Abstract
A system and method for managing a plurality of instrumented function components is disclosed. In one embodiment, operating information about the plurality of instrumented function components is received from an online safety availability application and status information for the plurality of instrumented function components is updated, within an asset management database, based upon the operating information. And based upon the status information, the plurality of instrumented function components are managed.
Claims39
A method for managing a plurality of instrumented function components, the method comprising:
- receiving, from an online safety availability application, operating information about the plurality of instrumented function components;
- updating, within an asset management database, status information for the plurality of instrumented function components based upon the operating information;
- determining, by a computer, a probability of failure on demand, at time of receiving the operating information, for the instrumented-function based upon the operating information;
- comparing, by a computer, the probability of failure on demand with a designed probability of failure on demand for the instrumented function to establish a variance;
- and
- managing the plurality of instrumented function components based on the status information and at least in part on the variance.
A system for managing a plurality of instrumented function components, the system comprising:
- means for receiving, from an online safety availability application, operating information about the plurality of instrumented function components;
- means for updating, within an asset management database, status information for the plurality of instrumented function components based upon the received operating information;
- means for determining a probability of failure on demand, at time of receiving the operating information, for the instrumented-function based upon the operating information;
- means for comparing the probability of failure on demand with a designed probability of failure on demand for the instrumented function to establish a variance;
- and
- means for managing the plurality of instrumented function components based on the updated status information and at least part upon the variance.
A non-transitory processor-readable medium encoded with instructions for managing a plurality of instrumented function components, the medium including instructions for:
- receiving, from an online safety availability application, operating information about the plurality of instrumented function components;
- updating, within an asset management database, status information for the plurality of instrumented function components based upon the operating information;
- determining a probability of failure on demand, at time of receiving the operating information, for the instrumented-function based upon the operating information;
- comparing the probability of failure on demand with a designed probability of failure on demand for the instrumented function to establish a variance;
- and
- managing the plurality of instrumented function components based on the status information and at least in part upon the variance.
A computer-assisted method for managing a plurality of instrumented-function components which collectively implement an instrumented function, the method comprising:
- receiving, from an online safety availability application, operating information about the plurality of instrumented-function components;
- determining, by a computer, a probability of failure on demand, at time of receiving the operating information, for the instrumented-function based on the operating information;
- comparing, by a computer, the probability of failure on demand with a designed probability of failure on demand for the instrumented function to establish a variance;
- and
- managing the plurality of instrumented function components based at least in part upon the variance.
A system for managing a plurality of instrumented function components, comprising:
- a processor;
- an input/output (I/O) module;
- and
- a memory containing instructions for execution by the processor to:
- receive operating information about the plurality of instrumented function components from the I/O module;
- provide, to an asset management database, status information for the plurality of instrumented function components based upon the operating information;
- determine a probability of failure on demand, at time of receiving the operating information, for the instrumented-function based upon the operating information;
- compare the probability of failure on demand with a designed probability of failure on demand for the instrumented function to establish a variance;
- and
- manage the plurality of instrumented function components based on the status information and at least in part on the variance.
