Abstract: The non-certain choice and parallel pattern is ubiquitous in the real business practices，the execution pattern is chosen based on case character and run-time environment，which can be parallel，exclusive or interleaved executive pattern，but it is hard to be realized directly and effectively in many situations which makes it seldom be supported.In nature，the method of process modeling based on synchronize-manager separates the process management tasks from its execution tasks，defines the stable and variable parts of the process；this helps in flexible constructing of the model.Different management actions and model structure resemble can be used to create the non-certain choice and parallel pattern.Analysis of real cases shows that it is easy to construct the non-certain choice and parallel pattern by using synchronize-management，semantic description is more accurate，model is simpler and more effective and with better ubiquitous.

Key words: synchronize－manager, non-certain choice and parallel pattern, workflow pattern

摘要： 非确定选择平行模式在实际业务流程中非常普遍，模式的执行行为根据案例属性和运行环境来动态选择，可以是平行、选择或者交替执行路由的模式，但是在许多情况下很难直接、有效地实现，很少有系统支持这种模式。基于同步管理器的流程建模方法从本质上将流程的管理任务和执行任务分离，明确了流程中稳定和可变的部分，这种分离有利于构建灵活的流程模型.不同的管理行为和模型结构重组可以构建非确定选择平行模式。实例分析表明基于同步管理器很容易建模非确定选择平行模式，而且语义表述更加精确，模型简单、有效，并具有较强的通用性。
