Cooperation mechanisms for agents monitoring service-based workflows are a means to address the increasing complexity of modern enterprise architectures. These mechanisms are inspired by existing biological mechanisms and extend an existing decentralized monitoring architecture in order to handle deviations from service level agreements autonomously. As the core cooperation mechanisms have been subject...
Successful negotiators prepare by determining their position along five dimensions: legitimacy, options, goals, independence, and commitment. We model business relationships in terms of these dimensions and two primitive concepts: intimacy (degree of closeness) and balance (degree of fairness). The intimacy is a pair of matrices that evaluate both an agent's contribution to the relationship and its...
The conceptualization and ongoing implementation of a network and service infrastructure for SMEs that bases on biologically inspired similes for service mediation needs thorough simulation and emulation capabilities that accompany that development. Digital ecosystems (DE) are demand-driven self-organising agent environments exhibiting complex behaviour during utilisation and growth. To optimise this...
Web based applications and tools offer a great potential to increase the effectiveness of information flow and improve communication among disparate agents in support of distributed operations. One of the factors that hinders the integration and interoperability of information models, is a lack of common, shared vocabularies. This paper discusses research aimed at placing shared vocabularies at the...
Manufacturing plants need to be flexible and evolvable, which might be achieved by stepping up the level of abstraction at which they are designed. In this work a methodology that starts by creating ontologies of the plants that represent information flows is proposed. Agent-based technology is then used to provide systems with the ability to evolve. The proposal is designed to suit the needs of SME'...
Bayesian belief propagation is flexible and highly adaptable in not only machine learning and artificial intelligence methodologies, but also to newer forms of learning involving agent interactions in digital ecosystems, specifically multi-agent systems. One important property of such systems is agent autonomy. An aspect of agent autonomy, enactive knowledge, is investigated here through a Bayesian...
With the rapid advance of information technology, supply chains evolved from clusters of connected companies to a virtual e-marketplace that serves as a central hub for many companies that buy and sell. Over this large community of companies supply chains can be dynamically formed by mediator agents. From the view of an ecosystem, the companies that are connected in the e-marketplace can be viewed...
