- Drivers who come to get their licenses at the Department of Motor Vehicles have their photograph taken by an automated machine that develops the photograph onto the license card and laminates the complete license. The machine requires a constant time of 4 minutes to prepare a complete license. The interarrival time between two drivers is 6 minutes distributed exponential. a) What type of queuing model this system follow ? b) Determine the average length of the waiting line. c) Determine the average waiting time.A local fast-food restaurant wants to analyze its drive-thru window. At this time, the only information known is the average number of customers in the system (4.00) and the average time a customer spends at the restaurant (1.176 minutes). What are the arrival rate and the service rate?1.) What does not decrease system utilization? increase in arrival rate increase in service rate increase in the number of servers decrease in the service time 2.) When a customer is waiting in line and decides to leave a system, this is known as anti-queuing reneging jockeying hesitating

Autos arrive following a Poisson distribution at the rate of 1212 per hour. Renuka wants to? know: ? a) The average wait time in the line ?= __________(round your response to two decimal? places). ? b) The average number of customers waiting in the line ?= ________ cars ?(round your response to two decimal? places).A small COVID testing location has a single reception desk. The time between two arriving people equals on average 3.5 minutes (Poisson arrival process). Exactly 27 people per hour can be helped at the desk. What is the average number of clients waiting for their turn (so excluding clients who are actually being helped)? (Round your answer to two decimals)One field representative services 5 customers for a computer manufacturer. Customers request assistance at an average (Poisson-distributed) rate of once every 1.5 working days. The field representative can handle an average (Poisson-distributed) of 1.0 call per day. Determine: Use Table 1. a. The expected number of customers waiting. (Round "X" value to 2 decimal places. Round your answer to 3 decimal places.) Expected number of customers waiting b. The average length of time customers must wait from the initial request for service until the service has been completed. (Round your answer to 2 decimal places.) Average length of time days c. The percentage of time the service rep will be idle. (Round your answer to 1 decimal place.) Percentage of Idle time d.
