QuestionAnswered step-by-stepWhich of the following is a source of variability in a queue?…Which of the following is a source of variability in a queue? Question 1 options: Variability of the processing times Variability of the inflow of units Random availability of resources Random routing of multiple flow units These are all sources of variability Question 2 (1 point) The coefficient of variation is a _________ measure of variability. Question 2 options: Demand-constrained Relative Absolute Precise Question 3 (1 point) When a customer switches from one line to a different line, this is an example of _________. Question 3 options: Balking Reneging Self-serving Jockeying Question 4 (1 point) Which statement is true? Question 4 options: As utilization increases, time in queue increases As utilization increases, time in queue decreases As utilization increases, time in queue stays the same Question 5 (1 point) In the article “The Psychology of Waiting Lines”, the author states that Satisfaction = _____ – Expectations. Question 5 options: Perfection Preparation Perception Productivity Question 6 (1 point) Which of the following is NOT a rule identified in the article, “The Psychology of Waiting Lines”? Question 6 options: Group waits feel longer than solo waits Uncertain waits are longer than known, finite waits Unfair waits are longer than equitable waits The more valuable the service, the longer the customer will wait. Question 7 (1 point) The practice of using multiple servers is known as ________. Question 7 options: Poisson processing Pooling Appointment systems Batch processing Question 8 (1 point) The first customer arrives at 8:06 am. The second customer arrives at 8:15 am. What is the interarrival time? Question 8 options: 9 minutes 15 minutes 10.5 minutes 21 minutes Question 9 (1 point) What is NOT true about the exponential distribution? Question 9 options: Arrivals occur at equal intervals of time, for example, one arrival exactly every 5 minutes. It exhibits the memoryless property If the interarrival times are exponentially distributed, then the arrivals follow a Poisson process The coefficient of variation of an exponential distribution is equal to 1 Question 10 (1 point) Unlike variability, ___________ can be predicted ex ante.
