Service networks represent a flexible way for delivering services to customers. In earlier work, we have applied the e-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 reflects(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 evalue 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)
There are several problems related to security in computer networks. In this work only detection of masquerade attacks is explored. A masquerade attack occurs when an illegitimate user tries to impersonate a legitimate user; therefore, the masquerade user gets the privileges from the legitime user account. The task of detecting masquerade users is not easy(More)
Commercial services become increasingly important. Complex bundles of these services can be offered by multiple suppliers in a service value network. The eservice 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 the(More)
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 evalue methodology to conceptually model such networks, as a design task. This paper proposes an approach to semi-automatically generate such service value(More)
