In this paper, we consider a single-server queuing system whose service quality is either high or low. The server, who knows the actual quality level, can signal such quality information to customers via revealing or concealing his queue length. Based on this and the observed queue length in the...

Consider a single-server service system with uncertain quality level (which is assumed to be binary). Both the server and the customers know the distribution of quality levels and are engaged in the following two-stage game. In the first stage, the server commits to a strategy (possibly mixed)...

We study a two-stage decision problem, namely, the allocation and deployment of reserved inventories (RIs) in a supply network with random demand surges. The demand surge follows a time-dependent stochastic process and our objective is to minimize the expected total unmet demand in the presence...

In this paper, we study customer equilibrium as well as socially optimal strategies to join a queue with only partial information on the service time distribution such as moments and the range. Based on such partial information, customers adopt the entropy-maximization principle to obtain the...

We consider a three-tier supply chain consisting of an original equipment manufacturer (OEM), a contract manufacturer (CM) and a supplier. We analyze and compare three outsourcing structures that are currently implemented by top-tier OEMs: (1) inhouse consignment, under which the OEM signs...
