Question: Consider a three-node network around which customers must travel cycllcally. The service time at node I is exponentially distributed with mean mi, i = 1,2,3.

Consider a three-node network around which customers must travel cycllcally. The service time at node I is exponentially distributed with mean mi, i = 1,2,3. If there is only one customer in the system, set up the balance equations to calculate the fraction of time the customer spends at each node, and solve them.
