Goal-Oriented Modeling of an Urban Subway Control System Using KAOS

The extent to which a safety-critical system, such as an urban subway control accomplishes its goals is fundamental metric of success. Identifying and assessing these should thus be one the primary tasks in system development. breakdown systems may result loss human lives assets. failure caused by insufficient, incomplete, ambiguous, or conflicting requirements. Non-functional requirements are also separated from requirement specifications. Goal-oriented engineering methodologies, KAOS, used tackle challenges providing adequate, complete, unambiguous, consistent terms goals. As result, KAOS approach utilized this article construct goal-oriented model system. Variability obstacle concerns addressed study.
