Entropy-based design

Abstract:

Corollary 2 from Axiomatic Design and the reduction of Quality Loss specify that the number of functional requirements must be minimal: this minimum number is one. The designer must therefore seek the path that resolves only one functional requirement on each level of the design hierarchy. If the designer manages to maintain the ideal situation (in which each design step resolves a single functional requirement), the Independence Axiom is met automatically, and therefore adds no information. This chapter proves two theorems that help channel decision-making in this case. The two theorems proposed are the Broad Tolerance Theorem and the Linearity Theorem. Both are applied to the design of a fuel supply system, ...
