In the context of a service-oriented architecture, agents responsible for workflow management can subdivide their goals in sub-goals, generate a utility function from each sub-goal and set up a negotiation process with the agents associated to one or more Web services and respo...

Since agents are selfish and exploit local knowledge about their actions as well as the environment, delegators face the hazard of losing outcome due to self-serving behavior of the “employed” agent. This research work adopts the economic theory of agency to study delegation relationships in multiagent sy...
