Consider a call center for software support:
- 3 representatives answer phones (each can handle all types of calls)
- Calls arrive according to a Poisson process. On average, there are 20 calls per hour, 50% high priority, 50% low priority
- The service time for each call follows an exponential distribution. On average, it takes 4 minutes to answer each call.
