Modeling of work systems occurs for all sorts of reasons. Requirements need to be expressed. A pre-existing situation may need to be charted and analyzed. Early design decisions may be captured using architecture principles. Detailed design may be worked out. We all regard these activities as essentially being forms of modeling. In the work systems modeling library, we consider work system engineering from a modeling perspective. In the field of work system engineering, a whole plethora of modeling methods is available to system engineers and architects. Each of these methods can be used to model some (aspects) of a domain related to an existing and/or a planned work system. The aspects may refer to requirements, architecture, design, processing, data, etc, etc. In other words, these methodes are essentially all intended to model different aspects of work systems and/or their context. The aim of the work systems modeling library (WSML) is to bring together methodical knowledge concerning the modeling of work systems.

工作系统建模库

出于各种原因对工作系统进行建模。需要表达需求。可能需要将先前存在的情况绘制成图表并进行分析。可以使用体系结构原理来捕获早期的设计决策。可以设计出详细的设计。我们都认为这些活动实质上是建模的形式。在工作系统建模库中，我们从建模角度考虑工作系统工程。在工作系统工程领域，系统工程师和架构师可以使用大量的建模方法。这些方法中的每一个都可以用于对与现有和/或计划的工作系统相关的某个领域（方面）进行建模。这些方面可以指需求，架构，设计，处理，数据等，等等。换句话说，这些方法本质上都旨在对工作系统和/或其上下文的不同方面进行建模。工作系统建模库（WSML）的目的是将有关工作系统建模的方法知识汇集在一起​​。
