TL;DR: The Agent technology of the distribution artificial intelligence is adopted to suggest CAPP and production scheduling integration model based on Multi-Agent System(MAS) and this model is Dynamic Open Level/Layer(DOLL) control structure.
Abstract: The Agent technology of the distribution artificial intelligence is adopted to suggest CAPP and production scheduling integration model based on Multi-Agent System(MAS). This model is Dynamic Open Level/Layer(DOLL) control structure. The Contract Net protocol and active blackboard controller methods are adopted to realize information interaction and system execution. The prototype system based on this model is set up under the network environ so as to make the process planning and production scheduling Agent structure become the independent model which can better carry out the consultation feedback information. The scheduling process is simulated. The simulation results indicate that the system model suggested and the framework realization are correct and an effective way to solve the problem of scheduling bottleneck.

TL;DR: In this article, a dynamic scheduling simulation and optimization of carrier aircraft is developed based on multi-agent technique, where an interactional coordinated mechanism among agents is proposed to reduce the influence of system disturbance (a sort of uncertainty, such as fault, new task arriving) which result in re-scheduling trouble.
Abstract: Aiming at uncertainty and dynamic characteristic in scheduling of carrier aircraft,a dynamic scheduling simulation and optimization of carrier aircraft was developed based on multi-agent technique.The conceptual model for dynamic scheduling of carrier aircraft under uncertainty was established.The implicit function relationship of conceptual model among variable,objective and restriction conditions was described by multi-agent technique.An interactional coordinated mechanism among agents was proposed to reduce the influence of system disturbance(a sort of uncertainty,such as fault,new task arriving) which result in re-scheduling trouble.Through combination of contract net protocol and genetic algorithm,a hybrid optimization algorithm was developed to improve the problem solving capability of the dynamic scheduling model.Finally,a case about typical mission of carrier aircraft was given to improve the feasibility of simulation model and optimization algorithm.The capacity of the hybrid optimization algorithm was tested,and the influence of fault disturbance was analyzed by Sensitivity Analysis method.

TL;DR: In this article, an onboard intelligent mission planning for on-orbit servicing (OOS) mission is studied, where each SSc is supposed as an autonomy or agent They could perform planning onboard, communicate, and negotiate with other SScs.
Abstract: In On-orbit servicing (OOS) mission planning problem, mission sequences and orbital rendezvous trajectories for servicing spacecraft (SSc) servicing multiple targets would be optimized, aiming at reducing the mission cost, the time duration, or some other merits The onboard intelligent mission planning for OOS mission is studied in this paper Each SSc is supposed as an autonomy or agent They could perform planning onboard, communicate, and negotiate with other SScs A multi-agent system (MAS) model is firstly introduced And then, based on the MAS model, an intelligent planning method based on contract net protocol (IPCNP) is developed Simulations demonstrate the effectiveness of IPCNP

Journal Article
TL;DR: In this article, a distributed multi-agent based manufacturing organization structure is proposed, and several traditional scheduling methods are compared, and the traditional Contract Net Protocol(CNP) and its limitation are discussed.
Abstract: The control system of agile manufacturing systems should be capable of reconfiguring, communicating on webs, and cooperating with external systems Firstly proposed in the paper is a distributed multi-agent based manufacturing organization structure Then several traditional scheduling methods are compared,and the traditional Contract Net Protocol(CNP) and its limitation are discussed Finally,the procedure of manufacturing scheduling based on extended CNP is studied from two aspects of internal job-shops and inter-enterprises Especially,a multi-phase multi-task extended CNP aiming at task distribution among enterprises is designed
