| 中文摘要: |
| 过程具有长生命周期、分布式结构、异构等特性.为适应不可预料的环境变化,过程还需要不断地演化.提出一种过程实例的演化方法以控制对过程实例的改变.它可以检查并保证演化前后的过程实例具备"基于目标的行为一致性",从而避免用户对过程的盲目修改.目标作为行为一致的标准,需要分析演化后的过程实例来保证它可以完成目标.通过用Büchi自动机描述过程实例和其目标的语义,一个过程实例是否能够完成其目标是可判定的. |
| 英文摘要: |
| Process is long-lived, distributed, heterogeneous, and always evolutive to cope with unforeseen environment. In this paper, an approach for process instance evolution is proposed, which is a formal approach that focuses on ensuring the "goal-based behavior consistency" between the evolved process instance and the original instance in order to avoid ad-hoc change of process model. The goal is regarded as the criterion of behavior consistency, so evolved process instance needs to be analyzed in formal methods to ensure that it can still achieve its goals. Through specifying the semantics of process model and goals as Büchi automaton, whether an executing process instance can achieve its goals or not is decided. |
