Exploratory study of constraints on design by functional requirements and manufacturing

Some of the concepts and terminology of the axiomatic approach to design and manufacturing are presented. The manner in which this approach fits into the overall design process is illustrated. Two axioms are derived: maintain the independence of functional requirements; and minimize the information content. Coupling in a design as it relates to the first axiom is discussed. Some quantitative measures of coupling are presented with examples to illustrate the concepts of coupled and uncoupled designs. The issue of complexity in design and manufacturing is considered, including the relativity and consequences of a particular measure of complexity.
