The White Tooth Device Company is a manufacturer of high-end electric toothbrushes. For each toothbrush, there is a sequence of assembly steps performed by five workers. Each worker does two tasks. Inventory buffers are allowed between workers. (a) What is the capacity and cycle time of this process? (b) What is the idle time of each worker if the process operates at full capacity? (c) Suppose two workers could be hired, F and G, and they take the same time to complete tasks as the current five workers. F and G can be assigned to work on the same pair of tasks as one of the current workers. For example, F could be assigned tasks T1 and T2 (just like worker A) while G is assigned T5 and T6 (just like worker C). They cannot be assigned tasks that are currently assigned to two workers. For example, F cannot be assigned to tasks T2 and T3 (because they are currently being done by workers A and B). What is the capacity of this process with workers F and G included?
The current level of resources is or is not Sufficient to satisfy a demand of 8 orders per hour because the process capacity is greater or less than demand.

If a production process has a bottleneck cycle time of 48 minutes/item, what is the maximum daily capacity of the system, assuming the company operates two, 8-hour shifts? Enter an integer value.
Mack’s guitar fabrication shop produces low cost, highly durable guitars for beginners. Typically, out of the 100 guitars that begin production each month, only 80 percent are considered good enough to sell. The other 20 percent are scrapped due to quality problems that are identified after they have completed the production process. Each guitar sells for $300. Because some of the production process is automated, each guitar only requires 10 labor hours. Labor is paid at $10/hour, materials cost is $40/guitar, and overhead is $2,000. a) Calculate the labor and multifactor productivities. b) After some study, the operations manager recommends 3 options to improve the company’s multifactor productivity: (1) increase the sales price by 10 percent, (2) improve quality so that only 10 percent are defective, or (3) reduce labor, material, and overhead costs by 10 percent. Which option has the greatest impact on the multifactor productivity measure?
In order to produce 1000 units of X in a week  units X is scheduled weekly for Operation B (due to 5% scrap ratio)  units X is scheduled weekly for Operation A (due to 2% scrap ratio) Based on your answer in part a, find the number of machines required to produce 1000 units of X per week.  The total time required to perform Operation B = minutes per week  The total time required to perform Operation A = minutes per week H= Available Time in a week = minutes /week Thus FA = . FB = . Since both of the operations A and B are performed on the same machine  machines are required
Suppose the daytime processing load consists of 70% CPU activity and 30% disk activity. Your customers are complaining that the system is slow. After doing some research, you have learned that you can upgrade your disks to 2.5 times as fast as they are currently for $5,000 or you can upgrade your CPU to make it 1.5 as fast for $8000. a) Which would you choose to yield the best performance improvement for the least amount of money? b) Which option would you choose if you don't care about the money, but want a faster system?

Kevins Shampoo company makes four kinds of shampoo: rose, lemon, ginger, and tea tree. The demand for the four scents are 191, 164, 92 and 74 kg per hour respectively. The production process can produce any shampoo at the rate of 581 kg per hour, but 2 hours are needed to switch between scents. The process doesn’t produce any shampoo during switchover times. Kevin wants to choose a production schedule that (i) cycles repeatedly through the four scents, (ii) meets the required demand and (iii) minimizes the amount of inventory held. (please round your answers to 2 decimal places) 1.How many kg of rose shampoo should Kevin produce before switching over to another scent？ 2.Kevin needs to buy coconut oil to make her shampoo. She needs 1401 kg of coconut oil per day on average. The supplier charges a EUR 77 delivery fee per order (which is independent of the order size) and EUR 5.13 per kg.
