Requests for copier repairs come in at a mean rate of three per eight- hour day (assume Poisson). Determine:1. The average number of customers awaiting repairs.2. System utilization.3. The amount of time during an eight-hour day that the repairman is not out on a call. 4. The probability of two or more customers in the system.1. There is a Poisson queuing system with the average customer arrival rate of 3 customers per half of hour. This system starts working at 9:0 am. For this system, calculates: iv. The least number of servers needed in the system to ensure that each server would be busy in 70 percent of time at most.A new mall is considering the number of employees on desk dutyinformation, currently only one employee is employed. Based on the informationobtained, it is known that customers will come to the information desk with an average of 20people per hour. It takes an average of 3 minutes to answer the questions. Assumedthat the customer arrival rate follows the Poisson distribution and service timefollowing an exponential distribution. Assume that the employee at the information desk earns Rs50.000,- per hour. The cost of waiting time, if the customer is not satisfied, is IDR 35,000,-per hour of time spent in queue. a. The mall management has decided to consider using two peopleemployee at the information desk. Propose to mall management whether to use aor two employees at the information desk. Explain your answer.

- The parts department of a large automobile dealership has a counter used exclusively for mechanics’ requests for parts. The time between requests can be modeled by a negative exponential distribution that has a mean of five minutes. A clerk can handle requests at a rate of 15 per hour, andthis can be modeled by a Poisson distribution that has a mean of 15. Suppose there are two clerksat the counter.a. On average, how many mechanics would be at the counter, including those being served?b. What is the probability that a mechanic would have to wait for service?c. If a mechanic has to wait, how long would the average wait be?d. What percentage of time are the clerks idle?e. If clerks represent a cost of $20 per hour and mechanics a cost of $30 per hour, what numberof clerks would be optimal in terms of minimizing total cost?8.
