Scenario for problems 2 through 4 The following serial manufacturing process consisting of three workstations needs to produce 1000 parts each day. 1 2 3 di dz dz 2. The defect rates are di=3%, dz=5%, and dz=7%. a) If all defects are scrapped, how many parts need to be started to achieve the required output each day? b) Suppose the per part scrap costs at workstations 1, 2, and 3 are $5, $10, and $15, respectively. What is the total daily scrap cost to produce the 1000 parts/day requirement
