基于知识的集成制造柔性仿真系统

KNOWLEDGE-BASED INTEGRATED MANUFACTURINGFLEXIBLE SIMULATION SYSTEM

利用ＣＩＭＯＳＡ体系结构中ＦＢＳ模型、实体类库、过程知识库和数据库建立了ＣＩＭ系统的访真模型知识库，并通过面向对象框架语言对其进行表达，由推理机从过程规则集中推理产生仿真模型的行为。由于各种类库的使用，使得该系统具有柔性，故称为基于知识的集成制造柔性仿真系统。功能部分／ｍｅｍｂｅｒｓｌｏｔ：１０ｆｒｏｍＥＦ；／＊输入输出槽＊／ｉｎｈｅｒｉｔａｎｏｅ：ｏｖｅｒｒｉｄｅ；／＊继承属性＊／ｖａｌｕｅｃａＩｓｓ：ｓｔｒｉｎｇ；／＊值类型＊／ｖａｌｕｅｓ：ＦｕｎｃｔｉｏｎＩｎｐｕｔ；／＊值为功能输入＊／ｅｎｄｓｌｏｔ；／行为部分／ｍｅｍｂｅｒｓｌｏｔ：ＥＶｔｙｐｅｆｒｏｍＥＦ；ｖａｌｕｅｃｌａｓＳ：Ｓｔｒｉｎｇ；ｖａｌｕｅｓ：ＥｘｔｅｒｎａＩＥＶ；／＊外部事件＊／／结构部分／ｍｅｍｂｅｒｓｌｏｔ：ＣｏｍＰｒｉｓｅｓｆｒｏｍＥＦ；ｖａｌｕｅｃｌａｓｓ：ＥＡ；ｖａｌｕｅｓ：ＥＡ２１１，ＥＡ２１２，…，ＥＡ２１９；ｍｅｍｂｅｒｓｌｏｔ：Ｗｈｅｒｅ．ｕｓｅｄｆｒｃｏＥＦ；ｖａｌｕｅｃｌａｓｓ：ＤＰ；ｖａｌｕｅＳ：ＤＰ２；／过程知识／ｍｅｍｂｅｒｓｌｏｔ：ＡｌｇｏｒｉｔｈｍｆｒｏｍＥＦ；ｉｎｈｅｒｉｔａｎｃｅ：ｍｅｔｈｏｄ；ｖ?

The simulation model knowledge baseof CIM consists of five parts, FBS model-of CIMOSA system architecture, entity class libraryiprocedural knowledge base,database andinference engine. This knowledge based simulation model is represented by objectorientedframe language and its behaviour is generated by inference engine reasoning procedural rulesets. Because of using various class libraries Which make this system flexible. it is calleda knowledge-based integrated manufacturing flexible simulation system.
