1981, it was called integration definition method with
the same shorted form afterwards. IDEF is a family of
modeling languages mainly used in the software
engineering. In this family, IDEF0 is a graphical
modeling method to produce a complete functional
model of an organization system or process[3-4]. In
IDEF0, the activities are graphically represented by
boxes containing an indication of their name and
number. Arrows are constraint: Inputs (I), Outputs (O),
Controls (C), Mechanisms (M). Inputs indicate
parameters that are modified by an activity, while
outputs represent the result of it. Controls indicate
factors that constrain an activity, while mechanisms are
tools used to perform it. The result of an IDEF0
representation is a hierarchical functional
decomposition. The single function presented in the top
layer may be decomposed into its major sub-functions
by creating its child diagram. In turn, each of these
sub-functions may be decomposed, each creating
another lower-level child diagram, as illustrated in
Fig.1.
