This paper presents two methods for the engineering of manufacturing s
ystems. The first method uses SADT for high-level system analysis and
Petri nets for behavioural modelling. A translation mechanism based on
the interval temporal logic is used to map an SADT into a correspondi
ng Petri net. The second method uses pre-established generic functiona
l and structural schemes to generate the model of the target applicati
on. This method is based on an extension of the object modelling techn
ique (OMT).
