摘要

针对工作流过程演变时过程实例的跃迁策略不易确定的问题

提出了一种表达灵活的工作流过程模型

并将过程模型的更改转化成若干更改域

更改域包含三类元更改操作.为了确定过程实例能否平滑地迁移至新的过程模型

又提出了通过更改域边缘查找更改点的方法.比较更改点位置与当前过程实例状态

确定过程演变策略

并给出过程演变算法

从而实现了过程实例迁移.实际应用表明

所提算法可自动导出工作流过程演变策略

并实现过程实例的批量跃迁.

Abstract

Aiming at the problem that the migrating strategies of process instances are difficult to determine in process evolution

a workflow process model with flexible expressiveness was proposed

and the change of it is transformed into some change domains which contain three kinds of meta-change operations. In order to determine whether a process instances can be migrated to a new process model smoothly

an approach to find out all points of change(PoC)through confining the change domains was also proposed. The positions of PoCs were compared to the current states of process instances in order to decide the strategies of process evolution

and the process evolution algorithm was given and the migration of process instances was realized. The practical applications show that the proposed algorithm can deduce the process evolution strategies of workflow automatically

and the process instances migration can be carried out in batches.
