用黑板模型和专家系统进行注塑模初始设计

Building an Expert System for Injection Molding Design Using a Blackboard Model

介绍了将专家系统和黑板模型技术用于注塑模初始设计的智能CAD系统,提出了一个通过黑板模型组织协调各知识元操作的新的工程设计思想。这种黑板模型的应用可使系统随不同领域的用户以模块的形式进一步扩充和开发,该系统具有如下特点:灵活的建模和修改功能;支持再设计的设计思想;数值计算与图形功能相结合;对设计过程能够进行有效的诊断。

An expert system is developed for injection mold design using a blackboard model.A new engineering design approach which relies on the co-operation between multi-knowledge sources through a blackboard model has been proposed.The blackboard model allowed us to develop the system in a modular way.The system provides the following abilities that is flexsible model building and easy modification, supporting method for redesign, a hybrid function with numerical computations and graphics and effective diagnosis of the design process.Finally, It is applied to the initial design of the injection mold design.
