Request Based Virtual Organisations (RBVO): An Implementation Scenario

Evolving e-commerce technologies increasingly enable organisations to participate in different types of network forms or in electronic markets with previously unidentified trading partners. Virtual organisations (VO) take different forms, have varying lifecycles and involve different scope and depth of relationships. This paper examines the literature in terms of the terminology of virtual organisations, the business drivers, the common theoretical concepts and models as well as the enabling technologies. A specific form of VO, Request Based Virtual Organisation (RBVO), is then considered in relation to these VO variants, particularly as realised through the practical work done within the framework of the EU sponsored LAURA project that facilitates interregional zones of adaptive electronic commerce.

Agent-based service-oriented collaborative architecture for value chains of SMEs

Current ICT trends provide new opportunities to implement some well-known models of e-collaboration between business partners, namely virtual organizations. The orientation towards enterprise social computing naturally complements the way companies do business with each other, thus the new service oriented architecture (SOA) and Web 2.0 based solutions can help to develop systems better suited for modern business needs. This paper presents an architecture based on SOA and Intelligent agents, which is aimed to address the needs of European SMEs involved in ERP software business. The solution is based on the concept of digital business ecosystem, an environment and software infrastructure, which can help a community of potential business partners to establish and maintain valuable business relationships. Such ecosystem provides its members with value-added services like reputation management, peer-to-peer negotiation of business terms and flexible partner search through usage of Intelligent Agents technology in overall SOA-based framework.

A Service Oriented and Agent-Based Architecture for the e-Collaboration of SMEs

The concept of a Service-Oriented Architecture (SOA) to flexibly address business needs with the use of Information Technology (IT) is increasingly being recognized as important for a company’s agility and responsiveness to change. A SOA approach can also help to design more agile web portals, in order to enable companies to increase their responsiveness and adaptability with regards to addressing a business opportunity as a collaborative Virtual Organization (VO). Value can be added to the operations of such a VO with the use of Intelligent Agents to automate the processes of finding collaboration partners and negotiating the creation of VOs based on user-defined business rules. This paper discusses these concepts and their benefits for Virtual Organizations based on the work of a European Union (EU) co-funded Information Society Technologies (IST) project examining these issues for Small and Medium Enterprises (SMEs) in the European Enterprise Resource Planning (ERP) industry.

Dynamic Management of Business Service Quality in Collaborative Commerce Systems

The importance of e-business services quality continues to increase, as the use of e-commerce to support business activities becomes a routine practice for many enterprises. Companies need robust, predictable and efficient services that they can rely upon. This paper explores ways of how e-business quality can be established, monitored, reported and managed. A review of the literature considers the work recently undertaken in both business-level quality of service (QoS) and the QoS issues at the infrastructure level, as well as the relationship between these two areas. From a practical research perspective, the work within the framework of the EU-funded LAURA project is presented. The key goal of this project is to facilitate interregional zones of adaptive electronic commerce using the potential of the ebXML architecture. A Dynamic QoS Management framework is proposed to inform the implementation of QoS and SLA concepts within the LAURA project.

Development of distributed systems with Java and CORBA issues and solutions

This paper summarises experience gained designing, developing, deploying and promoting distributed objects systems using JavaTM platform, Common Object Request Broker Architecture (CORBATM) and the World Wide Web during more than 3 years. The main question to be answered is: “How to build distributed business information systems with reasonable costs and time to market?” Paper provides three contributions to the study of distributed object computing in practice. First, we outline generic system architecture, which is quite common for many applications, and identify some issues that are important in applications of this type. Second, we discuss our solutions, which proved to be reusable across several different projects. And third, we present analysis of our CORBA components and Java class libraries from the reusability point of view.
