Interface Data Modeling to Detect and Diagnose Intersystem Faults for Designing and Integrating System of Systems

Table 1

Preinvestigated interface protocols in 2 types of submarines.

Submarine type	Number of subsystems	Number of interfaces	Number of messages
First-generation class	11	12	74
Third-generation class	11	31	114
Total number	22	43	188

Subsystems to be analyzed are (1) radar, navigation, acoustic, and optical sensor systems and (2) control systems such as plotting boards and weapons control systems.
