We have learned that this waiting time model is only valid if the utilization is less than 100% (this means, on average, there is enough time to serve all customers). What happens to the waiting time if the utilization is greater than 100%?

Answer #1

If the utilisation is greater than 100% which means that the current system is over utilised and need more system/resources to meet the demand . Over 100% the waiting time will be directly proportional to the number of new entries or customers in the queue which can be optimised only through reducing the turn around time through operational efficiency and capabilities. Over utilised system will even results in infinite waiting period when the queue strength is going beyond the proprotional rate. Above 100% systems are more tend to be inefficient because of their lack of capability in meeting with the required actual demand.

The bank manager wants to show that the new system reduces typical customer waiting times to less than 6 minutes. One way to do this is to demonstrate that the mean of the population of all customer waiting times is less than 6. Letting this mean be µ, in this exercise we wish to investigate whether the sample of 93 waiting times provides evidence to support the claim that µ is less than 6.       For the sake of argument, we...

*please use excel and provide the formulas Customers arrive randomly at a product returns counter at a department store, which meets the assumptions of the Single-Server, Single-Phase waiting line model (i.e., the arrival rate is Poisson distributed and service rate is exponentially distributed). There is only one returns employee, and the time required for returns varies from customer to customer. There is a single waiting line. The average arrival rate is 15 customers per hour. The average time to serve...

The population mean waiting time to check out of a supermarket has historically been 4 minutes. In an effort to reduce the waiting time, you, as store manager, conducted an experiment with infrared cameras that use body heat and in-store software to determine how many lanes should be opened. To test the effectiveness of this process, you selected a random sample of 100 customers and recorded their waiting time. For this sample, the mean waiting time to check out was...
