基于突变理论的维修保障系统效能评估研究

基于突变理论，采用突变评价法对空军通信装备维修保障系统效能评估的方法进行了研究，并与层次分析法的结果进行了比较，结论基本一致。为维修保障系统的效能评估寻求出一种新的方法，其评估结果可为决策提供定量依据。

Study of Effectiveness Evaluation of Maintenance Support System Based on Catastrophe Theory

From the point of view of the optimization in fuzzy control, the idea of variable domain and the concept of flex factor are discussed. At the same time the preponderance of variable domain and the relationship between the quantization factor, the proportional factor and the flex factor are explained. In addition, the method of selecting the two flex factors is analyzed in detail. Another new intelligence control means - fuzzy logic adjusting PID online based on variable domain on self - adaptation is realized by putting the idea of variable domain into fuzzy PID. The research is based on some complicated nonlinear system, and the result of simulation is predominant.
