Question: Consider a B&D queuing system which has a finite number of states denoted by n = 0, 1, 2, 3, 4. The arrival rates are

Consider a B&D queuing system which has a finite number of states denoted by n = 0, 1, 2, 3, 4. The arrival rates are = 4 for = 0, 1, 2, 3. The service rates are = for = 1, 2, 3, 4. 1. Give an example of a queuing system which can be described by these arrival and service rates. 2. Calculate the steady-state probabilities {Pn} of the system states using the general approach discussed in class, as well as in the textbook. Next, determine the expected queue length, the expected arrival rate, and the expected waiting time. 3.Consider this queuing system in its steady-state condition. We assume that if the system is in state n, then the system cost per day, expressed in thousands of dollars, is f() = 2. Determine the expected system cost per day.
