question number 19For many waiting line situations, the arrivals occur randomly and independently of other arrivals and it has been found that a good description of the arrival pattern is provided bya normal probability distribution. an exponential probability distribution. a uniform probability distribution. a Poisson probability distributionQuestion 16 1 points Save The manner in which units receive their service, such as FCFS, is the queue discipline. channel. Question 15 1 points Save The total cost for a waiting line does NOT specifically depend on the cost of waiting. the cost of service. the number of units in the system. the cost of a lost customer. steady state. operating characteristicQuestion 11 1 points Save Decision makers in queuing situations attempt to balance operating characteristics against the arrival rate. service levels against service cost. the number of units in the system against the time in the system. the service rate against the arrival rate.
