The inventory control models discussed in Chapters 4 and 5 are often labeled independent demand models and MRP is often labeled a dependent demand system. What do the terms independent and dependent mean in this context? 2. What information is contained in a product structure diagram? 3. For the example of Harmon Music presented in this section, determine the planned order release for the slide assemblies. Assume lot-for-lot scheduling. 4. The Noname Computer Company builds a computer designated model ICU2. It imports the motherboard of the computer from Taiwan, but the company inserts the sockets for the chips and boards in its plant in Lubbock, Texas. Each computer requires a total of ninety 64K dynamic random access memory (DRAM) chips. Noname sells the computers with three add-in boards and two disk drives. The company purchases both the DRAM chips and the disk drives from an outside supplier. The product structure diagram for the ICU2 computer is given in Figure 8-6. Suppose that the forecasted demands for the computer for weeks 6 to 11 are 220, 165, 180, 120, 75, 300. The starting inventory of assembled computers in week 6 will be 75, and the production manager anticipates returns of 30
