Thomas Built Buses (TBB) manufacturers yellow school buses at its facility in High Point, NC. TBB orders its windshields from a specialty vehicle glass supplier. Weekly requirements for the windshields are normally distributed with a mean of 167 units/week and standard deviation of 88 units/week. Lately, the supplier has been unreliable with its deliveries. TBB estimates the lead time is normally distributed with mean 3 weeks and standard deviation 2 weeks. TBB orders the windshields at a unit cost of $2314. The annual cost of carrying inventory at the plant is 30% of the purchase cost per unit per year. TBB reviews its windshield inventory continuously. Assume 52 weeks/year, 7 days/week, and 364 days/year.
