METHOD FOR EXPRESSING CONCURRENCY THAT IS NON-FUNCTIONAL REQUIREMENTS OF SYSTEM FOR UML

摘要

PURPOSE: A method for expressing concurrency that is non-functional requirements of a system is provided to appoint/visually express a concurrent use-case to express the concurrency among the non-functional requirements together with the use-case expressing the functional requirements of the UML(Unified Modeling Language). CONSTITUTION: The functional requirements are arranged/expressed as the use-case(S710). A demand for the concurrency is checked for all arranged use-cases(S720). A group of the use-cases needing the concurrency is defined(S730). The use-case having the concurrency is converted into the concurrent use-case(S740). The group defined as the concurrent use-case is connected through a concurrent use-case relation(S750).
