‘De minimis risk’ is a basic concept and principle of risk analysis, which states that risks which are sufficiently small can be ignored. This principle is commonly used in practical risk analysis and related decision-making, but its rationale is debated. Recently, authors have argued that de minimis reasoning has no place in rational decision-making. The present paper provides a perspective on the foundation and use of this principle in a risk analysis context. The main aim of the paper is to gain new knowledge about the meaning and scope of the principle in view of contemporary risk science. We evaluate the extent to which different perspectives on risk can explain the disputes concerning the suitability of the principle. Current discussions of the principle have to a large extent been based on probabilistic-based frameworks, whereas the present study also addresses uncertainty-based risk perspectives. Examples are used to illustrate the discussion.

“最低风险”是风险分析的一个基本概念和原则，它指出足够小的风险可以被忽略。该原则常用于实际风险分析和相关决策，但其原理存在争议。最近，作者认为微量推理在理性决策中没有立足之地。本文提供了有关在风险分析环境中这一原则的基础和使用的观点。本文的主要目的是从当代风险科学的角度获得有关该原则含义和范围的新知识。我们评估风险的不同观点在多大程度上可以解释有关原则适用性的争议。当前对该原则的讨论在很大程度上基于概率框架，而本研究还涉及基于不确定性的风险观点。示例用于说明讨论。
