Modeling concepts

• channel– A channel over which the system

communicates with its environment

• state– A named state in model

• send ‘label’– Specifies that system can send ‘label’

• receive ‘label’– Specifies that system can receive ‘label’

31

Start: A simple model

• Initialize service

• Signon

• Open

• Article registration

• Close

• Pay

• Reset to idle32

Pleasant modeling

• macro’s

• behaviors

• choice

• repeat
