Abstract: A realtime dynamic carrier aircraft task scheduling model is developed based on the multiagent system (MAS) technology with full consideration of faults and maintenance effect on the operation flow. A flexible threelayer mixed control structure of the model is established through systematic analysis of the basic operation flow of carrier aircraft on a ship. A globallocal interactive coordinated mechanism based on contract net protocol (CNP) is proposed which takes into consideration system disturbances (such as failures) to improve the negotiation efficiency among agents and eliminate the effect of the rescheduling of carrier aircraft. In addition, the abstraction principle and an open internal structure for individual agents is provided, and the basic scheduling arithmetic for carrier aircraft based on MAS is discussed in detail. Finally, the model is validated by the simulation of a typical task of carrier aircraft under certain reliability and maintainability requirements, and a carrier aircraft sortie ability curve is obtained which exhibits the same trend as the actual scheduling process.
