We consider the appointmentscheduling problem, which determines the job allowancefor each customer over the planning horizon. In particular, we study a simpleyet effective scheduling policy--the so-called “plateau policy”, whichallocates a constant job allowance for each customer. Prior studies onappointment scheduling suggest a “dome shape” structure for the optimal joballowance, which implies that job allowance does not vary significantly in themiddle of the schedule, but varies at the beginning as well as the end of theschedule. Using a dynamic programming formulation, we derive an explicitperformance gap between the plateau policy and the optimal schedule, andexamine how this gap behaves as the number of appointments increases. We showthat the “plateau policy” is asymptotically optimal with respect to the numberof appointments. We further extend this result to a more general setting withmultiple service types. Numerical experiments show that the “plateau policy” isnear optimal even for a small number of appointments, complementing thetheoretical results we derived. Our result provides a justification and supportfor the “plateau policy”, a commonly used appointment policy in practices.
