[Session C7. FMS/CIM] 에이전트 기반 제어구조를 위한 협상 프로토콜

To implement more flexible manufacturing system, the flexibility of each controller in scheduling and planning has to be enhanced. Many researchers are interested in DAI(Distributed Artificial Intelligence) technologies to apply the decision-making system of SFCS(Shop Floor Controller System). We here propose the agent-based control architecture and a novel negotiation protocol named for MANP(Mobile Agent-based Negotiation Protocol). In the proposed control architecture, each agent coordinates the activities and negotiates with other agents to improve the system performance. Also, the bid manager system is introduced for systematic negotiation among agents. MANP is based on the mobility of an agent. The clone of an agent travels over the controllers to negotiate with other agents. Negotiation process in MANP has four phases - 1)preparation, 2)cloning, 3)traveling and evaluation, 4)awarding.
