consistency constraints 中文意思是什麼

consistency constraints 解釋
一致性約束
  • consistency : n. 1. 無矛盾，相容（性）；始終一貫；穩定（性）；（言行）一致，（色調）調和。2. 堅強，堅定，堅固，結實；堅實度。3. 濃度，稠度；黏度。
  • constraints : 變動極限
  1. Verifying the soundness of the uml statecharts model can be translated into the verification of the soundness of the global reachable state transition diagram, and the algorithms verifying the soundness and the properties of semantic - related are given. at the aspect of verifying the consistency of temporal constraints of workflow, the time events are added into the uml statecharts, then the rules translating the extended uml statecharts into timed automata are given. the upper constraints ( the most time interval between two tasks ), lower constraints ( the least time interval between two tasks ) and deadline constraints are defined by tctl. the consistency of these constraints in build time, instantiation time and run - time are defined respectively

    在驗證工作流時序約束一致性方面，在uml狀態圖中加入了時間事件，給出了將擴展后的uml狀態圖轉化為時間自動機的規則，用時間計算樹邏輯定義了兩個任務間的最大、最小時間間隔（上、下界約束）和工作流的最終期限約束，並給出了這三類約束分別在創建階段、實例化階段和運行階段的一致性定義，通過alur的演算法對時序約束一致性進行驗證。
  2. In recent years, many researches have been devoted to designing appropriate concurrency control algorithms for rtdbss, which need not only satisfy consistency requirements but also meet transaction timing constraints as much as possible to minimize the percentage of late transactions

    近年來很多研究人員致力於設計適合實時數據庫系統的並發控制演算法。實時事務並發控制演算法不但需要保證數據庫的一致性，同時還要盡量滿足實時事務的截止期來降低系統的錯失率。
  3. Consistency - every transaction must preserve the integrity constraints - the declared consistency rules - of the database

    一致性每個事務必須保持數據庫的完整性約束聲明的一致性規則。
  4. The consistency constraints provide a way to decouple the disciplines and make the parallel subsystem optimization possible

    通過引進一致性約束條件，實現學科之間的解耦和并行優化。
  5. Then, consistency constraints can by specified and validated using the language and the tools of the semantic domain

    方法不但簡單、直觀，而且不需要增加額外的信息，並且可以利用現有的語法分析工具。
  6. In this approach, design tasks are decomposed into a system - level optimization and subsystem - level optimizations. the task of each subsystem optimization is to find the local variables to minimize or maximize objectives, subject to its local design constraints. the task of the system - level optimization is to find global ( or shared ) and auxiliary variables to optimize the system performances, and satisfy the consistency constraints

    這種方法將優化流程分為系統級優化和單學科優化兩個層次:系統級優化的任務是通過調整共享設計變量和輔助設計變量，在滿足一致性約束條件下，使系統目標最優;子系統的任務是調整局部設計變量，在滿足本學科的設計要求條件下，使子系統的目標最優。
  7. If a new constraint is incompatible with previous ones, then the whole system becomes inconsistent. therefore, it is very important to judge the consistency and redundancy of information, hi this chapter, we propose the linear and non - linear programming models to check the consistency and redundancy of information and give an approach to make system transform from inconsistency to consistency by abbreviating the incompatible constraints

    如果一個新的約束條件是冗餘的，那麼，它對改進決策結果起不到任何作用，如果一個新的約束條件與以前的信息不相容，那麼就會造成整個系統不一致，因此，判斷信息的一致性和冗餘性有非常重要的意義。
  8. Although congestion control is required by all applications to ensure network safety, different applications have various constraints in speed, quality and consistency of data delivery

    盡管所有的組播應用都要求通過擁塞控制機制來保證網路的安全性，但是不同的應用在數據傳輸的速度，質量和一致性上有不同的要求。
