Motivated by the increased bioinformatics service-based offering on the Grid, we envisage a new model for programming the Grid at a semantic, knowledge-based level of abstraction through the use of argumentative agent technology. In this setting, agents are associated with roles of service requestors, service providers and brokers. This new model provides an enhanced service composition model for grid applications, whereby service requestors, providers and brokers can profit from the dynamic composition of Grid resources and services into executable workflows. This model would thus have considerable impact on existing business practices, by enhancing the role of Grid in current business applications. Within this model, argumentative agents are equipped with methods for negotiation with other agents. Agents act on behalf of their owners, be it in the consumer, provider or broker roles, or a combination thereof. With the support of argumentation processes, they decide how to fulfill the demands of their owners by creating, managing and joining virtual organisations, understood as societies of agents, while pursuing their own goals. 249 1.
