System and method for continuous online safety and reliability monitoring

A processor readable medium including processor-executable code to generate safety availability information for an instrumented function including a plurality of instrumented function components, the code comprising instructions for:

• obtaining, from an asset management application, operating information about at least one of the plurality of instrumented function components;
• determining a probability of failure on demand for the instrumented function based at least in part on the operating information;
• and
• generating the safety availability information based on the probability of failure on demand;
• wherein the operating information includes an indication that at least one of the plurality of instrumented function components has been replaced, and wherein the computer executable code includes instructions for resetting a time since a last test for the at least one of the plurality of instrumented function components in response to the indication.
