Structured analysis using hierarchical predicate transition nets

In previous work, a methodology for constructing hierarchical and structured high-level Petri net specifications has been developed. The authors further explore and refine the methodology for using hierarchical high-level Petri nets in systems analysis. The approach has adapted the results from the data flow diagram method and its application to modern systems analysis. The major steps and the associated techniques of the approach are presented and demonstrated through a library system.<
