or

Double

b. In queuing theory, the long-run average number of customers in a system is designated by L. For a specific type of single-server system with arrival rate denoted by Lambda and service rate denoted by , L = Lambda/-Lambda. Consider such a system in which the arrival rate Lambda = 10 per hour and the service rate = 30 per hour. If the arrival rate doubles to 20 per hour, then L will:

Increase by a factor of four

or

remain unchanged

c. In the process of an economic order quantity (EOQ) inventory analysis, if the holding cost for an item doubles and all other parameters remain unchanged, the order quantity will decrease, and the reorder point will remain unchanged. True or False
