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. Question 10 options:  Stationarity   Stability   Sustainability   Seasonality  Engineering & TechnologyIndustrial EngineeringOperations ManagementMGNT 371Share Question
