- Galaxy Co. sells virtual reality (VR) goggles, particularly targeting customers who like to play video games. Galaxy procures each pair of goggles for $150 from its supplier and sells each pair of goggles for $300. Monthly demand for the VR goggles is a normal random variable with a mean of 157 units and a standard deviation of 41 units. At the beginning of each month, Galaxy orders enough goggles from its supplier to bring the inventory level up to 140 goggles. If the monthly demand is less than 140, Galaxy pays $20 per pair of goggles that remains in inventory at the end of the month. If the monthly demand exceeds 140, Galaxy sells only the 140 pairs of goggles in stock. Galaxy assigns a shortage cost of $40 for each unit of demand that is unsatisfied to represent a loss-of-goodwill among its customers. Management would like to use a simulation model to analyze this situation. (Use at least 1,000 trials.) (a) What is the average monthly profit (in dollars)?

At the same time, careful attention must be paid to keeping costs down. From historical records, administrators can project the minimum number of nurses required to be on hand for various times of day and days of the week. The objective is to find the minimum total number of nurses required to provide adequate care. Nurses start work at the beginning of one of the four-hour shifts given below (except for shift 6) and work for 8 consecutive hours. Hence, possible start times are the start of shifts 1 through 5. Also, assume that the projected required number of nurses factors in time for each nurse to have a meal break. Formulate and solve the nurse scheduling problem as an integer program for one day for the data given below. (Let x = number of nurses who start work at the beginning of shift t, t = 1, 2, 3, 4, 5.)

With randomly occurring breakdowns, the Poisson probability distribution is used to describe the machine breakdown arrival process. One person from the maintenance department provides the single-server repair service for the six machines. Management is now considering adding two machines to its manufacturing operation. This addition will bring the number of machines to eight. The president of Kolkmeyer asked for a study of the need to add a second employee to the repair operation. The service rate for each individual assigned to the repair operation is 0.40 machines per hour. (a) Compute the operating characteristics if the company retains the single-employee repair operation. (Round your answers to four decimal places. Report time in hours.) W L = q W = ✓ X h × h (b) Compute the operating characteristics if a second employee is added to the…arrow_forward

How does the actual change compare with your estimate? If we resolve the problem with a new right-hand-side of 8 the new optimal objective function value is , so the actual change is a decrease of rather than what we expected in part (b).arrow_forwardBurger Dome sells hamburgers, cheeseburgers, french fries, soft drinks, and milk shakes, as well as a limited number of specialty items and dessert selections. Although Burger Dome would like to serve each customer immediately, at times more customers arrive than can be handled by the Burger Dome food service staff. Thus, customers wait in line to place and receive their orders. Burger Dome analyzed data on customer arrivals and concluded that the arrival rate is 40 customers per hour. Burger Dome also studied the order-filling process and found that a single employee can process an average of 56 customer orders per hour. Burger Dome is concerned that the methods currently used to serve customers are resulting in excessive waiting times and a possible loss of sales. Management wants to conduct a waiting line study to help determine the best approach to reduce waiting times and improve service. Suppose Burger Dome establishes two servers but arranges the restaurant layout so that an…arrow_forward>>>> e 自 A ? ↑ G סוי - C Mind Tap Cengage Learning CENGAGE MINDTAP Chapter 12 Homework: Managing Inventories in Supply Chains Assignment: Chapter 12 Homework: Managing Inventories in Supply Chains Questions Problem 12-70 Algo (Managing Fixed-Quantity Inventory Systems) 6. 7. ng.cengage.com + O C Excel Online Student Work Q Search this course ?

Service clerks’ cross paths, sometimes nearly colliding, while they trace different paths to fill customer orders. If customers order a special combination of toppings on their burgers, they must wait quite some time while the special order is cooked. How would you modify the restaurant’s operations to achieve competitive advantage? Because demand surges at lunchtime, volume flexibility is a competitive priority in the fast-food business. How would you achieve volume flexibility? What are the potential downsides of relying too heavily on automation and standardization in this industry? What data would you want to gather, if any, before making recommendations?arrow_forward
