摘要: 目前的流程模型行为相似性算法有着不同程度的缺陷,为此首次提出任务最短跟随距离矩阵的概念,以很好地体现流程模型的行为特征,并给出了基于Petri网完全有限前缀的高效计算方法。基于该矩阵提出的行为相似性算法能完整支持流程模型各类结构。与现有算法的对比表明,该算法更符合流程模型行为相似性算法应该具有的各项性质。

Abstract: Aiming at the various degree of defects existed in behavioral similarity algorithm between process models,the concept of Shortest Succession Distance between Tasks (SSDT) matrix was introduced,which could represent the behavioral characteristics of process models well.Meanwhile,an efficient computing method based on complete finite prefix of Petri nets was proposed.The behavioral similarity algorithm based on SSDT matrix was put forward to support all possible complex structures of process models.Compared with current approaches,the proposed algorithm could meet all the prospective properties better.

Key words: process model, behavioral similarity, shortest succession distance between tasks matrix, algorithms
