Combat management systems: Predicting performance early in the design lifecycle

In this paper we show how designs of COTS-based real-time systems, such as Naval combat management systems, can be realistically analysed early in their design lifecycle using the technique of executable modelling, potentially identifying problems earlier in the design lifecycle than by using traditional design methodologies, with resultant cost and time savings. Our emphasis is on verifying performance through-life as components change, and in the initial design where military off-the-shelf components may be used in a platform with different capabilities than originally intended.
