一种基于扩展任务结构的工作流实例迁移方法(英文)

A Workflow Instance Migration Approach Based on the Extended-Task-Structures

工作流实例迁移是工作流演化研究中典型而重要的问题.在基于扩展任务结构的工作流定义的基础上,提出了适用于一般动态变化处理的实例迁移规则、条件和算法.与同类研究工作比较,该方法在适用范围、通用性、正确性和可实现能力等方面具有一定的先进性.

Workflow instance migration is a typical and important problem in the research of workflow evolution. Underlying the definitions of the extended-task-structures based workflow, some rules, conditions and an algorithm for workflow instance migration are presented, which are suited to generic dynamic changes. By the comparisons with other similar research works, the advantages of the approach in terms of applicability, universality, correctness and practicality are illustrated.
