使业务流程模型适应环境的变化是企业保持竞争力的重要任务.建模期间无法预知的变化是一类常见且困难的挑战,需在运行时根据流程实例和上下文动态绑定.前人的工作(如Worklet)可将任务延迟到运行时绑定或建模到子流程.但是,尚无有效方法处理流程中这些任务延迟绑定到的子流程间的依赖关系.提出一种业务流程依赖建模方法,设计了一个基于WSCoordination的协同规范使处理任务延迟绑定的Web服务在前述依赖关系下协同工作,并通过扩展YAWL和Worklet实现的原型系统证实所提出机制的可行性.该机制是一种兼顾流程运行时灵活性和流程约束的业务流程管理方法. Making business process models adapt to changing environments is an important part of your organization’s ability to stay competitive. Unpredictable changes during modeling are a common and difficult challenge that need to be dynamically bound at runtime to process instances and contexts. (Such as Worklets) can delay tasks to run-time binding or modeling to subprocesses However, there is no efficient way to handle these tasks in the process to delay the dependencies between the subprocesses to which the bindings are bound.We propose a business process dependent build Model, a WSCoordination-based collaborative specification is designed to make the Web service which delays the processing of tasks work together under the aforementioned dependencies and the feasibility of the proposed mechanism is verified by extending the prototype system implemented by YAWL and Worklet. A business process management approach that takes into account the flexibility of the process runtime and the process constraints.
