Because of the heterogeneity of Internet (both of the software and hardware), the education resources cannot be shared sufficiently, and lots of them are redeveloped. The foundation of value-added service system of educational resource is metadata, resource finding mechanism, resource collecting and reproduced and publishing mechanism.
In order to provide high quality of service (QoS), reasonable scheduling and resource allocation are needed when a great deal of tasks request grid resources. By quantifying some important properties of Grid QoS and maximizing cost-performance of the system, a grid resource selection optimization algorithm is provided based on simulated annealing genetic algorithm (SAGA) : QoS-aware SAGA, and the...
The paper, combining the basic principle and architecture of grid technology as well the combined application in grid fault diagnosis expert system, puts forward the application scheme of EJB component in grid fault diagnosis system. The paper designs the grid service layer based on OGSA, and discusses the application methods of grid for fault diagnosis expert system. The fault diagnosis grid framework...
In our previous works, based on characteristics of emergency systems such as quick response to emergencies, a polynomial time algorithm was proposed to solve task schedulable problem. However, the above mentioned task scheduling method did not consider importance and urgency differences among tasks in selecting task to accomplish. In order to make the task scheduling be more close to actual process...
As a social entity, agent needs to collaborate with others to execute a task in most multi-agent systems. Agent has its own intention and interest as an individual, which is ignored in most systems and has great influence on cooperating with other agents. In this paper, referring to the principle of interest group in real life, a multi-agent cooperation scheme based on interest group to solve the...
Recent success deployment of P2P streaming can provided hundreds of media channels of users at any given time. This evokes an interesting question can the streaming server allocate channel resources efficiently with limited capabilities? In this paper, we propose an auction-based new strategy for resources allocation. The mechanism enable streaming server can provide service according to peer's bidding...
In view of the lack of high-quality system development, this paper proposes the "intelligent platform for MIS" concept from the reuse and specification aspects so that system developers can use "natural" coding technology to develop platform-based program in a real sense. It can't only make system development easier, but also improve the maintainability.
It is difficult for incomplete contract theory (ICT) to modeling under the consumption of bounded rationality. After the GHM model, the challenge for its robust foundation hasn't stopped. Besides, the robustness becomes perfect after the disputes between MT and HMS. Theirs debate is focus on theory's foundation. This paper formalizes the disputes in an integrated framework and comments on the constraint...
Chiefly aimed at the distributed resource search status in the present educational field, this paper brought the conception of individuation search based on the consumers' interest. The relevant models of individuation analysis and individuation resource searching were designed in this paper. At the same time, self-study arithmetic, the method of information searching and information filtering, was...
Coordination decision is the important problem of e-government currently. Multi-agent is a problem solving networks by the formation of collaborative among many agents. It can enhance the capacity of the entire system through the task decomposition and task coordination. Mobile-agent, is a software that can autonomous migrate from one host to another host in heterogeneous network, and have interactive...
The allocation of emergency resources is an important part of emergency decision. In this article, a dynamic programming model and goal programming model of emergency resources were presented. At the same time, aiming at solving the faultiness and inflexibility, the article presents a method of making multi-stage emergency decisions based on the theory of risk analysis and repast symphony platform...
Based on analysis of various P2P architectures, the authors in this paper integrate semantic grid with super-peer P2P architecture. First of all, the authors introduce resources searching algorithm based on semantic cluster, and analyze the educational resources sharing mechanism & service system based on super-peer P2P, especially on the model of super-peer P2P. Then the authors focus on the...
This paper describes how to dynamically form a Task-oriented organization using a concept of complex networks, which we use to define the entities and relationships of a typical organization in the domain of combat simulation. First, we analyze and describe network characteristics of real combat organization. Second, we present a dynamic network organization formation method, including task decomposition...
The supply chain system consists of one supplier and one retailer. When demand function and cost were disrupted simultaneously, how the disruptions effect the supply chain was discussed, and the disruption management decisions of individuals were analyzed. The optimal strategies that supply chain replied to the disruptions were proposed, and an improved revenue sharing contract was presented under...
This paper proposes a method for adaptive bit loading under the CSI gotten by the channel estimation based on the comb-pilot frequency insertion. The sub-carriers are divided into a few groups and the CSI based on the channel estimations are got by comb-pilot frequency to track the time-varying channel. It implements the bit loading algorithm. Sub-channel allocation and bit loading are separated under...
Aviation project which always involves too many resources need to do resource leveling for enhancing the utilization of resources so as to reducing project cost. Intelligent optimization algorithms and heuristic approaches are inefficient and inflexible when solving large-scale aviation resource leveling problems. A hybrid algorithm based on Artificial Immune Algorithm (AIA) and Ant Colony Optimization...
This article analyzed the development of cultivation mode of professional degrees (PD) based on system thinking. The system of the development of cultivation mode of PD can be divided into three subsystems: the program developing system, the faculty developing system and the management improving system. By building the causal loop diagrams, this article demonstrated the impact between the variables...
The existing automated testing frameworks are designed and implemented on demand of particular test requirement or test types, so have to build different types of automated testing framework to meet the requirement of different types of testing, the construction cost of automated testing framework is very high. In this paper, agent-based distributed automated testing executing framework is presented...
This article is absorbed in the grid and a system framework for the simulation grid is introduced. The model of the modularization function is designed. The solution of pivotal technology and realization which correlated to function modules is discussed. Resource management and task schedule in simulation grid system is effectively realized which is shown to enhance the effect of simulation running.
Due to the complex data grid environment with characteristics of uncertainty and instability, it is extremely important to provide an effective method of searching and managing the data storage resources in the data grid. This paper presents a new method for searching data storage resources with dynamic management in grid environment. The data grid middleware is designed with the auto-adapted software...
