The BPMN standard has a huge uptake in modelling business processes within the same organisation or collaborations involving multiple interacting participants. It is widely accepted by the Business Process Management community that a solid formal framework for the notation can help designers to properly understand their BPMN models as well as to state and verify model properties. With this aim in mind, we provide a formal characterisation of BPMN collaborations and some of the most significant correctness properties in the business process domain; namely, well-structuredness, safeness and soundness. We exploit this formalisation to classify BPMN models according to the properties they satisfy and their compositionality, resulting in a systematic study that gives evidence of expected results, closes conjectures and provides novel results. An experimentation to assess the impact of the considered properties on the practice of modelling is carried out on the BPMN models available in a public and populated repository.

BPMN标准在同一组织内的业务流程建模或涉及多个交互参与者的协作中具有巨大的优势。业务流程管理社区已广泛接受这种表示法的可靠正式框架可以帮助设计人员正确理解其BPMN模型以及陈述和验证模型属性。考虑到这一目标，我们提供了BPMN合作的正式表征以及业务流程领域中一些最重要的正确性。即结构合理，安全可靠。我们利用这种形式化根据它们满足的特性及其组成对BPMN模型进行分类，从而进行了系统的研究，该研究提供了预期结果的证据，关闭了猜想并提供了新颖的结果。
