  • Priority Service and max-min fairness
    IEEE ACM Transactions on Networking, 2003
    Co-Authors: Peter Marbach
    Abstract:

    We study a Priority Service where users are free to choose the Priority of their traffic, but are charged accordingly by the network. We assume that each user chooses priorities to maximize its own net benefit, and model the resulting interaction among users as a noncooperative game. We show that there exists an unique equilibrium for this game and that in equilibrium the bandwidth allocation is weighted max-min fair.

  • INFOCOM - Priority Service and max-min fairness
    Proceedings.Twenty-First Annual Joint Conference of the IEEE Computer and Communications Societies, 2002
    Co-Authors: Peter Marbach
    Abstract:

    We study a pricing scheme for networks which use priorities to provide differentiated quality of Service. We consider the situation where users are free to choose the Priority of their traffic, but are charged accordingly. We model this situation as a non-cooperative game, where users behave in a selfish manner and choose an allocation of priorities to packets to optimize their own net benefit. We show that there exists an unique equilibrium for this game and the bandwidth allocation in equilibrium is weighted max-min fair.

  • pricing differentiated Services networks bursty traffic
    International Conference on Computer Communications, 2001
    Co-Authors: Peter Marbach
    Abstract:

    We study the role of pricing in differentiated Services (Diff-Serv) networks. We model DiffServ as a Priority Service, where users are given the freedom to choose the priorities of their traffic, but are charged accordingly. Using a game theoretic framework, we study the case where users choose an allocation of priorities to packets in order to optimize their net benefit. For the case where users with bursty traffic access a single link, we show that there always exists an equilibrium for the corresponding noncooperative game. Furthermore we show that pricing can be used to provide relative QoS guarantees.

  • Simulation Modelling of Ship-Berth Link With Priority Service
    Maritime Economics & Logistics, 2005
    Co-Authors: Branislav Dragović, Nam Kyu Park, Zoran Radmilović, Vladislav Maraš
    Abstract:

    Simulation of the logistics activities related to the arrival, berthing, Service and departure processes of ships in container ports can be carried out for different goals such as design of ship-berth link, increase productivity and efficiency of quay cranes, analysis and planning of operations at the ship-berth link, etc. These logistics activities are particularly complex and very costly since they require the combined use of expensive infrastructure capacities especially berths and quay cranes. Ship-berth link as a main port link is required to serve ships as quickly as possible. Thus, in order to successfully design and develop ship-berth link in a container port and utilise it as efficiently as possible, it is necessary to develop a simulation model that will support decision-making processes of terminal managers. The results, analysis and conclusions given in this paper are intended to provide guidance on achieving time efficiency and accuracy in the modelling of ship-berth link and calibration of ship-berth link simulation models for Pusan East Container Terminal (PECT).

  • a historical perspective and business model for load response aggregation based on Priority Service
    Hawaii International Conference on System Sciences, 2013
    Co-Authors: Shmuel S Oren
    Abstract:

    We review early technologies and experiments in the 1980's for implementing demand response. We argue that while new smart grid technologies are cheaper and provide more functionality the barrier to demand response implementation at the retail level lies in the development of business models that will incentivize customer participation on the retail side and facilitate integration of the aggregate responses into the wholesale market. We then describe such a model that is based on the concept of Priority Service where customer can choose different levels of interruption for segments of their loads which they can reallocate at will within the household. We review the theory of efficient pricing of such Service along with alternative implementation forms. We then illustrate by means of an example the potential economic gains of such an approach.

  • Privatizing electric reliability through smart grid technologies and Priority Service contracts
    IEEE PES General Meeting, 2010
    Co-Authors: Shmuel S Oren
    Abstract:

    Smart grid technologies in combination with the methodological foundation laid by the economic theory of Priority Service, enable the conversion of electric Service reliability from a public good to a private good. Such a transformation is achieved by offering electricity Service as a product line differentiated according to Service reliability from which customers can self-select the level of reliability that fits their needs and pocketbook. This conceptual paradigm is illustrated through a specific proposal for a multilevel Emergency Interruptable Load Response Service (EILS) program at ERCOT.

  • waiting time analysis of the multiple Priority dual queue with a preemptive Priority Service discipline
    European Journal of Operational Research, 2006
    Co-Authors: Panlop Zeephongsekul, Anthony Bedford
    Abstract:

    The dual queue consists of two queues, called the primary queue and the secondary queue. There is a single server in the primary queue but the secondary queue has no Service facility and only serves as a holding queue for the overloaded primary queue. The dual queue has the additional feature of a Priority scheme to help reduce congestion. Two classes of customers, class 1 and 2, arrive to the dual queue as two independent Poisson processes and the single server in the primary queue dispenses an exponentially distributed Service time at the rate which is dependent on the customer's class. The Service discipline is preemptive Priority with Priority given to class 1 over class 2 customers. In this paper, we use matrix-analytic method to construct the infinitesimal generator of the system and also to provide a detailed analysis of the expected waiting time of each class of customers in both queues.

  • on a dual queueing system with preemptive Priority Service discipline
    European Journal of Operational Research, 2005
    Co-Authors: Anthony Bedford, Panlop Zeephongsekul
    Abstract:

    In this paper, we use matrix-analytic methods to construct a novel queueing model called the dual queue. The dual queue has the additional feature of a Priority scheme to assist in congestion control. Detailed structure of the infinitesimal generator matrix is derived and used in the solution process. Using a computational algorithm, which utilises a combination of iterative and elementary matrix techniques, the steady state solution is obtained for all queues with a finite buffer. Finally, we present numerical examples to illustrate the algorithm.

  • Subsidy free pricing of interruptible Service contracts
    Energy Economics, 1995
    Co-Authors: T. Randolph Beard, George H. Sweeney, Daniel M. Gropper
    Abstract:

    Abstract This article analyzes the issue of cross-subsidy in the pricing structure of a utility offering interruptible Service contracts. Utilizing a simple theoretical model in which available capacity is subject to random shocks, we derive a set of sufficient conditions for the presence of subsidies in the pricing of Priority Service. We find that low Priority customers receive no subsidies whenever they pay prices in excess of variable costs. A test for subsidies to high Priority customers is derived that can be implemented utilizing available information. Extensions of the analysis are discussed.
