  1. Asn. 1 is a data definition language which allows formal definitions of information structures to be expressed in a manner which is independent of any implementation constraints

    抽象語法符號asn . 1是一種資料定義語言，透過將資訊結構的定義正規化，使資料結構在任何發展環境之下都能用相同的表示方法來表示。
  2. In the light of the method of top - down, the author put forward the concept of product function structure tree, which was used to express the product ' s function structure during the conceptual design. based on it, the product structure was expressedthe paper studies the definition of the function model which supports the method of top - down design, and the expression of function model based on binary - tree was also put forward in the thesis. for the abstract description of parts in the assembly level and the integration with other systems during the whole life circle of the products, the concept of assembly model was presented, the definiton, classfication and expresstion method of assembly feature was studied in this thesis. the representation of assembly relationship and data structure of the assembly model based on diagram was further studied. for the constraints transfer between function model and assembly model, an hierarchical component model is presented. an arithmetic of the change of assembly relationship when assembly model changing was also studied. fmally, a system named fb - tpms, which using object oriented programming technology and pro / toolkit, was developed

    為了支持在裝配層次上的零件的抽象建模，提出了骨架模型的概念，並討論了裝配模型的建立方法。根據前述裝配模型有關研究，探討了從功能模型到裝配模型以及從上一級裝配模型到下一級裝配模型的數據和約束傳遞問題，並用層次化單元裝配模型得以解決，同時提出了裝配模型變動時引起的裝配關系的變化的有關演算法。在論文的最後部分用用面向對象的程序設計方法，結合課題要求，研究了支持自頂向下設計方法的裝配建模系統fb - tpms 。

  4. In spite of different methods to a fuzzy optimal solution to the two classes of fuzzy linear programming, these methods have similar ideas : first is to fuzzify the objective function and constraints, i. e., to display the definition of fuzzy membership function. second is to transfer the fuzzy linear programming into one general linear programming, based on the fuzzy decision, then we can obtain the fuzzy optimal solution by solving this linear programming

    雖然求這兩類模糊線性規劃的模糊最優解的方法並不相同，但其思想具有相似性：首先是把目標函數或約束條件模糊化，給出他們的隸屬函數的定義；然後給出模糊判決，在此基礎上，規劃最終都可化為求一個普通規劃的解，這個解可看成模糊線性規劃的模糊最優解。
  5. Settings and constraints on members of a system definition

    系統定義中成員的設置和約束。
  6. Security constraints are consistent by modifying security constraint definition, and an effective classification assignment algorithm is given in this paper. we analyze the problem of inference channel and give solution to solve the problem during database analysis and design period. by analyzing the problems resulting from extending single - level transactions to multilevel transactions, we also give a multilevel secure transaction schedule algorithm based multiversion snapshot graph

    本文提出採用主從結構表的方法對blp模型加以改造，使得改造后的blp模型具有較高的可用性和安全性；通過修改安全約束的定義，使得安全約束之間始終是協調的，並給出一種高效的密級分配演算法；討論了推理通道問題，給出了在數據庫分析、設計等階段可以採用的對策；分析了事務從傳統的單級擴展到多級面臨的眾多難題，給出了一種基於多版本串列化圖的事務調度演算法；根據上述理論，開發了一個多級安全數據庫管理系統的原型系統。
  7. Inplementation of the above in a prototype system named cacds in the first part of the thesis the general contents of computer aieded conceptual design and its status quo is inrtoduced. detailed definition of component feature model ( cfm ) and its relative operations are described in chapter 2. in chapter 3 we invited " " component feature space " as the key element in layout design, and a new constraints driven layout creation methodology, which is based on graph theory and human - computer cooperation, is discussed

    本文以國家863計劃項目? ? 「面向產品創新的計算機輔助概念設計技術的研究」為背景，以產品信息模型和求解方法為著眼點展開研究，主要貢獻在於： （ 1 ）拓展了組件特徵模型，使其可以支持概念早期設計階段的信息表達和推理； （ 2 ）提出了一種基於約束驅動，結合約束圖與人機合作的布局設計求解方法； （ 3 ）在cacd原型系統中，對上述兩點進行了實踐。
  8. Drdl can be used to describe timing constraints event and supports dynamic change of high level event definition. since its syntax is similar to c language, users can master it easily. by iterating directory event embedded in drdl file system security monitoring and performance monitoring can be integrated into the event monitoring framework

    通用的動態規則描述語言drdl能描述事件的時問約束，支持高層事件定義的動態改變；它採用類似於c語言的語法以便於用戶學習；通過drdl中內置的「遍歷目錄」事件，可以靈活定義規則，將文件系統的安全性檢測與性能監控統一到事件監控框架下。
