The article presents a method for the analysis and verification of Use Case Map (UCM) models with scenario control structures—protected components and failure handling constructs. UCM models are analyzed and verified with the help of colored Petri nets (CPN) and the SPIN model checker. Algorithms for translating UCM scenario control structures into CPN and CPN into SPIN input language Promela are described. The number of elements of the resulting CPN model and the number of Promela model states are estimated. The presented algorithm and the verification process are illustrated by the study of a network router firmware update.
