Abstract: An integrated creative theory framework is proposed in this paper‚and then a replacement-based creative approach is introduced based on this theory．The approach employs a hyper-graph rewriting system to organize intrinsic information of the system and to model creativity process．It takes an existing system rather than external requirements as the starting point‚and then an innovative structure involving a new system can be obtained by a sequence of formal operations on the initial hyper-graph structure of the system．
