The average expense of keeping inventory for an integrated circuit producer is 48 percent.What inventory keeping expense (in $) does an object cost $300 and has an estimated one-month inventory supply?
6000 units of a part are needed every year. Currently, this part is manufactured internally. Each production run costs 500 dollars to set up. The part costs 5 dollars. The carrying cost is 10% per year. The company has the option of ordering this part from another company. This would increase the part’s cost to 6 dollars, although the fixed cost of ordering would be low at 300 dollars per order. Should the company continue manufacturing the part, or order it? Show your calculations.
