RAMSU Approach for a Biomedical Safety
Critical Automated System
The automated systems described in
this presentation are complex systems composed of two main
sub-systems: hardware and software. The Reliability, Availability
and Maintainability (RAM) analysis approaches to these subsystems
are very different. Moreover the Reliability, Availability,
Maintainability and Safety (RAMS) approach applied to the Safety
Critical System has to comply with international standards (such as IEC,
CENELEC, etc.) and has to include the optimization of the
Human-Machine Action (also called Human Factors or Usability).
This presentation describes an integrated approach applied to a
Biomedical Safety Critical Automated System oriented to the
optimization of Reliability, Maintainability, Availability, Safety
and Usability (RAMSU) during all phases of the Product Life Cycle.
This approach can help the management of an organization to assess
and orient all the pre- and post-production activities for patient
risk reduction. Taking into account that time and cost are two
important requirements of any project, it is possible to perform
only a limited number of RAMSU activities; therefore it is important
for an organization to decide to perform the most effective RAMSU
activities.
