The structural health monitoring (SHM) community would be well served by integrating proprietary SHM technologies developed by many different vendors and researchers into a single open systems architecture that can evolve over time. The open systems architecture should provide the ability to

  • accommodate improvements in SHM algorithms over time;

  • integrate health assessment and prognostic assessment algorithms developed by different vendors;

  • integrate data collected from several sensing structural subsystems and then to aggregate that data for the structure as a whole;

  • communicate and store SHM data, algorithm results, and recommendations from subject matter experts, and intelligent software agents.

The International Organization for Standards (ISO) and the Machinery Information Management Open Systems Alliance (MIMOSA) standards body developed and now maintain a set of standards that satisfy these needs for an open systems architecture for condition-based maintenance in the SHM domain.
