| 摘 要： | 随着服务组合和云计算的发展，基于服务的数据感知过程得到了越来越多的关注。为检测和解决数据感知过程的众多变种之间的差异，过程一致性的研究就显得很有意义。于是，一种数值化地度量数据感知过程行为一致性的方法被提出。该方法以活动间的三种约束关系（偏序关系、互斥关系和独立关系）为基础，将事件日志中活动执行频率作为权重，从而能够从静态和动态两个层面分析数据感知过程之间的一致性。实现了能够基于事件日志数值化地度量业务流程执行语言（business process execution language，BPEL）过程之间一致性的原型工具。通过案例分析，验证了该方法的可行性和有效性。因此，提出的方法能够很好地解决数据感知过程之间一致性度量的问题。 |

| Abstract： | The development of service composition and cloud computing has increased the attention on service-based data-aware processes. The consistency measurement between increasing variants of data-aware processes is significant to the detection of differences and integration of variants. Then, an approach is provided to quantitatively measure consistency of data-aware processes. This approach is based on three constraint relations between activities (partial order, mutual-exclusion and independence) and the weight of probability of activity occurrence in event logs. It can analyze consistency of data-aware processes from the two aspects of dynamic and static. A proof-on-concept tool is implemented to automatically calculate consistency of business process execution language (BPEL) processes based on event logs. Case study verifies feasibility and effectiveness of the proposed approach. Hence, the approach can well solve the problem of consistency measurement of data-aware processes. |
