1. [40 pоints] Cоnsider а 4-periоd lot sizing problem with the demаnd vector D = (20,45,30,15). The fixed production setup cost is $100, the unit vаriable production cost is $8, and the unit inventory holding cost is $3 per period. Assume that the initial inventory level and the ending inventory level must be zero. Find the optimal lot sizing schedule for this setting I. [20 points] using the Wagner-Whitin Algorithm. II. [20 points] using the Part Period Balancing Heuristic. 2. [30 points] A bakery bakes fresh doughnuts every morning. Production cost is 40 cents per doughnut, and they are sold for 75 cents each. Unsold doughnuts at the end of the day are purchased by a charity kitchen for 10 cents each. The daily demand for doughnuts is a random variable with uniform distribution over the range of [10,75]. I. [15 points] How many doughnuts should the bakery make at the start of each day? II. [15 points] Assume there is a unit loss-of-goodwill cost of 20 cents for unmet demand. How many doughnuts should the bakery make at the start of each day? [30 points] A publisher sells books to Barnes & Noble at $12 each. The marginal production cost for the publisher is $1 per book. Barnes & Noble prices the book to its customers at $24 and expects demand over the next two months to be normally distributed, with a mean of 20,000 and a standard deviation of 5,000. Barnes & Noble places a single order with the publisher for delivery at the beginning of the two-month period. Currently, Barnes & Noble discounts any unsold books at the end of two months down to $3, and any books that did not sell at the full price sell at this price. I. [15 points] How many books should Barnes & Noble order? What is its expected profit? How many books does it expect to sell at a discount? What is the profit that the publisher makes, given Barnes & Noble’s actions? II. [15 points] Under a new plan, the publisher refunds Barnes & Noble's $5 per book that did not sell at the full price. As before Barnes & Noble will sell the unsold books for $3 each at the end of the two-month period. Under this plan how many books will Barnes & Noble order? What is the expected profit for Barnes & Noble? How many books are expected to be unsold at the full price? What is the expected profit for the publisher?
