Today, more and more people like to take kinds of vehicles to travel, there are so many tourists and vehicles at every scenic, as a result, how to effectively solve problems between ecological environment protection and tourist development, how to wisely handle abnormal events of the scenes, such as quick response for incidences, safety of tourists, people/vehicles evacuation and so on. In this paper,...
Sound agents is an art installation relating real space and virtual sound space. It follows previous work on virtual agents and autonomous characters in 3D immersive spaces. However in sound agents, each virtual entity will not be a visual character but an invisible sound agent producing music, which will have its own autonomous behavior. Therefore the ambient music is dynamically spatialized in the...
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...
In peer-to-peer (P2P) systems, one important technique to improve the effectiveness of blind search is to proactively replicate file, which can lighten peers' load as well. But for autonomy and selfishness of peers in P2P systems, some peers are not willing to contribute their storage to save replications, which cannot be created successfully in this case. This paper presents a replication method...
Which attributes are the basic ones when we describe the rational agent's internal states? How many attributes are sufficient enough for application? Those have been pending problems. This paper analyzes the limitations of the past research in this field, presents rational agent's attributes of KOCBDI and illustrates, by means of simulated RoboCup, that KOCBDI is independent.
Negotiations are one of the most common ways that agents in a multi-agent system use to reach agreements. As negotiations commonly are multi-lateral and multi-issue, these processes become more difficult. Moreover, in real-world applications in which real-time agents are needed, this issue becomes more important. Autonomous agents should be able to decide what to propose in each round of negotiations...
This paper is brought into being from the experience during the personalized information service system in digital library is developed. This system based on agent aims to improve the service quality and level of college library information management system under the concept of Lib2.0. Based on analyzing the recent research and application status of Lib2.0 personalized information service, and researching...
This study addresses problems of service design in movie theaters and proposes a new auction mechanism that addresses seat reservations. In movie theater services, the movie price is generally fixed; moreover, it does not depend on the quality of contents or the theater seat. Therefore, such a service mechanism by the fixed pricing cannot reflect the value of movie contents. In this study, introducing...
Digital systems have been rapidly evolving within highly dynamic and unstructured environments, where the lack of a central authority forces entities to interact with each other through collaboration and negotiation. Digital agents often use Trust models in order to compute the level of trustworthiness of the partner they want to collaborate with. Unfortunately, due to the evolution speed of open...
In e-commerce, the negotiation based on multi-agent has become an active field. This paper brings a new multi-agent auto negotiation model which is done using multi-agent system, fuzzy evaluation algorithm and game theory. Firstly, we design negotiation model; secondly, we analyze the flow; finally, we build a negotiation platform in according to combination with Web technique and jade. The model...
Existing density-based data stream clustering algorithms use a two-phase scheme approach consisting of an online phase, in which raw data is processed to gather summary statistics, and an offline phase that generates the clusters by using the summary data. In this paper we propose a data stream clustering method based on a multi-agent system that uses a decentralized bottom-up self-organizing strategy...
Complex adaptive system (CAS) theory is used to analyze the e-commerce system and the concept of e-commerce transaction network is proposed. The e-commerce transaction network can be viewed as a complex network which is constructed by transaction behaviors between buyers and sellers. Then we give a formal definition of the e-commerce transaction network and establish a multi-agent model for e-commerce...
Although the financial crisis shrinks oil price, human as an entire race still face the future of a hot, flat and crowded world [1]. Therefore, a critical transformation from our traditional energy consumption manner of fossil fuel combustion must be made. After years of endeavor in research and experiment, a number of Renewable Energy Sources (RES) has already become technically available as alternatives...
Price dispersion is an indication about the efficiency of market. An evolution model of price dispersion (EMPD) is put forward in order to research the efficiency of C2C e-business market. By concluding the influence factors of price dispersion and analyzing the trade behavior in C2C e-business market, four representative factors that are business number, business credit, customer type and transfer...
A new multi-agent automated negotiation model is developed and evaluated, in which two competitive agents, such as the buyer and seller, have firm deadlines and incomplete information about each other. The negotiation is multi-dimensional in different cases. The model improves the model of Wooldridge and that of Sycara to a certain extent. An e-commerce model based on multiagent automated negotiation...
In this paper, we present a description model of a trust network graph (TNG)-for multi-agent-based e-commerce systems, which is similar to the relationship network formed among people's transaction activities in the real-world. The method assumes that a multi-agent system in a domain constitutes a community and so the trust network is modelled by the means of a graph in the community. Several notations...
Resources allocation is complex undertaking problem in distributed resources share problems. In this work, we consider the problem of engineering agents that act as proxies for the procurement of computational and data resources. By using economic models, mechanisms such as auctions may appropriate for the management of these problems. In this paper, we provide the design and theoretical analysis...
This paper presents a complex interaction delayed swarm model with a general topology to study the collective behavior of a group of autonomous agents using the nearest neighbor rulers in the presence of communication delays. It is proved that under certain conditions the swarm members will converge to a finite region around the swarm weighted center and move together in a cohesive cluster following...
According to the sociological principium, this paper designed a model aimed at social networks and implemented it using the multi-agent system. Based on this model, we established a simulation system to research the evolution of colony in the social networks, analyzed the effects on the evolution by the characteristics of individuals and achieved meaningful conclusions.
In ubiquitous computing the multi-agent system can provide intelligent services to the users by effectively utilizing the resources distributed in the environment. The traditional load balancing approach based on the load condition of the nodes is not suitable to the multi-agent system (MAS). In this paper we propose an efficient load balancing scheme for MAS employing the models formulated to identify...
