絕對補集
英文
absolute complement of set-
With the development of the network and the multi - processor system, the research, simulation and the impemeni of the system - level fault diagnosis which is the very important means to increase the reliability of the system, are becoming more and more important. on the system - leve1 fault diagnosis, based on the group theory of system - level fault diagnosis that has been put forward by pro f zhang, the paper constructs newly the theory bases, improves on the matrix method, reinforces and consummates group arithmetic of all kinds of test mode, for the first time, analyses and discusses the equation solution of all kinds of models, so al1 the consistent fault patterns ( cfp ) could be found, straightly and high efficiently, even if the sufficient and necessary condition of t - diagnosable is dissatisfied and the complexity of system - level fault diagnosis is greatly decreased, especialy in strong t - diagnosabl6 system. last the simulation system ' s function has been extended and the application hotspot and the development trend have been disscussed
本人在張大方教授等人提出的基於集團的系統級故障診斷的理論基礎上，重新構建了系統級故障診斷的理論基礎，定義了系統級故障診斷測試模型的三值表示；改進了系統級故障診斷的矩陣方法，重新定義了測試矩陣、鄰接矩陣、結點對、結點對的相連運算、極大準集團和斜加矩陣，由此能直觀、簡便地生成集團和極大獨立點集；補充和完善了各類測試模型的系統級故障診斷的集團演算法，通過定義集團測試邊和絕對故障集，簡化了集團診斷圖，由此能較易地找到所有的相容故障模式，即使不滿足t -可診斷性，大大減少了系統級故障診斷的復雜度，尤其是對強t -可診斷系統；首次分析探討了各類測試模型的方程解決，由此從另一角度能系統地、高效率地求出所有的相容故障模式（ cfp ） ：擴充了系統級故障診斷模擬系統的功能，快速、直觀和隨機地模擬實驗運行環境，進行清晰和正確的診斷，同時提供大量的實驗數據用於理論研究，優化演算法和設計。Conventional iec three ratio method and new iec ratio criterion are reduced according to the method of decision table in rough set theory respectively, simplified diagnosis rules are proposed. besides being identical with original iec method, the codes of conventional iec three ratio method are increased and bounds of new iec ratio criterion are augment by using this method, codes imperfectness of conventional iec three ratio method and code name absence of new iec ratio criterion are improved to some extent, scarcity of codes in conventional iec three ratio method is offseted, absolutization of sort and boundary in new iec ratio criterion is overcomed. this is important in practice for its flexibility and enhanced error tolerances
應用粗糙集理論中的決策表化簡的方法分別對常規iec三比值診斷表和iec新導則診斷表進行了化簡，得到了簡化的診斷規則，它們不但具有與常規iec三比值法和iec新導則完全相同的診斷分類能力，而且擴充了常規iec三比值表的編碼范圍和iec新導則的診斷范圍，在一定程度上改善了常規iec三比值表編碼缺損和iec新導則無對應代號的問題，彌補了常規iec三比值法編碼的不足，克服了iec新導則分類及邊界的絕對化，使得iec診斷法在實際診斷中更具靈活性、實用性和容錯性，提高了故障診斷能力。
