摘要
迁移工作流的体系结构具有无中心性、动态性、松耦合等特征,如何在部分可观测的环境下保证迁移工作流运行时不偏离全局目标是其中的技术难题之一。基于目标关联度的决策思想,从对用户的服务导航的角度对此问题进行了探讨,提出一种部分可观测环境下的目标驱动服务导航机制。该机制建立一种目标关联策略描述规范,采用基于业务熟人推介的导航索实现方法,并给出一个目标驱动的服务导航算法。初步实践表明,上述机制为开发迁移工作流平台提供了有效支持。
Migrating workflow has the non-center, dynamic, and loose coupling architecture. How to ensure the correctness of migrating workflows in the partially observe environment is one of the hard technique problems in this field. Based on the idea of goal relation, this paper proposed a goal-driven mechanism for services navigation to solve the problem from the aspect of service navigation. Firstly, proposed goal relation policy to express observable environments, secondly, gave a navigation cable formation based on business acquaintances and a goal-driven algorithm for services navigation. Some development examples show that this mechanism can support the development of the migrating workflows effectively.
