2.12: A computer recycler sells computer enclosures to a computer remanufacturer. To meet monthly expected demand, the remanufacturer needs 2,000 enclosures. The recycler utilizes a four-step disassembly process with scrap rates given as follows : d1=0.08d2=0.05d3=0.05 and d4=0.03. How many computers must the recyeler receive each month in order to meet the remanufacturer's demand? 2.13: Consider a simple three-step manufacturing process as illustrated in the given figure. Assuming that demand is 1,000 units, what is the required input to meet demand. You'll note that the required input is the same if the scrap rates are reversed for processes 1 and 3 . Assume that the serap cost is $5 at process 1,$10 at process 2 , and $15 at process 3 . The defective rates are 3%,5% and 7% respectively. Compute the to-tal scrap cost for the given system and the system where the scrap rates are reversed. Which system would be preferred ( dl=3%&d2=5%&d3=7% ) ? 2.16 : Given the figure below, operation 4 represents a rework operation on pats that fail in section upon completion of operation 2 ? dl=5%d2=5%d3=10%d4=2% \& 5000 Units
