面向锻件产品开发的知识建模方法及应用

针对日前锻件产品开发的特点及存在的问题,规划了基于知识的锻件产品开发流程,并根据开发流程,结合开发知识的特点将知识划分为领域知识、实例知识和设计历史知识,提出了面向锻件产品开发的知识建模方法.本文采用规则/框架的综合表达方法对3种锻件产品开发知识进行组织建模,并利用面向对象方法将这3类知识模型集成构建了锻件产品开发知识集成模型.基于该建模方法和ASP.NET平台,采用面向对象语言C#,结合ORACLE数据库技术开发了锻件产品开发系统并得到了有效应用.

Knowledge modeling approach of product development for forged piece and its application

Aiming at the characteristic of product development for forged pieces and problems existing in the process of the product development,the knowledge-based product development flow for forged pieces was proposed;the development knowledge was classified into three types,i.e.domain knowledge,case knowledge and knowledge of design history,in combination with development flow and the characteristics of development knowledge;and then a knowledge modeling approach was presented.These three kinds of development knowledge were modeled by a comprehensive expression method of rules/framework.The three types of knowledge models were integrated to build an integrated model of product development knowledge for forged pieces by means of the object-oriented method.On the basis of the modeling approach and ASP.NET platform,the product development system of forged piece was developed with the object-oriented language of C# and database technology of ORACLE.
