Enterprises increasingly jointly participate in service value webs. They do so because enterprises can then offer services they could not offer on their own. In earlier work, we have developed the e 3 value methodology to conceptually model such networks, as a design task. This paper proposes an approach to semi-automatically generate such service value(More)
In this paper we present a framework for dynamic service bundling, which focuses on the exchange of valuable outcomes between customers and service suppliers. The approach is based on three components: A customer, a broker and a pool of suppliers. The broker is in charge of matching the customer and supplier perspectives and performing a cluster-based(More)
This paper presents a novel approach to automatically generate e 3 value instance models, based on skeletal design techniques. The approach has three phases. While the first two phases are related to the generation of a value activity network based on a given value skeleton, the third phase matches the elements of the value network with the capabilities of(More)
Service networks represent a flexible way for delivering services to customers. In earlier work, we have applied the e 3-value methodology to conceptually model such networks. This paper, however, presents an approach for composing Service Value Networks (SVNs) based on customer and supplier perspectives. A broker is in charge of composing a SVN that(More)
Commercial services become increasingly important. Complex bundles of these services can be offered by multiple suppliers in a service value network. The e 3 service ontology proposes a framework for semi-automatically composing such a network. This paper addresses research challenges in service value network composition. As a demonstration of the state of(More)
Security in computer networks is an issue of special interest due to the importance of information inside organizations. Besides, a lot of communication actually involves computer networks, so it is necessary to provide security within. There are several problems related to security in computer networks. In this work only detection of masquerade attacks is(More)
A collaborative network is a network consisting of a variety of autonomous actors (e.g. enterprises, organizations and people) that collaborate to better achieve common or compatible goals. A collaborative network starts with a contract and then the collaboration partners conduct business as described in the contract. Before engaging in such a(More)
We present an interactive demo that illustrates the performance of our multi-agent-based system for trading 'green' energy. The system implements the NRG-X-Change concept and uses real-life data for energy consumption. NRG-X-Change encourages prosumers to locally trade their excess of energy while payments are carried out using NRGcoins, which is a novel(More)
