Abstract:

A Real-Time Architectural Specification (RAS) approach and its application to command and control (C2) systems are presented. Our objective is to establish a formal foundation that will enable us to integrate existing rich but fragmented formal techniques for system specification and verification into a practical and scaleable formal engineering method to support the design and development of highly reliable real-time distributed systems. The contribution of RAS is twofold: First, it provides a formal system that integrates system’s timing requirements and requirements propagation into the process of architectural modeling and design in such a way that allows us to systematically enforce that the requirements are met in every step of the design process. Second, it offers an incremental and more scaleable approach for design modeling. These two features together make RAS a suitable model for the design of C2 systems. We further present an incremental method for verifying timing properties of an RAS model that helps to reduce the complexity of analysis both at a given design level and across different design levels.
