Dan's Independent Book Store is trying to decide how many copies of a book to purchase at the start of the upcoming selling season. The book retails at $28.00. The publisher sells the book to Dan at $20.00. Dan will dispose of all of the unsold copies of the book at 50% off the retail price, at the end of the season. Dan estimates that demand for this book during the season is normal with a mean of 1000 and a standard deviation of 250. The publisher is thinking of offering the following scheme to Dan. At the end of the season, they will buy back unsold copies at a pre-determined price of $17.00.

You have been asked to help a manufacturing firm that produces a variety of specialty components for local auto speed shops. The firm orders a number of components from suppliers, but the one they have asked you to analyze is special welding rod. Historical data suggests daily consumption of these rods can be modeled by a normal distribution with a mean and standard deviation of 42.3 and 5.1 bolts per day, respectively. The rods come in boxes of 5 rods/box, and the supplier will only ship in box quantities. It takes 2 days to receive an order from the supplier. You may assume that the daily demands are independent and identically distributed, and that inventory position is always known (i.e., continuous review). 1. The current policy is the order thirty boxes from the supplier when inventory position reaches ten boxes. What is the long run fraction of stock outs associated with the current strategy? 2. Assume the cost to place an order is $5 and holding is estimated to be…

= A small manufacturing facility stocks a single-use filter, part SUF100, for their production process. It costs the manufacturer $1.50 per filter to purchase and $100 per order placed. They use a holding cost of 28% annually. Monthly demand for SUF100 follows a normal distribution with u 280 and σ = = 77. The parts arrive five months after an order is placed. If a stockout occurs, the demand is backlogged, not lost, and costs the production facility $12.80 per part backordered. 1. Find the optimal order quantity and reorder level to minimize average annual cost of holding, setup, and stockout. 2. What is the average annual cost of holding, setup, and stockouts, when the Q,R-policy in part 1 is used?
