【摘要】 模具成型技术已成为当代制造业生产的重要手段和工艺发展方向。制造业水平的高低很大程度上取决于模具工业的水平。对模具开发过程的知识进行研究,建立有效的管理系统,是中国模具工业与世界接轨,为相应产业服务的必要步骤。本文首先介绍了知识的概念和知识管理的理论,在此基础上引申出模具知识的特点。然后基于A公司的汽车塑料模具开发流程,分解出各开发步骤中需要的知识,并建立此知识系统的层次框架结构,在此过程中也介绍了相关的软件应用和系统集成平台。然后在知识库的理论基础上,介绍了知识的表达形式,同时基于A公司报价过程中的实际需求,导出了报价过程中结构化知识的概念并针对此结构化知识介绍了框架式表示法和产生式规则表示法,同时研究了利用框架式表示法和产生式规则表示法表达模具报价知识的过程。最后本文研究了模具开发中以专家知识作为表现形式的隐性知识,并借用六西格玛问题处理的方法,建立了A公司的案例知识格式,以基于案例推理的方式,建立了利用专家知识推导注塑缺陷问题的知识库。本文的研究结果,可用于指导模具的开发过程,以达到提高效率,避免因人成事的旧开发模式。
【Abstract】 Plastic injection tooling has been becoming an important approach in the industrial more and more; somehow, plastic manufacturing capability level highly rely on the tooling quality. So, study the knowledge of tooling development, get a robust system set up in the corporate, it is a must-be step for Chinese Auto related industrial in order to competing with world top level companies and match with the growing car production volume.In the first part of this thesis, study the characters of tooling development knowledge based on the theory of knowledge and knowledge management, also in this part, based on one company work flow of tooling development, identified all needed knowledge which belong to different category and then create a framework so to structure the knowledge as different level, meanwhile, some software applications been introduced and success key points also mentioned in the first part.In the second part of this thesis, different knowledge representation been introduced and based on the actual needs of one company’s tooling quote process,2 kind of knowledge representation-framed based and rule based knowledge representation been adopted to present tooling quote knowledge and discussed the implementation methods.In the third part of this thesis, focus on the expert knowledge which people call invisible knowledge, develop the representation method with the 6 sigma management concept, and then create a molding issue solving system with the approach of Case Based Reasoning.The result of this thesis could help engineers in tooling developing process with higher efficiency; avoid the people-relying condition which happed in the old developing process.
