报告摘要：In this talk, we consider a fluid queue with working vacations. Once the buffer becomes empty during the normal busy period, the system will enter a working vacation period during which the outflow rate of fluid will be switched to a lower rate than that in normal busy period. After this working vacation period, if the buffer is non-empty, the outflow rate will be switched to normal rate immediately, otherwise, the system will enter another working vacation until the buffer is non-empty after one working vacation and a new normal busy period starts. For such fluid queue, based on the utility function, we analyze the strategic behavior of the customers, regarding the joining/balking dilemma, under the fully observable case and almost observable case. Furthermore, the expected social benefits are obtained, the corresponding optimal social benefits are also studied and the inefficiency of the equilibrium strategies is quantified via the Price of Anarchy (PoA) measure.
