摘　　要：为了对车间制造系统实施有效动态调度,提出了一个动态调度控制器的设计框架,并详细阐述了它的功能模块和工作流程。控制器采用基于过程规范语言本体论的工艺规划信息表示和多步骤适应调度策略,并从知识库中获取规则,使用在线仿真的方式对其进行评价。这些技术的应用保证了控制器与车间内部其他异构信息系统间有效地传递工艺规划信息,并具有很好的调优能力。最后,给出了一个制造企业的应用实例,验证了该设计框架的可行性和有效性。To implement dynamic scheduling in workshop manufacturing systems, a design framework of dynamic scheduling controller was proposed. Function modules and working process of the controller were discussed in detail. A process specification language ontology-based representation of process plan and a multi-pass adaptive scheduling strategy were utilized in the controller, which acquired rules from the knowledge base and applied the build-in online simulator to evaluate rules. These technologies enabled effective communications of process planning information between workshop and other heterogeneous information systems with good fine-tune ability. Finally, an application case in a manufacturing enterprise was provided to validate the feasibility and effectiveness of the proposed framework.
