【摘要】 提高工作流的重复利用程度,是快速建立工作流模型的关键。提出了基于配置的可复用工作流设计方法。该方法的基础是通过对工作流进行保留目标的多途径分解,以建立其非精确模型。在实际执行时,根据配置的范围与参数不同,采用相应的配置方法得到其精确模型。将工作流模型中结构相同的部分作为"复用元"以提高工作流的设计效率。讨论了从"重复有用性"、"复用粒度"以及"复用成本"等几个方面进行工作流可复用性综合评价的方法。最后给出了应用实例。更多还原

【Abstract】 workflow modeling. A methodology of configuration based reusable workflow design is proposed. The basis of this methodology is to build the inexact model of workflow by decomposing it into several parts based on multi-methods with object unchanged. According to the scopes and parameters, the exact model of workflow is obtained by using corresponding configuration methods when it is executed. In order to promote the efficiency of workflow design, the components with same structure in the workflow model are treated as reusable item. Some properties of reusable item, such as usage, granularity and cost of reuse, are used to synthetically evaluate the reusability of workflow. Lastly, a case of study is given.更多还原
