(using problem 4)

11. a, Determine the planned order release for the motherboards in problem 4 assuming that one uses the EOQ formula to schedule production. Use \\( K=\\$ 180 \\) and \\( h=0.40 \\). b. Using the results from part (a), determine the gross requirements schedule for the DRAM chips, which are ordered from an outside supplier. The order cost is \\( \\$ 25.00 \\) and the holding cost is \\( \\$ 0.01 \\) per chip per week. What order schedule with the vendor results if the EOQ formula is used to determine the lot size? c. Repeat the calculation of part (b) for the add-in boards. Use the same value of the setup cost and a holding cost of 28 cents per board per week. Figure \\( >-0 \\) rroduct structure diagram for ICU2 computer (for problem 4) 4. The Noname Computer Company builds a gaming 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 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 9-6. 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 in week 8 and 10 in week 10. a. Determine the MPS for the computers. b. Determine the planned order release for the motherboards assuming a lot-for-lot scheduling rule. c. Determine the schedule of outside orders for the disk drives
