711. Assume an optimum order interval (or optimum length of order cycle) of 3 periods. The production or procurement lead time for item ID 4711 is 2 periods.
Given data or assumptions: a physical inventory of 700 (no safety stock) and the planned gross requirements by period of time as in Figure 11.8.2.1.
