Function, behaviour, and structure, in J. Gero ed., Applications of

Although the words function, behaviour, and structure are used in
various fields, their definitions are not clear and differ in the fields. In
this paper, we define function, behaviour, and state, which is considered as
structure, and the relationships among them. we propose the FBS
(Function-Behaviour-State) diagram as a framework to model a system with its
functional descriptions. Because functions of a system cannot be described
objectively, the model should be divided into subjective part and objective
part. The consistency of the objective part should be managed by using
physical laws. The FBS diagram also represents a functional hierarchy of a
system and the way to construct the hierarchy based on relationships among
views which are representation schemes for behaviours and states. By using
this diagram, advantages and drawbacks of modeling techniques and design
methodologies are discussed.
