  • Agent-mediated electronic markets have been a grow-ing area of agent research and developmen tin recent year. There exist a lot of e-commerce sites on the In-ternet(e.g. Priceline, com, Amazon, com etc). These e-commerce site have proposed new business models for effective and efficient commerce activity. Intelli-gent agents have been studied very widely in the field of artificial intelligence, For purpose of this paper, an agent can act autonomously and collaboratively in a network environment on behalf of its users. It is hard for people to effectively and efficiently monitor, buy, and sell at multiple e-commerce sites. If we intro-duce agent technologies into e-commerce systems, we can expect to further enhance the intelligence of their support. In this paper, we propose a new coopera-tion mechanism among seller agents based on exchang-ing their goods in our agent-mediated electronic market system. G-Commerce. On G-Commerce, seller agents and buyer agents negotiate with each other. In our model, seller agents cooperatively negotiate in order to effectively sell goods in stock. Buyer agents coopera-tively form coalitions in order to buy goods based an discount proices. Seller agent's negotiation goods. Our current experiments show that exchanging mechanism enables seller agents to effectively sell goods in stock. Also, we present the Pareto optimality of our exchang-ing mechanism.

  • Recently mobile SFA(Sales Force Automation) system makes rapidly progress specially in industries like insurance, manufacture, and distribution. However, there are some problems that information about products and trades is not promptly shared among sales agents or customers, since the current mobile SFA system has simply extended the existing systems for sales management. In order to improve these weaknesses, we introduce LBS(Location Based Service) and mobile P2P(Peer to Peer) service into the existing systems, then design and implement the enhanced system (or mobile SFA using them. Through this improvement, our system makes it possible for customers or sales agents to quickly share various information and increases the efficiency of sales activity by facilitating the competition and cooperation among sales agents and reducing time-cost.

  • In this paper, we introduce the micro robot soccer playing system as a standard test bench for the study on the multiple agent system. Our method is based on following viewpoints. They are (1) any complex behavior such as cooperation among agents must be completed by sequential basic actions of concerned agents. (2) those basic actions can be well defined, but (3) how to organize those actions in current time point so as to result in a new stale beneficial to the end aim ought to be achieved by a kind of self-learning self-organization strategy.

  • A multi-agent technology has emerged as new paradigms that can flexibly and promptly cope with various environmental changes and complex problems. Accordingly, many studies have been carried out to establish multi-agent systems in an effort to solve dynamic problems in many fields. However, most previous research on the multi-agent frameworks aimed at, on the behalf of a user, exchanging and sharing information among agents, reusing agents, and suggesting job cooperation in order to integrate and assimilate heterogeneous agents. That is, their frameworks mainly focused on the basic functions of general multi-agents. Therefore, they are not suitable to the development of the proper system for a specific field such as a negotiation. The goal of this research is to design a multi-agent framework for the negotiation system that supports the evaluation of the negotiation messages, management of the negotiation messages, and message exchanges among the negotiation agents.

  • In a widely distributed environment, many occasions arise when people need to filter informationwith email clients. The existing information agents such as Maxims and Message Assistant have capabilities of filtering email messages either by an autonomous agent or by user-defined rules. FlexMA, a variation of FAMES (Flexible Asynchronous Messaging System) is proposed as an information filtering agent. Agents in our system can be scaled up to adapt user's various demands by controlling messages delivered among heterogeneous email clients. Several functionalities are split into each agent in terms of component configuration with the addition of multiple agents'cooperation and negotiation. User-defined rules are collected and executed by these agents in a semi-autonomous manner. This paper demonstrates how this design is feasible in a flexible message system.

  • Due to the increasing complexity to handle conflicts and interruptions caused by resource failures and rush orders, shop control is obliged to redesign its organization according to the changing demands of the manufacturing control. These demands are leading to the development of decentralization and gradually to their permanent optimization. As a result, a powerful modeling method which can be adapted efficiently is required. The use of agent theory enables specific modeling of the relevant shop planning activities. The planning activities are modeled in a so-called activity modeling through the definition of three classes of agents; Plan Agent, Manufacturing System Agent and Control Agent as well as the description of the cooperative relationship among these agents. On the basis of the activity model the agent-based shop control method is developed which emphasizes the distributed problem-solving and the cooperation with relevant agents.

