An Early Look at the UML Profile for Schedulability, Performance, and Time for Engineering Large Scale Airborne C2ISR Platforms
Abstract
This paper discusses an investigation into the utility of the Object Management Group's UML Profile for Schedulability, Performance, and Time (RT-UML Profile) for engineering a next generation of network centric, large-scale Command, Control, Intelligence, Surveillance, and Reconnaissance (C2ISR) aircraft. This activity applied the Profile in analysis of a multi-aircraft scenario, loosely based on DARPA's AMSTE research program. In this configuration, two aircraft, each with sensing capability, collaborate in real-time to develop precision targeting information for ground targets which is sent directly to in-flight munitions. This collaboration presents stressing, real-time requirements on a number of distributed, physically distinct platforms. The "RT-UML Profile" was used in conjunction with two commercial tools to perform analysis of the timing needs. Results of this activity indicate (1) the Profile assists engineers in developing better insight into temporal properties; (2) the Profile fits well within the DoD development processes; (3) use of sequence diagrams scales well for defining system load; and (4) the Profile should more directly support threads that span software processes and physical resources.
