Multisignal modeling for diagnosis, FMECA, and reliability

Multisignal modeling methodology is a simple and efficient knowledge representation scheme that captures the basic attributes of a system (structure, specifications, etc.) that are obtainable from design data and product specifications. QSI´s TEAMS toolset employs multisignal modeling for testability analysis, test program set development, onboard monitoring and ground support systems. We outline the modeling methodology, its use in related areas of reliability analysis and failure modes, effects and criticality analysis (FMECA), and our efforts in building a reusable test and model library
