Please do not give solution in image format thanku 969) During the campus Spring Fling, the bumpercar amusement attraction has a problem of carsbecoming disabled and in need of repair. Repairpersonnel can be hired at the rate of $20 per hour,but they only work as one team. Thus, if one personis hired, he or she works alone; two or three peoplework together on the same repair.One repairer can fix cars in an average time of 40minutes. Two repairers take 22 minutes, and threetake 18 minutes. While these cars are down, lostincome is $35 per hour. Cars tend to break down atthe rate of 1.80 per hour.Management is trying to decide how many repairpersons to hire, and has asked you for cost data.a.What is the total hourly cost with one repair person?(Round your intermediate calculations and finalanswer to 2 decimal places.)

We are analyzing the performance of four different machines, all subjected to the same workload. We have calculated the average Cycle Time (CT) and Work in Progress (WIP) for these machines. Which machine has the smallest effective variability? Machine 1: CT= 5 hours , WIP= 15 units Machine 2: CT= 10 hours , WIP= 30 units Machine 3: CT= 20 hours , WIP= 60 units Machine 4: CT= 40 hours , WIP= 120 units
Virginia's Ron McPherson Electronics Corporation retains a service crew to repair machine breakdowns that occur on an average of λ = 4 per 8-hour workday (approximately Poisson in nature). The crew can service an average of μ = 6 machines per workday, with a repair time distribution that resembles the negative exponential distribution. a) The utilization rate of this service system (round your response to two decimal places)
Virginia's Ron McPherson Electronics Corporation retains a service crew to repair machine breakdowns that occur on an average of λ = 2 per 8-hour workday (approximately Poisson in nature).

Fatema, Mariam, and Layan are three dental hygienists who work for Dr. Amnah at Family Dentistry. All three hygienists do pretty much the same thing every day. On an average, they see 12 people every day for regular teeth cleaning which involves cleaning, flossing, and normal checkup. Dr. Amnah, on the other hand, has quite unpredictable job. She has to respond to all types of teeth-related emergencies including having to do surgeries. All three hygienists always try to help each other out, have a very good attitude in general toward each other, and keep each other informed about matters that are relevant to them and to Dr. Amnah. Fatema specifically takes on the role of attending all community-related voluntary meetings and functions where Family Dentistry may have a stake or are asked for involvement. On her own time, she keeps up on all dental regulations and business-related news that may have an impact on the firm. Mariam speaks up and offers constructive suggestions regarding…

A company that makes shopping carts for supermarkets and other stores recently purchased some new equipment that reduces the labor content of the jobs needed to produce the shopping carts. Prior to buying the new equipment, the company used 6 workers, who together produced an average of 70 carts per hour. Workers receive $18 per hour, and machine cost was $30 per hour. With the new equipment, it was possible to transfer one of the workers to another department, and equipment cost increased by $11 per hour, while output increased by 5 carts per hour. a. Compute labor productivity under each system. Use carts per worker per hour as the measure of labor productivity. (Round your answers to 3 decimal places.) b. Compute the multifactor productivity under each system. Use carts per dollar cost (labor plus equipment) as the measure. (Round your answers to 3 decimal places.) c. Comment on the changes in productivity according to the two measures. (Round your intermediate calculations…
