敏捷制造系统的基于Agent的混合调度

Multi-agent Based Hybrid Scheduling Strategy Agile Manufacturing System

针对敏捷制造调度环境的不确定性和动态性,研究了基于分布式多Agent的敏捷制造系统控制结构及混合调度策略。首先,提出多Agent制造控制结构,该结构兼有Agent的自治性和递阶组织(或动态逻辑单元)的协调性。接着,研究了结合模糊规划与模糊合同网的混合作业车间调度方案。该方法具有静态调度方法的精确性和合同网方法的动态、灵活性。最后设计算例仿真并验证了方法的可行性与效率。

For the condition of fuzzy and dynamic of agile manufacturing, a multi-agent architecture of agile manufacturing system and a hybrid strategy for scheduling were proposed. Firstly, a distributed multi-agent based manufacturing structure was proposed, which has characteristics of self-determination grounded on multi-agent as well as harmony grounded on hierarchical structure or dynamic logical unit. Then, based on the fuzzy theory and method, a hybrid shop floor scheduling strategy was studied that combines fuzzy programming with fuzzy Contract Net Protocol. The hybrid strategy has both virtues of precision of static programming and flexibility of Contract Net Protocol. Finally, a numeric case was simulated to test the feasibility and efficiency of the proposed approach.
