Evaluation of UML- real time profiles for Industrial Control Systems

UML does not provide complete solution for real-time system especially for Industrial Control Systems (ICS). To overcome the UML limitation of expressions, number of designers of real-time systems from industry provides solution according to their environment. Stereotypes, Tagged values, and Constraints is lightweight way of extending UML. In this paper, UML profiles for real-time systems are evaluated on the basis of characteristics of Real-Time Industrial Control System (RT-ICS). After reviewing these UML Profiles, some shortcomings were identified and it was felt that a new UML profile is needed to overcome these short comings.
