Abstract Service computing traditionally includes a centralized control structure. However, multi-agent theory and technology provide another way to realize service computing. In this paper a web service is viewed as an agent, called service agent, and thus service computing is regarded as a decentralized and distributed computing mechanism. Service agents can recognize and provide services for the service requests then aggregate together for the request satisfying. Based on a function ontology and automated mechanism design, the solution of request is obtained. Moreover, how to choose a solution as a 0-1 integer programming problem is formulated, and this problem is an NP-complete problem. A negotiation framework is provided to resolve this problem. In this framework, service requester and service agents come to an agreement by negotiating within finite rounds. A simulation is given to evaluate the negotiation framework.
