본 논문에서는 독립 에이젼트 기반의 침입탐지 시스템을 구현하고자 한다. 침입 탐 지 시스템의 메시지 유실 및 메시지 내 정보에 대한 처리를 보다 안정적으로 제공하기 위해 단위침입 행동별로 학습된 모니터링 프로세스에서 전송되는 사용자 위협 행동 메시지에 대 한 처리를 담당하는 조정자 에이전트 시스템을 제안한다. 본 논문에서 제안된 조정자는 안 정화된 메시지 처리 문제 뿐아니라 기존모델의 에이젼트간 협력 작업에 의해 처리되었던 침 입 판단 기능 및 모니터링 프로세스들의 관리기능 또한 수행하도록 하게 된다. 따라서 시스 템의 유연성 및 확장성 향상을 도모하도록 하였다.

Many researchers have modeled complicated problems with distributed AI technologies in distributed environment. Especially, intelligent agent technology we often proposed among researchers as efficient method to solve the complicated problems because agent technology makes possibile to share different problem solving abilities among processors in distributed processing environment. In this paper, we propose multiagent system model to solve distributed scheduling problem. At this point we apple CSP techniques to the multiagent model as individual problem solving ability of member agents. Scheduling problem is divided into subproblems according to constraints by distributed resources, then each agent solves its subproblem using CSP solver in the proposed model. This method improves scheduling efficiency. For meeting scheduling problem of case study, we show CSP modeling process and suggest problem solving procedure by multiagent system model.

In order to provide efficient retrieving results for user query on the web environment, the various searching algorithms have developed and considered user's preference and convenience. However, the searching algorithms are developed on the horizontal and non hierarchical web environment in general and could not apply to the complex hierarchical and functional web environments such like the enterprise network. In this paper, we purpose the multi-agent based web mining system which can provide the efficient mining results to the user on the special web environment. For doing this, we suggest the network model with the hierarchical web environment and model the multi agent based web mining system which has four corporation agents and fourteen process modules. Then, we explain the detailed functions of each agent considered the hierarchical environment according to the module. Especially, we purpose the new merging agent and improved ranking algorithm by using the graph theory.

CASE도구의 일부로 제공되는 기존의 문서화 도구들은 개발자들을 위한 편리한 기능을 제공했지만, 문서화 참여자들 사이의 협동작업 및 정보교환을 효과적으로 지원해 주지 못했다. 협동작업 환경 및 정보교환 도구 지원의 미비로 인한 문서화 참여자들 사이의 의사소통 부족은 문서 사이의 불일치(Inconsistency), 누락(Incompleteness), 애매모호함(Ambiguity)을 발생시킨다. 소프트웨어 문서가 사용자 및 개발자를 위한 중요한 자료로 활용되기 위해서 협동 문서화 작업 환경의 구축과 정보 교환 도구의 지원은 필수적인 요소이다. 본 논문에서는 문서 상태와 사건을 중심으로 한 문서화 프로세스를 정의하고 문서 변경이나 삭제가 발생했을 경우, 이를 탐지하여 자동으로 개발자들에게 메시지를 보내주는 메시지 에이전트(Message Agent) 기반의 협동 문서화 작업 환경을 제안한다. 협동 문서화 작업 환경은 여러 명의 문서화 참여자들이 서로의 문서를 공유하며 작업할 수 있는 환경을 제공하며, 메시지 에이전트를 통한 메시지의 자동 전송으로 문서화 도중에 개발자가 직접 메시지를 작성하던 번거로움을 줄이고 문서의 질적인 향상을 기할 수 있는 장점이 있다.

최근 여러 기업과 단체들은 전자상거래 관련 분야에 대한 연구개발을 활발하게 진행하고 있다. 새로운 비즈니스 프로세스가 제안되고 있으나 상거래 변화에 동반되어야 하는 물류 부분에 대한 연구는 상대적으로 미흡하였다. 구체적으로 화주와 운송업체의 물류정보를 통합 관리하고 거래 상대를 중개하는 중개 시스템에 대한 연구가 필요하다. 본 논문은 화주와 운송업체에게 거래 상대를 연계하는 물류정보 중개 시스템을 소개하고 중개 에이전트를 제안한다. 제안된 중개 에이전트는 화주와 운송업체의 요구사항을 가능한 만족하면서도 빠른 시간 내에 거래 상대를 찾기 위하여 휴리스틱 방법을 이용한다.

