safety-critical system

A computer, electronic or electromechanical system whose failure may cause injury or death to human beings. E.g. an aircraft or nuclear power station control system. Common tools used in the design of safety-critical systems are redundancy and formal methods.

See also aeroplane rule.

Some products currently integrating porous metal include various implantable devices, filters to prevent plugging of catheters, drug delivery devices, medical instrumentation, various test filters, bacteria filters, sparging devices for cell culture processing and gas flow restrictor devices for gas delivery in life-critical systems.
In life-critical systems, every possible contingency must be identified and addressed; therefore testing the software consumes a large fraction of the whole development budget.
Examples of these products include biocompatible porous titanium filters, implantable devices, metal filters in test stands, spargers used in cell-culture processes, filters to prevent plugging in catheters, and precision flow restrictors for the delivery of gases in life-critical systems.

The RISKS archives suggest that we must do better in developing and using life-critical systems, and indeed some progress is being made in reliability and human safety.
In a paper presented last week in New Orleans at the Association for Computing Machinery's conference on software for critical systems, they argue: "Without a major change in the design and verification methods used for life-critical systems, major disasters are almost certain to occur with increasing frequency.
It must be stressed that in spite of the limits and difficulties of the proposed approach, there seems to be no other solution if we wish to pursue the development of computer-based life-critical systems aimed at satisfying current safety requirements.
Most recently working as a project lead on life-critical systems projects, Al-Dahleh has led both large and small projects involving all phases of the software lifecycle for avionics and medical device manufacturers.
Nurses, physicians, pilots, civil engineers (even hair stylists) are licensed; he reiterated the thought that he would like life-critical systems to be built by licensed or certified professionals.
