Abstract
Recent business processes (BP) need more speed than what they were, and therefore the time constraints are important. Among many kinds of notation, UML is one of the alternatives to be taken into account for the information systems. Although UML provides us with 13 types of diagrams, only the sequence and timing diagrams can express the time constraints. While the former is suitable for modeling the global behavior, the latter focuses on more local behavior. The BP shows global behavior, therefore this paper uses the sequence diagram, and presents how the BP is modeled verified from behavioral viewpoints including time constraints. In this verification, we use the UPPAAL model checker, since UML itself is not capable of verification.
