Abstract: Expert should firstly construct the model of CD in application.It is necessary to construct the model of CD（MCD） of CS.However，it is difficult to directly construct.It is valuable to study how to make a constructed MCD really reflect fact and reduce difference.To overcome the difficulty of the modeling of CDCS，a composing method for CCD is advised and verified by an example in this paper.This method can synthesize causality diagrams constructed by the same expert or by different experts respectively through multifold methods.The research shows that the composing modeling method for CD of CS is so feasible and effective that it simplifies the modeling of CD and offers an effective approach to tackling expert knowledge with CD.
