In recent years there has been increasing focus on the behavioral aspect in many disciplines, queuing being one of them. There are various methodologies that enable incorporation of behavioral issues in queuing models. The choice of method will be driven by the emphasis of the study (repeat customers, information diffusion, reputation buildingand so on) and the level at which these phenomena are being studied. In this chapter we compare two approaches to studying behavioral queuing problems-agent based modeling and experimental methods-and address the complementarity of these methods. For instance the experimental method can be used to validate insights derived from agent based models.
