David Christopher is an orthopedic surgeon, who specializes in three types of surgeryhip, knee, and ankle replacements. The surgery mix is 40 percent hip replacement, 50 percent knee replacement, and 10 percent ankle replacement. Partial bills of materials for each type of surgery are shown in the following information.

1. Given that Dr. Christopher is scheduled to do 5 hip replacements, 3 knee replacements, and 1 ankle replacement next week, how many surgical kits and part packages of each type should the hospital have available next week?
2. How many total pints of blood are needed for next week?
3. Design a "mistake-proof" system to ensure each patient gets the correct blood type.
4. What are the implications of a shortage (stockout) of a surgical kit or part package discovered several hours before the operation? What if a part package has a missing part that is not discovered until surgery begins?
