To support data mining in case bases , the thesis proposes a case representation based on traditional object - oriented representation . a case is represented by a weighted feather vector 為了支持對案例庫的挖掘,本文在面向對象的案例表示的基礎上,提出了一種基于加權特征矢量的案例表示方法。
An object - oriented representation method of fault cases is proposed using object - oriented ideas . the hierarchy model of fault case has been built by using the concept of abstract cases 在故障案例的表示方法上,提出了一種面向對象的故障案例表示方法,并引入抽象案例的概念,建立了故障案例對象的層次結構模型。
After expounding the actual and development trend of process planning knowledge management , combining with the basic conception of it , this paper presents a classification and hierarchy model for supervising knowledge , and sets up a process planning resource knowledge base using the model ; the process planning knowledge is expressed with intelligent object representation which is synthesized rule , framework and object - oriented representation ; process planning knowledge is showed by process planning tree using the idea of intelligent object representation ; in the end , the algorithm of the inconsistency of knowledge base and integrality are also given 本文在闡述了工藝知識管理系統的現狀及發展趨勢后,結合工藝知識管理的基本概念,提出了一種分類層次模型以組織和管理工藝知識,并據此建立工藝資源知識庫;采用產生式規則、框架表示和面向對象三者相結合的方法? ?智能對象表示法對工藝知識進行表示;并利用智能對象表示法的思想將工藝知識通過工藝知識樹的形式顯示出來;最后給出了工藝知識庫不一致檢測和完備性檢查算法。
Abstract : it advances an idea that transaction is the basic unit of product design activities , and sets up transaction model as an object - oriented representation for design goal , personnel , document objects , resources , constraints and statas . the model is integrated for product and process . it introduces the prerelease mechanism of collaborative design and triggering mechanism of related transaction also 文摘:提出了以設計事務作為產品設計活動基本單元的思想,采用面向對象的方法建立了設計事務模型,描述了產品設計的目標、組織、文檔對象、資源、約束、狀態等特征信息,建立了支持協同設計的設計事務預發布機制和相關設計事務觸發機制,實現了產品和過程的集成建模。
