摘　　要：传统的计算机辅助SDG-HAZOP是纯定性的分析与推理,它忽略了SDG图中节点之间的影响程度不同这一信息,因此它分析的结果往往过于冗繁。针对这个问题,文章提出了一种模糊SDG-HAZOP的新方法,这种方法的优势在于它把节点之间的相互影响用模糊矩阵的形式表示出来,采用矩阵的表示方法方便了计算机编程的实现,同时,将传统的推理方法转变成为一套模糊矩阵的运算方法,使SDG-HAZOP推理变为了一种半定量的推理,根据这些定量的信息,可以计算出各个相容通路的危险传播能力,最后可以把传播能力小的通路筛除出HAZOP分析结果,从而简化HAZOP分析报告。Traditional computer-aided SDG-HAZOP is a ignores the fact that the effect is different between different be too numerous.In order to solve this problem,a new kind paper.The advantage of this method is that the interactive kind of qualitative analysis and reasoning method,which nodes in a SDG graph.Because of that,its result can always of method of fuzzy SDG-HAZOP has been offered in this effect between nodes can be expressed in form of fuzzy matrlx,so that it can be much easier for computer programming.And this new method converts the traditional reasoning method into a method of fuzzy matrix calculating,which makes SDG-HAZOP changed into a kind of semi-quantitative method.Based on these quantitative information,the capability of hazard spreading of consistent paths can be calculated and those whose capability is weaker will be taken out from the result of HAZOP analysis,so that the HAZOP analysis report can be predigested.
