이 연구는 웹 기반 화상회의 시스템에서 지능적인 에이전트들을 통해 회의 소집에 들이는 노력을 최소화함으로써 여러 참여자들에게 동기적 협력을 보다 편리한 형태로 지원해 주는 시스템에 대해 연구하는 것이다. 이 시스템은 멀티 에이전트 구조를 가지며, 에이전트들 사이의 통신은 KQML을 이용한다. 이것은 시스템에 새로운 에이전트를 추가할 때에 에이전트들 사이의 이형질성을 극복찬 수 있도록 해준다. 이 논문에서는 웹 화상회의 시스템을 위한 멀티 에이전트들의 전체적인 구조를 제안하고, 이들 에이전트돈 사이의 KQML 메시지들의 흐름에 대하여 자세하게 소개한다.

A multi-agent system designed to represent newly deregulated electricity markets in the USA is aimed at testing the capability of the multi-agent model to replicate the observed price behavior in the wholesale market and developing a smart business intelligence which quickly searches the optimum offer strategy responding to the change in market environments. Simulation results show that the optimum offer strategy is to withhold expensive generating units and submit relatively low offers when demand is low, regardless of firm size; the optimum offer strategy during a period of high demand is either to withhold capacity or speculate for a large firm, while it is to be a price taker a small firm: all in all, the offer pattern observed in the market is close to the optimum strategy. From the firm's perspective, the demand-side participation as well as the intense competition dramatically reduces the chance of high excess profit.

Sharing power data between electrical power grids is crucial in energy management. The multi-agent approach has been applied in various applications to improve the development of complex systems by making them both independent and collaborative. The smart grid is one of the most intricate systems that requires a higher level of independence, reliability, protection, and adaptability to user requests. In this paper, a multi-agent system is utilized to share knowledge and tackle challenges in smart grids. The shared information is used to make decisions that aid in power distribution management within the grid and with other networks. The proposed multi-agent mechanism improves the reliability of the power system by providing the necessary information at critical times. The results indicate that the multi-agent system operates efficiently and promptly, making it a highly promising candidate for smart grid management.

Various studies have been performed to coordinate robots in transporting objects and different artificial intelligence algorithms have been considered in this field. In this paper, we investigate and solve Multi-Robot Transportation problem by using a combined auction algorithm. In this algorithm each robot, as an agent, can perform the auction and allocate tasks. This agent tries to clear the auction by studying different states to increase payoff function. The algorithm presented in this paper has been applied to a multi-robot system where robots are responsible for transporting objects. Using this algorithm, robots are able to improve their actions and decisions. To show the excellence of the proposed algorithm, its performance is compared with three heuristic algorithms by statistical simulation approach.

Technological innovations over the years have accentuated the workings in corporate- connected organizations and different application platforms. Hence, a unified management information system (MIS) that can utilize the Web and propel programming developments is required. Software agents, the latest developments in computer software technology, can be utilized to rapidly and effortlessly build integrated information systems. Consequently, 59 research papers on the use of software agents in MIS were identified from top 40 MIS journals published between 2007 and 2017. Then, we reviewed and classified all the research papers according to two categories: application fields and application categories. The application fields consisted of eight sub-groups: manufacturing, telecommunication systems, traffic and transportation management, information filtering and gathering, electronic commerce, business process management, entertainment, and medical care; whereas the application categories consisted of three sub-groups: multi-agent systems, personal assistants, and multi-agent simulation. The research papers were further divided into journal and year of publication, and journal and application field. The objective of our research was to understand the trend of the use software agent technology in MIS by examining the published research paper beside to add knowledge and content to the information system academic discipline.

In this paper, a development of agent-based IEDs(Intelligent electronic devices) for integration control of building microgrid in smart green building are proposed. To manage and control this complex energy system of smart green buildings, multi-agent system based networks is needed. Thus, several IEDs for utilizing multi-agent system are developed and modified for the their verification of performance as agent modules functions in the integrated experimental equipment. The good performance of these IED agents are verified from experimental results obtained from seamless bi-directional communication by SOAP/XML protocol between PC agent and IED agent.

멀티 에이전트(Multi-Agent)들이 상호 연동하여 공통의 목적을 수행하기 위해서는 에이전트를 관리하는 매니지먼트 에이전트(Management Agent)가 요구되고, 주어진 환경에서 획득한 제한된 지식을 효율적으로 이용하는 방법이 필요하다. 본 논문에서는 네이브 베이즈 이론을 적용하여 각 에이전트의 속성값(Attribute Value)에 따라 매니지먼트 에이전트가 각 에이전트를 효율적으로 관리할 수 있는 NBMA(Naive Bayes Management Agent)를 제안하고 이를 이용한 미팅 참가 결정 에이전트를 제안한다. NBMA는 고유한 속성을 지닌 여러 개의 하위 에이전트와 그들을 관리하는 매니지먼트 에이전트로 구성되어 있으며 매니지먼트 에이전트는 하위 에이전트들의 고유한 속성에 대한 메타지식을 이용하여 관리 하도록 한다. 하위 에이전트간에는 상호 조건부 독립(mutually conditional independence) 가정하에 복수의 속성값을 취하며 이러한 속성값에 따라 매니지먼트 에이전트가 조정과 의사결정을 하도록 한다.

Service restoration is one of the most important missions in distribution system operation. This paper proposes a multi-agent system approach to distribution system restoration. Every relay is developed as an agent by adding its own intelligent, self-tuning and communication ability. The relay agent independently calculates and corrects its restoration index through communication with neighboring agents and its own intelligence. The proposed algorithm is applied to a simple network to demonstrate its soundness and effectiveness.