  • 본 연구는 문제중심학습에서 튜터, 동료, 자기평가간의 평가점수를 비교하고 평가주체 점수간의 관련성과 평가주체별로 평가에 영향을 미치는 평가영역을 알아보는데 목적이 있다. 이를 위해 문제중심학습으로 수업받는 간호학과 학생 105명을 대상으로 문제중심학습 효과도구를 가지고 3차에 걸쳐 튜터, 동료, 자기평가를 실시하였다. 수집된 자료는 SPSS WIN(V. 12.0)으로 분석하였다. 연구결과 3차례의 수업 모두 자기평가 점수가 튜터, 동료평가 점수보다 높았다. 평가주체별 점수간의 관계는 3차례의 수업에서 튜터평가와 동료평가간에 관련성이 있었다. 평가주체별 평가에 영향을 미치는 평가영역은 튜터평가는 '문제해결능력'이었고, 동료평가와 자기평가는 '협동학습능력'이었다.

  • 해결해야 할 문제가 복잡해짐에 따라 소프트웨어의 구조가 대단히 복잡해지고 있다. 이는 데이터와 응용 프로그램 모두 동적 분산적 성격이 강해지고 있기 때문이다. 소프트웨어 시스템은 사용자간의 작업을 조정하는 역할뿐만 아니라 분산된 프로그램간의 협력기능을 관리하는 데에도 일조를 하도록 요구되고 있다. 소프트웨어 에이전트는 이러한 요구를 만족시키는 일반적인 메커니즘을 갖고 있다. 에이전트가 대단히 동적이고 분산된 환경하에서 효과적으로 주어진 작업을 수행하기 위하여 적응성을 가질 필요가 있다. 적응성은 에이전트 행동의 여러 차원에 존재하는 기능으로, 본 논문에서는 이 적응성을 에이전트의 관점에서 내부구조 살펴보고 튜토링 에이전트에 적용할 수 있는 적응형 에이전트 모델을 제시하고자 한다.

  • By employing primarily the Kendall's Concordance Test, the paper attempted to conduct an experts' evaluation on the interaction among the agents in Busan marine tourism cluster and recommend some measures for policy consideration for the cluster's activation. For this purpose, a conceptual framework was developed to guide the assessment by using inter-agent cooperation and network approaches regarding the nature of the marine tourism cluster. Such factors as cooperation, competition, relationship marketing, and networking were identified as critical. Findings of the study imply that Busan marine tourism cluster is at its embryonic stage and needs desperate measures for improvement in the inter-organizational cooperation and networking, the major regional characteristics that determine the competitiveness of marine tourism.

  • 본 논문에서는 가상 공유 기억장치(VSM)를 기반으로 에이전트들간의 통신 및 협조 가 이루어지는 분산 문제 해결(DPS)을 위한 개념적 모델을 제안하였다. 이 모델에서 DPS 시스템을 구성하는 모든 에이전트는 분산된 환경에 있는 모든 기억장치를 단일의 공유 기억장치로서 취급하며, 따라서 그 곳에 있는 모든 데이터와 작업, 실행 결과 등을 엑세스할 수 있다. 에이전트들이 데이타와 실행의 중간 결과 및 다른 에이전트에게 요 청할 작업등을 VSM에 출력하고, 또한 VSM의 내용을 읽거나 실행함 으로써 하나의 복잡한 문제를 협조적으로 해결하게 된다. 또한, 본 논문에서는 제안한 모델을 기반으로 DPS 시스템을 구축 할 수 있도록 Network Linda를 이용하여 DPS 시스템 개발 환경(DPS-VSM) 을 설계하였다. 또, VSM을 기반으로 하는 DPS 시스템을 시뮬레이션한 예를 제시함으로써 제안한 모델의 유용성을 보이고, DPS-VSM과 기존의 다른 DAL 프로그래밍 쉘의 특성을 비교함으로써 제안한 모델을 분석하였다.
