针对船舶电力系统可靠性建模难的问题,提出了一种适用于电网结构可靠性估计的自适应模糊Petri网模型。该模型首先给出了模糊神经Petri网定义及其适用于可靠性建模的引发规则,并在此基础上提出一种学习算法。该算法既可以表示和处理模糊产生式规则的知识库系统,又具有学习能力。最后,建立了船舶电力系统可靠性评估模型,并通过定性分析和定量计算,验证了该模型和算法的有效性。
According to the practical conditions of shipboard power system,an adaptive fuzzy Petri-net model was presented for evaluating the reliability of shipboard power system.The model refered to the definition of the fuzzy Petri net and the rules suitable for reliability of modeling.Then a learning algorithm was put forward which could handle the knowledge-based system of fuzzy productive rules and possess the capability of learning.Finally the model for evaluating the reliability of shipboard power system was established.Through the qualitative analysis and quantitative calculation,the results show that the model is effective and reasonable.
