MAS-based negotiation mechanism for ship multi-project scheduling

Owning to the manufacturing environmental incertitude and complexity in multi-project shipbuilding enterprises, MAS technology is induced to ship multi-project scheduling system. For the purpose of realizing the dynamic and nearly optimal scheduling with agility and adaptability between distributed ship multiple projects, ship multi-project scheduling system framework and MAS-based system model is developed. A negotiation mechanism for ship multi-project scheduling is proposed to coordinate these ship project agents. Modified contract net protocol is used to settle the critical resources assignment in ship multi-project scheduling. An integrated scheduling optimization strategy is used to deal with the scheduling optimization problems in ship multi-project enterprise. At last, MPPSMA system which is developed on this basis verified the correctness of MAS-based negotiation mechanism for ship multi-project scheduling.
