UML sequence diagrams focus on the interaction between different classes. For distributed real
time transaction processing it is possible to end up with complex sequence diagrams, containing
messages related to system processes. It is difficult to examine alternative combinations of
message passing. A solution is to translate these diagrams into an executable processor net
model. This is based on the ‘actor model’, Petri net concepts and higher order net constructs. A
case study taken from a flight reservation scenario is introduced and used to create a processor net
model. This approach offers various advantages like identifying the main processes, executable
model creation, verification, formalization, defining schemas and performance analysis.
