摘要
现有工作流生成研究大多只关注过程定义的自动创建,却很少讨论相应的流程执行机制,因而不仅缺乏对工作流动态生成的支持,也存在活动资源绑定过早、缺少人工活动支持等不足。针对该问题,结合基于流程模式的工作流生成规划,提出一个流程动态执行机制。它通过抽象活动即时规划实现工作流运行时细化;通过参与者服务化方法来实现活动资源的即时绑定执行。减少运行时异常的同时,也提供了对人工与自动活动的统一支持。
Current workflow generation researches often focus on automatic process construction and rarely discuss related execution mechanism. Hence, they often lack of the support for workflow dynamic generation, activity just-in-time resource binding and manual activities. Based on pattern-oriented workflow generation planning, a synthesis execution mechanism in workflow generation was proposed It provides an abstract activity planning approach to support workflow runtime refinement and uses participant servicization approach to facilitate activity-resource just-in-time binding. It minimizes possible runtime exceptions and provides a unified support for manual and automated activities.
