The aim of this study is to propose a set of necessary and sufficient conditions for robustness. To this end, a set of definitions and a postulate about unpredictable variability and uncertainty are presented, proving that minimising the number and strength of dependences is a sufficient and necessary condition for robustness and value. They also proved that Axiomatic Design's Independence and Information Axioms can be derived as theorems in the frame of this work. Several academic and industrial examples are presented to illustrate the results. Finally, the internal and external consistency of the theory, enunciated as the Principle of Weaker Dependences, is discussed as well as its generalisation in terms of the Principle of Reflexive Practice.

稳健的概念设计过程的理想输出

本研究的目的是提出一套稳健性的充分必要条件。为此，提出了一组关于不可预测的可变性和不确定性的定义和假设，证明最小化依赖的数量和强度是稳健性和价值的充分必要条件。他们还证明了公理设计的独立性和信息公理可以作为这项工作框架中的定理导出。提供了几个学术和工业示例来说明结果。最后，讨论了该理论的内部和外部一致性，即弱依赖原则，以及它在反思实践原则方面的概括。
