A formal framework to define margins in industrial processes


A common engineering pattern to handle uncertainties in industrial processes is to use margins, understood as an amount of something included so as to be sure of success or safety. It is supported by practices which differ depending on the discipline. This paper proposes a formal framework to describe these practices independently from the discipline considered, by introducing the concept of model of margin. The structure of the model of margin identifies the common steps between these practices. This framework can be used to formulate some general engineering questions on margins as mathematical problems, and two examples of such questions are developed. Some classical notions of margin from the literature are recasted in this framework as their associated models of margin are being constructed.
