- A well-known coffee shop sells about 300 gallons of its most popular product each week. The estimated cost to store and maintain one gallon of product is $0.50 per week. Each time the coffee shop places an order from its supplier, the following costs are incurred, independent of the size of the order: a $200 delivery fee, $30 unloading and storage, and a $70 transaction fee. Once an order is placed, it arrives exactly 3 work days later. The coffee shop, supplier, and delivery service all operate 7 days per week. a.) What is the optimal (s,Q) policy? b.) What would the (s,Q) policy be if orders were only placed on Fridays with the objective being to cover the demand with no shortages?Mytown’s street department repaves a street every 8 years. Potholes cost $15,000 per mile beginning at the end of Year 3 after construction or repaving. The cost to fix potholes generally increases by $15,000 each year. Repaving costs are $200,000 per mile. Mytown uses an interest rate of 8%. What is the EUAC for Mytown’s policy? What is the EUAC for the optimal policy? What is the optimal policy?The plant manager may purchase a piece of unusual machinery for $10,000. Its resale value after 1 year is estimated to be $3000. Because the device is sought by antique collectors, resale value is rising $500 per year.During an eight-hour shift, 750 non-defective parts are desired as a result of a manufacturing operation. The default operation time is 15 minutes. As the operators of machine are inexperienced, the actual time they take to perform the operation is 20 minutes, and, on average, a fifth of the parts that start to be manufactured are lost. Assuming that each one of the machines used in this operation will not be available for one hour in each shift, determine the number of machines needed.
- Each hour, 100 students want to ride a bus from the student union to Fraternity Row. The admiration places a value of $5/student/hour on each hour that a student is forced to wait for a bus. It costs university $ 10 per bus to send a bus from the student union to Fraternity Row. Assuming that demand occurs at a constant rate, how many buses should be sent each hour from the student union to Fraternity Row?An Soda company sells about 400 gallons of its highly demanded beverage each week. The estimated cost to store as well maintain one gallon of this product is $0.50 per week. Each time the Soda company places an order from its supplier, the following costs are incurred, independent of the size of the order: a $300 delivery fee, $50 unloading and storage, and a $60 transaction fee. Once an order is placed, it arrives exactly 2 work days later. The Soda company, supplier, and delivery carrier all operate 7 days per week. Question: What is the optimal (s,Q) policy?Sturgill Manufacturing Inc. needs to predict the numbers of machines and employees required to produce its planned production for the coming year. The plant runs three shifts continuously during the workweek, for a total of 120 hours of capacity per week. The shop efficiency (the percent of total time available for production), which accounts for setups, changeovers, and maintenance, averages 70% with a standard deviation of 5%, which reduces the weekly capacity. Six key parts are produced, and the plant has three different types of machines to produce each part. The machines are not interchangeable as they each have a specific function. The time to produce each part on each machine varies. The mean time and standard deviation (in hours) to produce each part on each machine are shown below: Mean Time Part Type Machine A Machine B Machine C 1 3.5 2.6 8.9 2 3.4 2.5 8 3 1.8 3.5 12.6 4 2.4 5.8 12.5 5 4.2 4.3 28 6…
- A firm is considering the installation of an automatic data processing unit to handle some of its accounting operations. Machines for that purpose may be purchased for 20,000 or may beleased for 8,000 for the first year and 1,000 less every year now and then until the end of the fourth year.

- The average waiting time of customers over 10 replications obtained from a termination simulation model is shown below Replication / Average waiting time 1 / 3.90 2 / 1.18 3 / 4.88 4 / 4.21 5 / 1.83 6 / 3.77 7 / 1.7 8 / 2.92 9 / 2.39 10 / 2.70 Use alpha = 0.05 for following questions, if needed a) what is the minimum number of sample size required, if the error criterion is 0.75?- Mom-and-Pop’s Grocery Store has a small adjacent parking lot with three parkingspaces reserved for the store’s customers. During store hours, cars enter the lot and useone of the spaces at a mean rate of 2 per hour. For n = 0, 1, 2, 3, the probability Pn that exactly n spaces currently are being used is P0 = 0.1, P1 = 0.2, P2 = 0.4, P3 = 0.3. - Midtown Bank always has two tellers on duty. The Customers arrive at checkouts at an average rate of 40 per hour. A cashier requires an average of 2 minutes to serve a customer.
