G-networks are novel product form queuing networks that, in addition to ordinary customers, contain unusual entities such as “negative customers” which eliminate normal customers, and “triggers” that move other customers from some queue to another. Recently we introduced one more special...

Consideration is given to the queueing system with incoming Poisson flows of regular and negative customers. Regular customers await service in buffer of finite size r. Each negative customer upon arrival pushes a regular customer out of the queue in buffer (if it is not empty) and moves it to...

In this paper we survey work related to queues with interruptions that occur due to many reasons such as server breakdowns, servers taking emergency breaks, and customers having incomplete information or getting distracted. We look at both continuous and discrete time queueing models with...

Customer lifetime value (CLV) is an established relationship marketing-centric approach to evaluating performance: based upon the significance of a customer, and what resources should be allocated towards maintaining relations - beyond short-term transactional views. The conceptual argument...

In recent years the United States has actively begun to engage in the negotiation of bilateral and regional trade agreements, a significant change from its long-standing commitment to the exclusive use of multilateral institutions for trade liberalization. While the "unequal economic power"...

A monopolist deliberately charges the same price for differentiated products when high quality products are more likely to be allocated to low type consumers under uniform pricing. The argument can explain the use of ‘unpriced quality’ for concert tickets, sport events, and in many other...

Metro station corridor width design considering demand fluctuation as well as the randomness and state-dependence of service time is an urgent concern and a complicated random planning issue. This paper confirms the accuracy of phase-type distribution (PH) fitting for passenger arrival intervals...

We study how net neutrality regulations affect a high-bandwidth content provider's (CP) investment incentives in quality of services (QoS). We find that the effects crucially depend on network capacity levels. With limited capacity, as in mobile networks, prioritized delivery services are...
