Integrating E-Business XML Business Forms and Rule-Based Agent Technologies

EXPERT SYSTEMS, Issue 5 2001
Tod Sedbrook
This study investigates the role of extensible mark-up language (XML) business forms and agent-based computing to support negotiation, management and implementation of inter-organization business processes. We explore recently proposed standards for representing artificial agent exchanges through rule-based inference. An XML representational syntax for standard business forms is developed and applied to augment rule-based agents. A prototype investigates ways to combine knowledge-based agents and business forms to assist business and customers in Web-based conference registration. The implementation helps guide customer decisions and the combination of business forms and rules promotes understandability, testability and adaptability of the registration system. [source]

A conceptual framework for agent-based agile manufacturing cells

INFORMATION SYSTEMS JOURNAL, Issue 2 2004
Jianming Yu
Abstract., Agile manufacturing techniques are perceived as the manufacturing systems of the future. Agile manufacturing cells are dynamic and reconfigurable and the modelling of the manufacturing cells and its interaction mechanism is critical to its successful use. This paper deals with the architecture and cooperation mechanism of web-based agile manufacturing cells. Based on an analysis of structure and organization requirements of agile manufacturing cells and a comparison of three basic architectures of manufacturing systems, the quasi-heterarchical architecture is used for the agile manufacturing cell. Functional layers are defined in this architecture to make the cell's control system reconfigurable and reusable. Agent technology is adopted for implementation of each layer's functions to establish an agent-based model of agile manufacturing cells. Four types of agents including cooperation agent, job management agent, resource broker agent, and resource control agent are defined, and their functions discussed. Finally, a real time interaction mechanism of the agents is presented by considering the activities during the agents' cooperation in an agile manufacturing cell. [source]

Multi-agent application of substation protection coordination with distributed generators

EUROPEAN TRANSACTIONS ON ELECTRICAL POWER, Issue 5 2006
H. Wan
Abstract This paper presents new explorations into the use of agent technology applied to substation protection coordination of power systems. The impact of distributed generators (DG) on protection coordination in substation with different locations is discussed first. Then a coordination multi-agent system is proposed with the functions of the agents described. In the proposed system, communication will play an important role to provide more information for the relay coordination besides the relay settings. Relay coordination strategy is also discussed and communication simulation has been carried out on the Java agent development framework (JADE) platform. The simulation results shows that proper protection coordination can be achieved by the proposed coordination strategy and information communication. Copyright © 2006 John Wiley & Sons, Ltd.

An agent-oriented and knowledge-based system for strategic e-procurement

EXPERT SYSTEMS, Issue 1 2004
C. F. Cheung
Abstract: This paper presents an agent-oriented and knowledge-based system (AOKBS) for strategic e-procurement. The AOKBS has been designed to capture and leverage the knowledge of an enterprise to generate dynamic business rules by which an effective procurement strategy can be generated based on enterprise needs and the analysis of relevant market conditions. The performance and practices of the suppliers can also be evaluated and captured continuously, respectively, by the AOKBS. Artificial intelligence technologies such as case-based reasoning and agent technology are incorporated for decision analysis. A prototype e-procurement system has been built and implemented successfully with a multinational manufacturer. [source]

Multivariate Bayesian regression applied to the problem of network security

JOURNAL OF FORECASTING, Issue 8 2002
Kostas Triantafyllopoulos
Abstract An Erratum has been published for this article in Journal of Forecasting 23(6): 461 (2004). This paper examines the problem of intrusion in computer systems that causes major breaches or allows unauthorized information manipulation. A new intrusion-detection system using Bayesian multivariate regression is proposed to predict such unauthorized invasions before they occur and to take further action. We develop and use a multivariate dynamic linear model based on a unique approach leaving the unknown observational variance matrix distribution unspecified. The result is simultaneous forecasting free of the Wishart limitations that is proved faster and more reliable. Our proposed system uses software agent technology. The distributed software agent environment places an agent in each of the computer system workstations. The agent environment creates a user profile for each user. Every user has his or her profile monitored by the agent system and according to our statistical model prediction is possible. Implementation aspects are discussed using real data and an assessment of the model is provided. Copyright © 2002 John Wiley & Sons, Ltd. [source]

Applying intelligent agents technology in a collaborative work environment

INTERNATIONAL TRANSACTIONS IN OPERATIONAL RESEARCH, Issue 1 2003
Nikos Karacapilidis
The current state of the art in computer,mediated collaborative work is mainly limited by the fairly primitive discourse structures that most asynchronous conference systems implemented so far provide and because they lack consensus seeking and problem solving abilities. To address these issues, we first propose a refined model of the discourse acts met in a collaborative work environment. In the sequel, using this model in the context of an already implemented system, we apply intelligent agents technology in order to enhance and facilitate collaborative work. The overall approach combines concepts from the AI and CSCW disciplines, while aims at giving a highly active role to the participants involved in such environments. [source]
