Agent-based workflow model for enterprise collaboration
Workflow management system supports the automation of business processes where a
collection of tasks is organized between participants according to a defined set of rules to
accomplish some business goals. The service-orientated computing paradigm is
transforming traditional workflow management from a close, centralized control system
into a dynamic information exchange and business process. Moreover, agent based
workflow, from another point of view, provides a flexible mechanism for dynamic
workflow coordination at run time. In this context, the combination of Web services and
software agents provides great flexibility to discover and establish relationships among
business partners.
This thesis proposes an agent-based workflow model in support of inter-enterprise
workflow management. In the proposed model, agent-based technology enables the
workflow coordination at both inter- and intra- enterprise levels while semantic Web and
Web services based technologies provide infrastructures for messaging, service
description, service discovery, workflow ontology, and workflow enactment.
Coordination agents and resource agents are used with a Contract Net protocol based
bidding mechanism for constructing a dynamic workflow process among business
partners. The agent system architecture, workflow models and related components are
described. A prototype system is implemented for the purpose of designing and
developing role-feasible agents for simulating the formation process of a virtual
enterprise
Peer - Mediated Distributed Knowledge Management
Distributed Knowledge Management is an approach to knowledge management based on the principle that the multiplicity (and heterogeneity) of perspectives within complex organizations is not be viewed as an obstacle to knowledge exploitation, but rather as an opportunity that can foster innovation and creativity. Despite a wide agreement on this principle, most current KM systems are based on the idea that all perspectival aspects of knowledge should be eliminated in favor of an objective and general representation of knowledge. In this paper we propose a peer-to-peer architecture (called KEx), which embodies the principle above in a quite straightforward way: (i) each peer (called a K-peer) provides all the services needed to create and organize "local" knowledge from an individual's or a group's perspective, and (ii) social structures and protocols of meaning negotiation are introduced to achieve semantic coordination among autonomous peers (e.g., when searching documents from other K-peers). A first version of the system, called KEx, is imple-mented as a knowledge exchange level on top of JXTA
Forum Session at the First International Conference on Service Oriented Computing (ICSOC03)
The First International Conference on Service Oriented Computing (ICSOC) was held in Trento, December 15-18, 2003. The focus of the conference ---Service Oriented Computing (SOC)--- is the new emerging paradigm for distributed computing and e-business processing that has evolved from object-oriented and component computing to enable building agile networks of collaborating business applications distributed within and across organizational boundaries. Of the 181 papers submitted to the ICSOC conference, 10 were selected for the forum session which took place on December the 16th, 2003. The papers were chosen based on their technical quality, originality, relevance to SOC and for their nature of being best suited for a poster presentation or a demonstration. This technical report contains the 10 papers presented during the forum session at the ICSOC conference. In particular, the last two papers in the report ere submitted as industrial papers
