Scenario E.1 SimQuick is being used to simulate the following bank process: Entrance Door Buffer Line Work Station Teller Buffer Served Customers Customer arrivals at the Entrance Door of the bank with an average time between arrivals of 2.5 minutes. The Line Buffer holds 6 customers. If a customer arrives and the buffer line is filled, the customer leaves. The Work Station Teller's processing time per customer is normally distributed, with a mean of 3.0 minutes and a standard deviation of 0.5 minutes. The Served Customer Buffer in the flow chart is used to count the number of customers processed during the period simulated. A 2-hour period was simulated. The SimQuick simulation is run, and the results are as follows: Overall Element Types Element Names Statistics Means Entrance Door Objects entering process 41.80 Objects unable to enter 6.23 Service level 0.87 Buffer Line Objects leaving 37.83 Final inventory 3.98 Minimum inventory 0.00 Maximum inventory 5.85 Mean inventory 3.08 Mean…

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?

Please do not give solution in image format thanku The flow rate through a process is 0.5 flow units per minute. The number waiting for the process is 1. The time to do the activity in the process is 1 minute. This is a stable system. The average amount of time a flow unit spends waiting for the activity and doing the activity = ______. Enter one integer (which can be 0) and ONE decimal, so the answer looks like X.X. Any of the Xs can be a 0.

55. The mail order firm of L. L. Pea receives an averageof 200 calls per hour, where times between calls areexponentially distributed. It takes an L. L. Pea operatoran average of three minutes to handle a call. If a callergets a busy signal, L. L. Pea assumes that he or she willcall a competing mail-order company, and L. L. Pea willlose an average of $30 in profit. The cost of keeping aphone line open is $9 per hour. How many operatorsshould L. L. Pea have on duty? Use simulation to answerthis question. Does the answer depend on whether theservice times are exponentially distributed?

Navern Corporation manufactures and sells custom home elevators. From the time an order is placed until the time the elevator is installed in the customer's home averages 141 days.

A machine is set to pump cleanser into a process at the rate of 5 gallons per minute. Upon inspection, it is learned that the machine actually pumps cleanser at a rate described by the uniform distribution over the interval 5.0 to 8.0 gallons per minute. Would you expect the machine to pump more than 7.85 gallons per minute?

It takes a service rep an average of 1.5 minutes to take a customer's information. Over the course of a workday, the rep handles 150 calls a day during her eight-hour shift. The service rep's utilization (in %) is %. (Enter your response rounded to one decimal place)

Agan Interior Design provides home and office decorating assistance to its customers. In normal operation, an average of 2.6 customers arrive each hour. One design consultant is available to answer customer questions and make product recommendations. The consultant averages 10 minutes with each customer. (a) Compute the operating characteristics of the customer waiting line, assuming Poisson arrivals and exponential service times. (Round your answers to four decimal places. Report time in hours.) ?=?=Lq=L=Wq= hW= hPw= (b) Service goals dictate that an arriving customer should not wait for service more than an average of 5 minutes. Is this goal being met? (Round your answer to one decimal place.) Wq (in minutes) =  min, which is     than the desired wait time, so the goal     met. What action do you recommend? (Select all that apply.)
