Abstract Congestion externalities are a well-known phenomenon in transportation and communication networks, healthcare etc. Optimization by self-interested agents such settings typically results equilibria which sub-optimal for social welfare. Pigouvian taxes or tolls, impose user charge equal to the negative externality caused marginal other users, mechanism combating this problem. In paper, w...

Markov model of multi-component machining system comprising two unreliable heterogeneous servers and mixed type of standby support has been studied. The repair job of broken down machines is done on the basis of bi-level threshold policy for the activation of the servers. The server returns back to render repair job when the pre-specified workload of failed machines is build up. The first (seco...

An important technique for saving energy in data centers is consolidating work onto a small number of well utilized servers via dynamic capacity provisioning. A common approach for dynamic capacity provisioning is “receding horizon control” (RHC), which computes the provisioning for the current time by optimizing over a given window of predictions about the future arrivals. In this work, we pro...

We study a tandem queueing system with K servers and no waiting space in between. A customer needs service from one server but can leave the system only if all down-stream servers are unoccupied. Such a system is often observed in toll collection during rush hours in transportation networks, and we call it a tollbooth tandem queue. We apply matrix-analytic methods to study this queueing system,...

In the current internet scenario more virtual servers and mirror servers are utilized to maintain load balance of the heterogeneous peer to peer networks. One of the most current existing works developed a state balancing system based on probability distribution of peer abilities, loads of virtual servers, and incomplete data of global peers. On the other hand state balancing method recognizing...
