M. Silva Significant changes have been occurring in industrialized
countries since the Second World War. Production is moving towards
sophisticated high qUality products, economy of scale has been
replaced by economy of scope, jerky demands are progressively
replacing steady demands, and competi tiveness is becoming a
worldwide phenomenon. These trends require highly automated
manufacturing systems with small set-up times and high flex
ibility. As a consequence, implementation and running costs of
modem manufacturing systems are drastically increasing, whereas
their fields of application remain limited, and every day become
even narrower, which increases the risk of early obsolescence. This
is the reason why designers are trying to improve the preliminary
design phase, also known as the 'paper study phase'. The
preliminary design phase includes, but is not limited to, the func
tional specification, and the evaluation of the system. Many tools
exist to support the functional specification of manufactur ing
systems. IDEFO is one of these tools. It leads, using a top-down ap
proach, to a precise functional description of the required system.
However, its use cannot be extended further. In general, the
evaluation starts with a modeling step, which depends on the
evaluation tool used, and ends by applying the model to find out
its main dynamic characteristics. Two main approaches can be used
to perform this task, namely simulation and math ematical approach.
Using simulation, the modeling tool is either a classical computer
language, or a simulation language."
