There are much collaboration and cooperation in the dynamic, multi-institutional virtual grid. Grid provides a good bridge between the resource users and the resource providers. Especially in the agent-based grid system, agents could provide services for the scheduling of applications that make grid resources better use. We have proposed a resource discovery mechanism with negotiation in grid environment...
In this paper, the author uses the Rockwell Arena simulation software to simulate two kinds of Congestion of visitors moving of Shanghai Expo2010. The results indicates that the congestion of entrance check-in of Expo park can be controlled in advance, about 200 ticket punches may cater to the requirement. Another problem is considered to be the congestion of popular venues in the park. Even assuming...
This paper investigates the retailer's optimal inventory policy under supplier credits including cash discount and partially or fully permissible delay in payments depending on retailer's payment time. One theorem is developed to efficiently determine the optimal replenishment and payment policy for the retailer. Finally numerical examples are shown to illustrate the results in the paper.
Usually it is assumed that the supplier would offer a fixed credit period to the retailer but the retailer in turn would not offer any credit period to its customers, which is unrealistic, because in real practice retailer might offer a credit period to its customers in order to stimulate his own demand. Moreover, much of existing EOQ models under a given delay-in-payments tactic consider to decide...
In this paper, we propose to tackle the joint dynamic routing and admission control (JRAC) problem for the IP traffic flows in MPLS networks without rerouting the already admitted flows. Two mathematical programming models are proposed for this problem.The numerical results have demonstrated that the proposed approach can offer less flow blocking rate and reduce significantly the mean end-to-end delay...
We investigate competition between network providers that offer service to two types of traffic differing in their sensitivity to delay. We first consider competition amongst network providers who offer differentiated services by providing a priority queue for the delay sensitive traffic. We compare this to a situation in which all the competing network providers have network architectures that treat...
With the development of high rate data transmission technology via distribution line communication, the electric power, data, voice and video can be transferred in the same electric power distribution network, and the technology will be put in operation widely in the future. However the traditional technology of power line communication is not adaptable to the complex and harsh environment of distribution...
Alternating-Offer Protocol (AOP) is the most predominant way for one-to-one bargaining. Almost all past theoretical or practical researches on bargaining issue adopt AOP as the default trading rule. In this paper, we provide an alternative protocol, Sealed-Offer Synchronous Bargaining Protocol (SOSBP), which can be useful for the automated bargaining between self-interested agents for Open E-Marketplaces...
Design of controllers for decentralised have been considered by many researchers who have assumed that implementation of these controllers would not provide any additional problems. In this paper a number of different implementation configurations are considered. It is shown that different closed-loop dynamics may result, based on sampling rates, connection topologies and communication traffic. An...
A discrete-event system G is modelled as the controlled generator of a formal language L(G), in the framework of Ramadge and Wonham. By means of the concepts of well-posed language and well-posed supervisor, it is suggested how this framework can accommodate certain real-time control constraints. Then it is shown that a closed-loop supervisory control has `correct' real-time behavior if and only if...
