In a company two mechanics maintain two very important machines in a production process, which usually break down on average every 16 hours. This time between breakdowns has an exponential distribution. A mechanic spends on average 10 hours repairing a machine (time with exponential distribution). Determine how much time a machine spends on average in the system.

- A copier is able to operate for an average of 200 hours between repairs, and the mean repair time is two hours. Determine the availability of the copier.Failsafe Textiles employs three highly skilled maintenanceworkers who are responsible for repairing the numerous in-dustrial robots used in its manufacturing process. A workercan fix one robot every 8 hours on average, with an exponen-tial distribution. An average of one robot fails every 3 hours,according to a Poisson distribution. Each down robot coststhe company $100.00 per hour in lost production. A newmaintenance worker costs the company $80.00 per hour insalary, benefits, and equipment. Should the manager hireany new personnel? If so, how many people? What would yourecommend to the manager, based on your analysis?Safety regulations require that the time between airplane takeoffs (on the same runway) will be at least 3 minutes. When taking off, the run time of an airplane on the runway is 33 seconds. Planes are on average waiting 6 minutes and 48 seconds for takeoff. On average there are 16 planes taking off per hour. How many planes are either on the runway or waiting to take off? Round your answer to 2 decimal places.
- During a plant start-up, the operators should go through the start up sequence quickly to reduce the downtime and increase the profitability of the plant. there should be as few operators as possible near the column to ensure that any major accidents will result in lower injuries and fatalities. the operators should fully depend on the automated start up sequence without any intervention to increase the smoothness of the start up. Othere should be as many operators as possible near the column to ensure that any operational emergencies can be safely and quickly managed.Blue Lotus is a bike shop located near a beach resort, which rents its bikes to guests staying in the resort. When a customer requests to rent a bike and no bikes are available (they are either with another customers or being cleaned for rental), customer waits until a bike is available. Once a bike rented out to a customer, the customer keeps it for an average of 1 day. Upon return, the bike is cleaned and tuned-up, which takes half a day (0.5 day). Suppose Blue Lotus has 7 bikes, and demand for bike rental is 4.1 per day. What is the average amount of time a customer waits to receive a bike? (Hint: From the perspective of customer waiting time, 0.5 day of cleaning time would be part of the processing time" so, p = 1+0.5 =1.5 days. Assume CVa = CVp = 1 in your calculations). O 1.197 days O2.134 days O 0.761 days O 5.380 daysToolco operates a machine shop with 22 machines. On the average, a machine breaks down every 2 hours. It takes an average of 12 minutes to complete a repair. When a machine breaks down, one of four repairpersons is called upon to do the repair. Both the time between breakdowns and the repair time are exponential. Toolco is interested in analyzing this situation and knowing the number of repairpersons needed to keep the shop running "smoothly." A = 12 = 0.5 breaks down per hour μ = 60/12 = 5 breaks down per hour System limit = K = 22 machines Source limit= K = 22 machines R = 1, 2, 3, 4. (M/M/R: GD/ K /K),
- Ashley’s department store in Kansas City maintains a successful catalog sales department in which four clerk takes orders by telephone. If four clerks are occupied on four-lines, incoming phone calls to the catalog department are answered automatically by a recording machine and asked to wait. As soon as the clerk is free, the party that has waited for the longest is transferred and answered first. Calls come in an average of 3 minutes. The clerk is capable of taking an order in an average of 10 minutes. Calls tend to follow a Poisson distribution, and service times tend to be exponential. a. λ= μ= b. Calculate P0 c. How many callers, on average, are waiting to place an order under the current operating system?Patients walk in to a doctor’s office every 63 minutes with a standard deviation of 32 minutes on the average. The average examination time is 37 minutes with 32 minutes standard deviation.

The number of students in the building is 100, on average. B. Students spend an average of 120 minutes in the building. C. The arrival rate at the building is 83.33 students per hour. D. The building must have at least 5 classrooms. E. None of the answers are correct.A crew of mechanics at the Highway Department Garage repair vehicles that break down at an average of λ = 7.5 vehicles per day (approximately Poisson in nature). The mechanic crew can service an average of μ = 10 vehicles per day with a repair time distribution that approximates an exponential distribution. How much of that time is spent waiting for service?Patients enter an intensive care unit at the rate of 7 patients per day. On average, a patient spends 3.1 days in the intensive care unit. On average, how many patients are in the intensive care unit? Note: Round your answer to 2 decimal places.
