反演计算技术及其在动态工作流管理中的应用

Computational Reflection and Its Application in Adaptive Workflow Management

反演计算技术自诞生以来,对若干信息技术领域分支的发展带来了深远的影响,在增强灵活性方面展示出巨大潜力.对工作流技术来说,灵活性问题正是应该具备而却没有得到很好解决的问题.首先介绍反演计算的基本概念以及面向对象反演计算的模型,然后介绍反演计算目前的一些典型应用.最后,结合作者目前的工作,给出反演计算在动态工作流中的应用模型,并设计实现了原型系统,经过初步验证,该模型和原型系统能够对工作流的灵活性问题提供良好的支持.

Since the birth of computational reflection, it has influenced many branches of information technology, showing huge potentials in flexibility enhancement. For workflow management technology, flexibility is an indispensable feature that has not been satisfactorily acquired. In the paper, the fundamental ideas of computational reflection and models of object-oriented reflection are introduced first. Then, some typical applications of reflection are presented. Finally, a reflective model used in the adaptive workflow system is given, and the running mechanism for enhancing application flexibility is described.
