A local machine shop buys hex nuts and molly screws from the same supplier. The hex nuts cost 15 cents each and the molly screws cost 38 cents each. A setup cost of $100 is assumed for all orders. This includes the cost of tracking and receiving the orders. Holding costs are based on a 25 percent annual interest rate. The shop uses an average of 20,000 hex nuts and 14,000 molly screws annually.a. Determine the optimal size of the orders of hex nuts and molly screws, and the optimal time between placement of orders of these two items.b. If both items are ordered and received simultaneously, the setup cost of $100 applies to the combined order. Compare the average annual cost of holding and setup if these items are ordered separately; if they are both ordered when the hex nuts would normally be ordered; and if they are both ordered when the molly screws would normally be ordered.

- A company in Hungary manufactures and sell the product "Mini Bike". The company operates at maximum capacity, producing seven days a week, which makes 50 000 units per year. (To make it simple, we assume that a year has 50 weeks.) The value of a Mini Bike unit leaving production is €100. The cost of capital is estimated to 20%. The cost for holding inventory is 15%, which gives a total inventory carrying cost percentage of 35%. No safety stock is kept in Hungary. Mini Bike is distributed to a wholesaler in the UK, where it's sold to the end customers. There are two transportation alternatives - by rail or by truck: By rail means a dispatch every 14 days. The transportation time is one week. The cost is €4/unit. By truck means a dispatch every week. The transportation time is two days. The cost is €6/unit. In the UK, the wholesaler has a safety stock corresponding to half a week of sales.
