工作流管理系统支持业务流程，并由其模型驱动。这些模型涵盖了不同的视角，包括控制流、资源和数据视角.本文着重从资源的角度，即，系统根据组织结构和人员的能力/资格分配工作的方式。当代工作流管理系统提供了各种各样的机制来支持资源观点。由于资源的角度是必不可少的适用性，这样的系统，重要的是要更好地了解机制和它们的相互作用。我们的目标不是评估和比较不同的系统做什么，而是理解它们是如何做的。首先，我们提供了一个基本模型，可以被看作是现有工作流管理系统的“最大公分母”。然后，该模型扩展到三个特定的系统（Staffware，FileNet和FLOWer）。此外，我们将展示如何更先进的工作分配机制，称为资源模式，可以建模和分析。
Work ow management systems support business processes and are driven by their models. These models cover different perspectives including the control- ow, resource, and data perspectives. This paper focuses on the resource perspective, i.e., the way the system distributes work based on the structure of the organization and capabilities/qualifications of people. Contemporary work ow management systems offer a wide variety of mechanisms to support the resource perspective. Because the resource perspective is essential for the applicability of such systems, it is important to better understand the mechanisms and their interactions. Our goal is not to evaluate and compare what different systems do, but to understand how they do it. We use Colored Petri Nets (CPNs) to model work distribution mechanisms. First, we provide a basic model that can be seen as the \greatest common denominator" of existing work ow management systems. This model is then extended for three specific systems (Staffware, FileNet, and FLOWer). Moreover, we show how more advanced work distribution mechanisms, referred to as resource patterns, can be modelled and analyzed.
