A manager must determine requirements for waiting space for customers. A priority system is used to process customers, who are assigned to one of two classes when they enter the processing center. The highest-priority class has an arrival rate of four per hour, the other class has an arrival rate of two per hour. Both can be described as Poisson-distributed. There are two servers, and each can process customers in 15 minutes, on average. Use Table 18.4. a. What is the system utilization? (Round your answer to 2 decimal places.) 0.53 b. Determine the number of customers of each class that are waiting for service. (Round your answers to 3 decimal places.) Ly L A manager must determine requirements for waiting space for customers.
