探索和理解大型业务流程模型是业务流程管理背景下的重要任务。近年来，已经提出了几种用于业务流程抽象的技术。自动抽象技术被设计用于验证流程模型的正确性和一致性，并为业务流程分析师提供定制的流程视图。然而，以目标为中心且基于语义的方法来生成有目的的业务流程抽象仍然是一个悬而未决的问题。我们提出了一种针对特定抽象目标的流程抽象配置方法，该特定抽象目标表示为对具体和抽象流程以及流程转换运算符之间的对应关系的约束。我们的框架超越了简单的结构聚合，并利用特定于领域的属性、分类法、单体名和流程标准来生成抽象流程模型的层次结构。我们概述了基于约束的框架，描述了基于重写的抽象机制如何嵌入指导抽象搜索的一致性标准，并展示了如何利用行为一致性的概念来获得符合行为过程继承标准的抽象。
Exploring and understanding large business process models are important tasks in the context of business process management. In recent years, several techniques have been proposed for the abstraction of business processes. Automated abstraction techniques have been devised for verifying correctness and consistency of process models and for providing customised process views for business process analysts. Yet a goal-focused and semantic-based approach to generate purposeful abstraction of business processes is an open issue. We propose an approach for configuration of process abstractions with respect to a specific abstraction goal expressed as constraints on the correspondence relation between concrete and abstract process and process transformation operators. Our framework goes beyond simple structural aggregation and leverages domain-specific properties, taxonomies, meronymy, and flow criteria to generate a hierarchy of abstract process models. We outline the constraint-based framework, describe how rewriting-based abstraction mechanisms are embedded with consistency criteria guiding the search for abstractions, and show how notions of behaviour consistency can be utilised to obtain abstractions that conform to behavioural process inheritance criteria.
