A 28‑year‑old woman with a known history of von Willebrand disease presents to the ICU with brisk, persistent epistaxis and hematemesis after a night of repeated nosebleeds.

If we increase the salvage value of an item and hold all other costs unchanged, what happens to the optimal order size in the newsvendor model?

Chesapeake Bay Lumber company is selling a new product through a single retailer – Home Pepot.  Demand for the product is equally likely to be 1, 2, 3, 4, 5, or 6 units per week. Production cost for the supplier is $100, and the retail price to the final customer is $300. The salvage value is 0, items left over at the end of the week are discarded, and orders are placed once per week. If the manufacturer and the retailer were part of the same organization and kept all supply chain profit, how many units would be produced?

Rank all of your team’s supply chain risk categories from 1-5 (1-4 for teams of 4 people) where rank #1 is the most critical risk, rank #2 is the second most critical risk, etc.? Explain what evidence most influenced the ranking of the top 2 risk categories?

When considering the EOQ framework, the fixed holding cost is:

If the cost of under-ordering is less than the cost of over-ordering, and the demand distribution is symmetric then when the level of uncertainty in demand increases (higher standard deviation or variance), what happens to the optimal order size in the newsvendor model?

Activity times are known for a process that has only one step but delays happen sometimes due to quality issues. This results in a waste factor of 20%. What can we say about the comparison between theoretical and effective capacity?

Assume you have a 3-step process using 3 machines with deterministic activity times of 15 min, 20 min, and 15 min respectively and it costs $10 to add a machine at any step. How much can you increase capacity if you invest $20 = ($10*2) to add machines?
