Abstract:
Driven by the need to develop methods for minimizing operational delays at public administration agencies,
this paper considers problems involving routing and staffing in these agencies. We examine a threshold-based
N-System of two queues with capacities C1 = ∞ and C2 < ∞, respectively. We use the matrix analytic method
to obtain the steady-state probabilities, the performance measures, and the optimal threshold values in terms
of the system parameters. Our numerical experiments reveal that the mean response time is sensitive to the
stability condition, and the effectiveness of the threshold policy depends on the customer arrival rate.
