This paper presented an accounting and charging system based open grid services architecture (OGSA), which developed with an emphasis on a consistent data model and easy integration into existing scheduling at a few independent resources providers to use under various grid environment. This accounting and charging system mainly addresses to resolve the problem of accounting and charging of resources...
Construction project bidding is a kind of transaction way of construction project the most widely used ,the bidding is a closed price auction, the game among the bidders and the tenders belongs to a kind of non-cooperation and incomplete static game and so does it among the tenders. According to the special rules of bidding, the game theory is put into construction project bidding ,the game model...
In this paper, we propose a set of semantic cohesion metrics for ontology measurement, which can be used to assess the quality of evolving ontologies in the context of dynamic and changing Web. We argue that these metrics are stable and can be used to measure ontology semantics rather than ontology structures. Measuring ontology quality with semantic inconsistencies caused by ontology evolutions,...
Section theorem has become an important role in social economy and mathematics field. The solutions of several problems, for example, optimization problem, fixed point problem, non-cooperative game problem, complementarity problem, and variational inequality problem, can be formulated as special cases of section theorem. So it is necessary to study section problem. In the setting of topological ordered...
In this paper we consider the mechanism design of traffic BOT project auction. We set up the model of traffic BOT project auction where firms bid on capacity and concession term, and bids are evaluated by a scoring rule designed by the auctioneer. We educe the optimal auction mechanism by analyzing the incentive compatibility. In addition, we find that the optimal capacity is chosen independently...
The programming languages solution to local-area networks is defined not only by the improvement of neural networks, but also by the technical need for Web services. Based on the game-theoretic symmetries, the Smalltalk harnessing are introduced, applied and researched. In fact, though few experts would disagree with the synthesis of operating systems, the Smalltalk harnessing is useful and applicable...
This paper applies the multi-agent system Strategy to collaborative negotiation in manufacturing supply chain coordination. Multi-agent computational environments are suitable for studying a broad class of coordination and negotiation issues involving multiple autonomous or semiautonomous problem solving agents.
Construction enterprises win the project by construction project bidding .In present system of biding ,the threshold bidding cost directly impacts on bidding for quotation price of winning the tender, so it is very critical to design reasonable cost threshold in completive-bidding .There are many factors that influence the construction cost, which make construction cost to have the character of the...
Put forward a new information retrieval method based on the query specificity after analyzing the existing problems of information retrieval system. The experiments show that the system has better query performance. Avoid the similarity documents in the first few pages effectively, when the system return a larger set of query documents.
In this paper, a novel fuzzy particle swarm optimization (NFPSO), in which inertia weight as well as the learning coefficient can be adaptively adjusted according to the control information translated from the fuzzy logic controller (FLC) during the search process, is presented by introducing a two-input and two-output FLC into the canonical particle swarm optimization (CPSO). The effectiveness of...
Firstly, we give the definition of an L-bifuzzy Scott closed subset and prove its related properties, then, we give the definition of an L-bifuzzy Scott co-topological space, study its properties and equivalently characterize it which is a generalization of the Scott co-topological space in the classical topology theory. Finally, we establish the relationships of L-bifuzzy domain, L-bifuzzy lower...
A new method is emerging in the field of high-rise building in recent years. That is water supply of non-negative pressure. For the reasons of used quantity of water cannot be predicted and non-equilibrium and other reasons, the water pressure is changed notable, it cannot meet the requirements of users by water pressure. The digital PID control is the common control method in the process of manufacture...
In this paper, a filled function approach for constrained global optimization (FFACGO) is proposed. It is a combination of the idea of filled function method in unconstrained global optimization with the concept of penalty function in constrained optimization. Moreover, this FFACGO can be easily actualized with a process that aims at successively finding better optimizer. The performance of the FFACGO...
Mining frequent patterns plays an important role in mining association rules, correlation, multi-dimensional patterns, etc. Since any nonempty subset of a maximal frequent itemsets also is frequent, it is sufficient to mine only the set of maximal frequent itemsets. In this paper, we still base on the FP-tree and propose an optimized algorithm to mine maximal frequent itemsets. By analyzing the data...
The exterior of Environmental resources decide that the Energy consumption and reducing pollutant emissions can restrict and improve the way of Production and life by means of energy and environmental control policy. Because the existing environmental policy can not restrain the over-consumption of energy and deteriorating environmental situation phenomenon fundamentally, we establish a BP neural...
It is recognized within data fusion domain that the main challenge in devising gradient order fusion algorithm is to provide a feasible architecture in fusion system, which will comprise concerned entities in diverse subject-specific fusion model, besides, the characteristics, fusion situations and interrelations among system components have been demonstrated the key factors in the decomposition in...
This paper proposes a cooperation mechanism among seller agents and builds a model based on multi-agent system. In the model, a manger agent has been set to watch activities of other agents. It will encourage the cooperative sellers and punish the non-cooperative seller agents by adjust the sellerpsilas reputation in the repository. With this mechanism, a seller would complete the trade with the buyer...
Virtual learning community give students more free and open environment for studying on the Internet. This research is based on constructive learning theory and virtual learning community, from design and speciality of virtual learning community, and the ways of browsing.
When Blog comes to the world, how to use Blog in education and instructions well has been one of the interesting studies among academic field increasingly. In this paper, by reading great material and communicating with the teachers in Rizhao open-up areal, it discussed the applications of Blog in education and teaching from sharing resources and communication of teachers, students and studentspsila...
