摘　　要：针对现有流程相似性度量中存在的不同程度的缺陷,为有效度量流程的相似性,提出一种基于业务流程描述框架(business process description framework,BPDF)的流程相似性度量方法。基于流程注册元模型框架(MFI-5)构建BPDF,定义流程相似性特征集(similarity feature set,SFS);利用SFS对流程模型进行标识与量化,考虑每个特征中的相似性以获取两个流程间的相似性。该方法涉及的特征符合实际应用中流程具有的核心特征。实验结果表明,该方法在实际应用中能有效度量流程间的相似性。Aiming at the defects of existing process similarity measurement in different degrees,an approach was presented based on business process description framework(BPDF)to measure process similarity effectively.Based on MFI-5,BPDF was constructed,and similarity feature set(SFS)of the process was defined so that the typical features of the business process were embodied accurately.SFS was used to identify and quantify process model.The similarity in each feature was considered to obtain the similarity between two processes.The features involved in the method accord with the core features of the process in practical application.Experimental results show that the proposed approach is effective for the similarity measure of the processes in practical applications.
