True (T) or False (F) Questions In a queuing system, if the system’s utilization is 100%, then the customer waiting time will be zero. In an EOQ model, if the unit inventory holding cost doubles, the optimal order quantity should be cut to half. Assignable causes of variation are those that are frequent, random, and whose source cannot be identified.
