ABSTRACT
Independence of design, information and complexity are
the basic concepts of Axiomatic Design. These basic
concepts have proven to be generic; axiomatic design was
successfully applied in many markets and on a broad range of
products and services. Information, or entropy, plays a central
role in Axiomatic Design. In this paper an attempt is made to
organise the different kinds of information, understand them,
and evaluate the consequences of the ways they can be
applied. A number of six kinds of information are reduced to
two most determining kinds of information for the design.
Unorganised information is about choosing the right and
independent design relations. Axiomatic information is about
further optimisation of these design relations. This paper
leads to the confirmation that axiom 1 & 2 are in fact
corollaries of the complexity axiom that is constituted of the
two kinds of information. Though this revises the foundation
of Axiomatic Design, the operation and practical application
are not much affected for a number of reasons. One of them
is that a higher axiom does not alter the basic ideas behind
Axiomatic Design; it remains axiomatic.
