Abstract:

Hierarchical models of manufacturing systems can be systematically derived by model refinements in which simple components of a preliminary, more abstract model are replaced by their more detailed representations. In order to model concurrent activities and interactions of different components of manufacturing systems, Petri nets are used as the modeling platform with a formally defined operation of net refinements. The durations of modeled activities are represented by timing information associated with transitions of the model. Structural analysis is used to derive the basic performance measures, such as throughput or cycle time. The approach is illustrated by simple examples of modeling and performance analysis.
