A newsvendor orders the quantity that maximizes expected profit for two products, X and Y. The critical ratio for both products is .8. The demand forecast for both products is 9000 units and both are normally distributed. Product X has more uncertain demand in the sense that it has the larger standard deviation. Of which of the two products does the newsvendor order morea. Product X because it has less certain demand. b. Product Y because it has more certain demand. c. The order quantities are the same because they have the same critical ratio. d. More information is needed to determine which has the higher order quantity.

15. Applied Machines produces large test equipment for integrated cireuits. The machines are made to order, so the production rate varies from month to month. Before shipping, each machine is subject to extensive testing. Based on the tests the machine is either passed or sent back for rework. During the past 20 months the firm has had to rework the following numbers of machines: Number Number Number Number Month Produced Reworked Month Produced Reworked 23 28 16 3 3 11 17 3 12 4 1 13 14 2 14 41 15 16 18 32 4 29 19 17 18 33 46 21 4 5 12 1 19 7 10 7 1 20 29 7 Determine if the process was in control for the 20-month period using a stan- dardized version of the p chart.

d) A company can produce three products A, B and C. the products yield a contribution of Kshs.8, 5 and 10 respectively. The products use a machine which has 400 hours capacity. Each unit of the product uses 2, 3 and 1 hour respectively of the machines capacity. There are only 150 units available in the period of a special component which is used singly in product A and C. Only 200kgs of a special alloy is available in the period. The usage of special alloy is 2kgs per unit and 4kgs per unit respectively. There is an agreement with a trade association to produce no more than 50 units of product B in the period. Advise the company on the production plan that will maximize contribution.

6. The demand for a particular part called SKU 005 is 1,500 units a year. The cost of one SKU 005 is $40.00. It costs $50.00 to place an order for SKU 005, and the user of SKU 005 has a per year inventory carrying cost of 25% of unit cost. Assume 250 working days in the year where SKU 005 is used. (Noteshaper: Scenario #26) а. What is the combined annual holding and ordering cost of an order size of 200 units for SKU 005? b. How many of SKU 005 should be ordered, to minimize combined ordering and holding costs? c. The vendor who sells SKU 005 has just offered a 5% discount for orders of 500 or more. Now how many should be ordered? d. Once the purchasing manager for SKU 005 places an order, the vendor requires 7 working days to deliver that order. What should be the purchasing manager's reorder point?
