Abstract: CNP is widely used in manufacturing systems based MAS (multi agent system) to solve scheduling and controlling problems. However, it has aeveral defects in solving real problems. A new method denling with task distributing and scheduling is presented and that is CNP combined with GPGP and TAEMS, and uses it in MM- MES, a manufacturing execution system based MAS, to research distributed manufacturing system’s scheduling and coordination.

Key words: Contract net protocol, GPGP, MAS, Shop floor scheduling, TAEMS
