Abstract
The 20 workflow patterns proposed by van der Aalst et al. provide a comprehensive benchmark for comparing process modelling languages. In this article, we discuss workflow pattern support of Event-Driven Process Chains (EPCs). Building on this analysis, we propose three extensions to EPCs in order to provide for workflow pattern support. These are the introduction of the so-called empty connector; inclusion of multiple instantiation concepts; and a cancellation construct. As both the latter are inspired by YAWL, we refer to this new class of EPCs as Yet Another Event-driven Process Chain (yEPC). Furthermore, we sketch how a transformation to YAWL can be used to specify the semantics of yEPCs.
van der Aalst等人提出的20种工作流模式为比较流程建模语言提供了一个全面的基准。在本文中，我们将讨论事件驱动流程链(epc)的工作流模式支持。在此分析的基础上，我们建议对epc进行三种扩展，以提供工作流模式支持。这些都是介绍所谓的空连接器;包含多个实例化概念;还有一个消去结构。由于后者都受到了YAWL的启发，我们将这类新的epc称为另一个事件驱动流程链(yEPC)。此外，我们概述了如何使用到YAWL的转换来指定yepc的语义。
