LEE is considering to manufacture many of the components. The cost to set up for producing a standard component is approximately $200 (considering labor, testing facilities, etc.). Once set up they can produce at a rate of approximately 20 units /day (4,000 units per year) at a cost of $100 each. Daily demand is forecast at 15 units. If the firm uses 30% annual rate of inventory value for holding inventory:
01. What is the inventory rate (%) of the component? (3 pts.)
02. What is the most economical lot size to produce (i.e., ERL)? (4 pts.)
03. What is the total inventory cost/year? (=total setup cost + total carrying cost) (4 pts.)
04 What is the estimated number of days to spend for production (in days) during the production run cycle? (3pts.)
