We study a staffing optimization problem in multi-skill call centers. The objective is to minimize the total cost of agents under some quality of service (Q...

In time-to-event data analysis, the main object of interest is the time elapsed between the occurrence of two ordered events, say E1,E2. Sampling fr...
