Arena simulation

What you want to solve (indicate the decisions that you want to make) and what outcome you expect. According to the problem, define the objective(s) and constraints if any. The objectives could be, but not limited to, 1) minimizing the total cost, 2) maximizing the profit, or 3) maximizing the utilization of resources. The constraints could be, but not limited to, 1) waiting time less than a threshold, 2) the total number of resources less than a predetermined number, and/or 3) the total time in system less than a threshold. The decisions could be, but not limited to, 1) number of resources; 2) staffing schedule; 3) queueing disciplines; 4) new layout design; 5) new process; and 6) new technologies
