Increasingly, researchers and practitioners operate in complex systems difficult to comprehend. In them, the multiplicity of perspectives, elements and relationships operating on multiple levels makes the practice of systems thinking and boundary critique considerably difficult. Drawing upon boundary critique and hierarchy theory, this paper presents ways of thinking in terms of multilevel boundary judgements models useful for addressing the aforementioned problem in all fields of study. A real example of the use of these models is presented. This paper also discusses how thinking in terms of multiple levels of boundary judgements is important to better deal with values and moral frameworks and to promote critical reflexivity in systemic interventions, while escaping the dangers of reductionism. Furthermore, a systemic way of exploring the role of moral frameworks in systems practice is discussed, contributing with new concepts useful to develop a deeper understanding of ethical issues in systems practice.

使用多级系统边界模型处理复杂性

越来越多的研究人员和从业者在难以理解的复杂系统中运作。在它们中，在多个层面上运行的多种观点、元素和关系使得系统思考和边界批判的实践变得相当困难。本文借鉴边界批判和层次理论，提出了多层次边界判断模型的思维方式，可用于解决所有研究领域的上述问题。介绍了使用这些模型的真实示例。本文还讨论了多层次边界判断的思考对于更好地处理价值观和道德框架以及促进系统干预中的批判性反思以及避免还原论的危险是如何重要的。此外，
