Block appointment systems for outpatient clinics with multiple doctors

Studies of appointment systems have to some extent led to a wide acceptance of individual or block appointment schemes in private practice and outpatient clinics. Most of the studies assume there is one punctual doctor in a clinic, which is often not the case in reality. Motivated by observations of actual clinic operations, we develop a block appointment system for clinic operations with multiple random arriving doctors. Through extensive simulation studies, we identify properties shared by the best appointment schedules. With these properties we can design a scheme based on simulation search that provides the optimal schedule for a given scheduling environment in an acceptable computation time. A simple (suboptimal) appointment rule is also proposed.
