A self-service store employs one cashier at its counter. Nine customers 'arrive on an average
every 5 minutes while the cashier can serve 10 customers in 5 minutes. Assuming Poisson
distribution for arrival rate and exponential distribution for service time, find
1. Average number of customers in the system.
2. Average number of customers in the queue or average queue length.
3. Average time a customer spends in the system.
4. Average time a customer waits before being served.
A.1
Let a queuing system have the Kendall model (M/M/1) : (GD/infinity/infinity). Assume A < µ. Does W, for the
service discipline FIFO equal W, for the service discipline SIRO?
O I have no idea.
no
yes
It cannot be determined.
In modeling a waiting line problem, 1/ μ and 1/ λ represent the mean values of:
a. Arrival time and service rate respectively (i.e. in that order).
b. Inter-arrival time and service time respectively.
c. Service time and inter-arrival time respectively.
d. Wait time and queue time respectively.

- Many of a bank's customers use its automatic teller machine to transact business after normal banking hours. During the early evening hours in the summer months, customers arrive at a certain location at the rate of one every other minute. This can be modeled using a Polsson distribution. Each customer spends an average of 85 seconds completing his or her transactions. Transaction time is exponentially distributed. a. Determine the average time customers spend at the machine, Including waiting in line and completing transactions. (Do not round Intermediate calculations. Round your answer to the nearest whole number.) Average time |minutes b. Determine the probability that a customer will not have to wait upon arriving at the automatic teller machine. (Round your answer to 2 decimal places.) Probability c. Determine the average number of customers waiting to use the machine. (Round your answer to 2 decimal places.)

Assuming an 8 hour work-day, the watchmaker averages 3 customers arriving at his shop every day following a poisson distribution. The watchmaker just purchased a new machine that will polish the dial and crystal reducing his service time by 20 minutes per watch. How much will the line for a watch waiting to be serviced be reduced by the watchmaker using this new machine, assuming no increase in customer demand? O 2.25 watches waiting for service O The number waiting to be serviced will be reduced by about 1.2 watches O The number waiting to be serviced will be reduced by about 0.4 watches The number waiting to be serviced will be reduced by about 1.45 watchesarrow_forwardTrucks arrive at the loading dock of a wholesale grocer at the rate of 1.2 per hour. A single crewconsisting of two workers can load a truck in about 30 minutes. Crew members receive $10 perhour in wages and fringe benefits, and trucks and drivers reflect an hourly cost of $60. The manager is thinking of adding another member to the crew. The service rate would then be 2.4 trucksper hour. Assume rates are Poisson.a. Would the third crew member be economical?b. Would a fourth member be justifiable if the resulting service capacity were 2.6 trucks per hour?arrow_forward

- Consider a bank where potential customers arrive at rate of 60 customers per hour. However, because of limited space, one out of every four arriving customers finds the bank full and leaves immediately (without enteringthe bank). Suppose that the average number of customers waiting in line in the bank is 3.5. How long will a typical entering customer have to wait in line?

The time between requests can be modeled by a negative exponential distribution. Customers arrive at a rate of 12 per hour. A clerk can handle requests at a rate of 10 per hour, and this can be modeled by a Poisson distribution Clerks cost $25 per hour and mechanics cost $25 per hour. Use Table 18-4. a.
