Plan, Commit, Execute Protocol in Multi-agent Systems

In this paper we introduce changes made in Plan/Commit/Execute negotiation protocol originally developed for Agent Cooperation System and practically used in Chilled Water System application. This protocol is suitable for systems where the commitment of resources and execution of a plan require separated communication phases. The extension of the protocol with Reject Proposal message that is used for canceling unsatisfactory proposals is the most significant change. We also describe the deployment of the protocol in new version of Multi-agent System for Manufacturing.