The existing management job of research expenses has been divided into three parts： budget planning, budget draw-up, and exact settlement of budget. However, it caused some problems. Under this current circumstance it is required to obtain research expenses steadily, to operate efficiently and to use them clearly to solve such problems. As a result of a study on data warehouse development process of existing system integration company (Inmon, IBM) to reflect current trend described above, data warehouse development process of Inmon uses systematic and gradual access as a classical development cycle method. It causes overlap and feedback to the previous step in the process of each step Is requested. And another problem that it is difficult to toil what function refers and corrects data because functions and data are separated during performing development process at data warehouse development process of IBM is caused. Integrated management data warehouse development process of research expenses in the enterprise environment which applies UML at planning and analysis step, design step and implement and test step is suggested in this paper. Information retrieval agent uses existing budget plan DB, budget draw-up DB and budget settlement DB to find out information that a user wants to know. Information retrieval agent collects and saves information at integration database and information integration agent extracts, transports, transforms and loads the data. Information integration agent reduces a user's efforts to access to a number of information sources and check each of them. It also screens out data that a user may not need. As a result, integrated management data warehouse development process of research expenses in the enterprise environment reflects a user's requirements as much as possible and provides various types of information to make a decision which is needed to establish the policy of research expense management. It helps an end user approach his/her desired analysis information quickly and get various data from the comprehensive viewpoint rather than the fragmentary viewpoint. Furthermore, as it integrated three systems into one, it is possible to share data, to integrate the system, to reduce operating expenses and to simplify supporting environment for the decision making.

The concept of an agent has become important in computer science and has been applied to the number of application domains such electronic commerce and information retrieval. But, no one has proposed yet in software test. The test agent system applied the concept of an agent to software test is new test tool. It consists of the User Interface Agent. the Test Case Selection & Testing Agent and the Regression Test Agent. Each of these agents, with their intelligent rules, carry out the tests autonomously by empolying the object-oriented test processes. This system has 2 advantages. Firstly since the tests are carried our autonomously, it minimizes tester interference and secondly, since redundant-free and consistent effective test cases are intellectually selected, the testing time is reduced while the fault detection effectiveness improves. In this paper, by actually showing the testing process being carried out autonomously by the 3 agents that form the TAS, we show that the TAS minimizes tester interference. By also carrying out the 4 different types of experiments on the RE-Rule, CTS-Rule, overall TAS experiment, and the fault-detection effectiveness experiment on the RE-Rule, we show the cut-down on the testing time and improvement in the fault detection effectivity.

As Internet and Internet users are rapidly increasing and getting popularized in the world the existing firewall has limitations to detect attacks which exploit vulnerability of web server. And these attacks are increasing. Most of all, intrusions using web application's programming error are occupying for the most part. In this paper, we introduced real-time web-server agent which analyze web-server based log and detect web-based attacks after the analysis of the web-application's vulnerability. We propose the method using real-time agent which remove Process ID(pid) and block out attacker's If if it detects the intrusion through the decision stage after judging attack types and patterns.

Keen competence in business environments induces companies to introduce Supply Chain Management (SCM), which is accelerated by emerging information technology. Consequently, supply chain integration requires interacting and information sharing among the companies participating in the supply chain. Web services, platform independent technologies, are recently used for SCM. However, web services themselves do not provide high level supply chain integration. Therefore, the ways to control and manage global processes over supply chain need to be developed. In this paper, we introduce a method of executing and managing supply chain process using Business Process Management (BPM) system. BPM system is a software system to support an efficient execution and management of complex business processes, and it is applied to supply chain processes . The supply chain processes can be regarded network of activities, each of which is served as web service and related to one of the participants. Our approach enables not only efficient managing but also effective monitoring of the process, which can be a good basis for improvement of the processes. For a speedy execution of processes, we provide a method to support decision making in course of executing process by software agents, which are also web services.
