摘要
分析工作流挖掘中存在的隐含库所和隐含迁移等问题。针对a算法处理隐含问题时存在的不足，提出a＋＊算法。该算法对隐含任务另做标记，利用任务间的相互依赖关系得出过程模型。通过仿真工具CPN Tools生成文件，利用ProM和a＋＊算法挖掘日志，仿真结果证明了该算法的有效性。
This paper analyzes the problems of implicit places and implicit transitions. In view of the shortage of a algoritm to resolve the implicit problems, a＋＊ algorithm is presented. In this algorithm, the implicit tasks are marked in another style, the model are constructed by the dependency of the tasks. It uses CPN Tools to general log files and mines the logs by ProM and a＋＊ algorithm. The simulation results validate the efficiency of the algorithm.
