流程模型，即使用资源和工件执行活动的代理的协调的正式定义，可以帮助理解它所建模的实际流程。此外，对模型的分析可以对实际过程提出改进建议。然而，复杂的现实世界流程表现出大量的变化，这些变化可能很难或不可能用单个流程模型来表示。在给定建模符号的限制下，这样的过程通常可以通过一系列模型更好地建模。本文提出了一种对其中一些过程族进行形式化表征的方法。确定了过程变化的各种需求，并就如何使用不同的方法来满足其中一些需求提出了建议。一些对可变性的不同需求到满足这些需求的方法的映射作为案例研究提出。
A process model, namely a formal definition of the coordination of agents performing activities using resources and artifacts, can aid understanding of the real-world process it models. Moreover, analysis of the model can suggest improvements to the real-world process. Complex real-world processes, however, exhibit considerable amounts of variation that can be difficult or impossible to represent with a single process model. Such processes can often be modeled better, within the restrictions of a given modeling notation, by a family of models. This paper presents an approach to the formal characterization of some of these process families. A variety of needs for process variation are identified, and suggestions are made about how to meet some of these needs using different approaches. Some mappings of different needs for variability to approaches for meeting them are presented as case studies.
