Abstract

A computer-implemented method is provided for performing mishap risk assessment within a system. The method includes providing a first set of data including risk information associated with at least one hazard within the system, correlating all input first set of data with a second set of data defined as a plurality of mishaps of the system such that the hazard correlates with each mishap to assess mishap potential, storing the correlated first and second sets of data, and performing mishap risk assessment within the system based the correlated data including the first and second sets of data.

Claims

1. A computer-implemented method for performing mishap risk assessment within a system, the method comprising:

providing a first set of data including risk information associated with at least one hazard within the system;

correlating the said first set of data to a second set of data defined as at least one mishap of the system to produce a third set of data such that each hazard of said at least one hazard correlates to each corresponding mishap of said at least one mishap for

assessing mishap potential;

storing said correlated first and second sets of data; and

performing mishap risk assessment within the system based on said third set of data including said first and second sets of data.

2. The computer-implemented method of claim 1, wherein said first set of data comprises analysis data, origin data, hazard description information, external effects information, system information, mishap association data, safety requirement information, and status information.

3. The computer-implemented method of claim 2, wherein said first set of data further comprises at least one of initial, current and projected risk assessment information.

4. The computer-implemented method of claim 2, wherein said second set of data comprises said system information, mishap description information, mishap effect information;

mishap status information and at least one of initial, current and projected mishap risk information.

5. The computer-implemented method of claim 1, wherein correlating said first set of data with said second set of data to produce said third set of data includes:

correlating a single hazard with said at least one mishap.

6. The computer-implemented method of claim 1, wherein correlating said first set of data with said second set of data includes:

correlating a plurality of hazards to a single mishap of a plurality of mishaps to determine an aggregate risk of said single mishap.

7. The computer-implemented method of claim 1, further comprising:

providing a fourth set of data including causal information associated with said at least one hazard of the system.

8. The computer-implemented method of claim 7, wherein said fourth set of data comprises known and potential causal factors, relational information between known and potential causal factors, causal origin information, associated hazard, mishap and external effects information, system information including subsystem information of any subsystem of the system.

9. The computer-implemented method of claim 4, wherein the system information comprises information corresponding to each version of the system.

10. A non-transitory computer-readable medium executable on a computer to implement a process for performing mishap risk assessment within a system, the process comprising:

providing a first set of data including risk information associated with at least one hazard within the system;

correlating said first set of data to a second set of data defined to produce at least one mishap of the system as a third set of data such that said at least one hazard correlates to each mishap of said at least one mishap for assessing mishap potential;

storing said correlated first and second sets of data; and

performing mishap risk assessment within the system based on said correlated data including said first and second sets of data.

11. The medium of claim 10, wherein the first set of data comprises analysis data, origin data, hazard description information, external effects information, system information, mishap association data and status information.

12. The medium of claim 11, wherein said first set of data further comprises at least one of initial, current and projected risk assessment information.

13. The medium of claim 11, wherein the second set of data comprises the system information, mishap description information, mishap effect information;

mishap status information and at least one of initial, current said projected mishap risk information.

14. The medium of claim 10, wherein correlating said first set of data with said second set of data to produce said third set of data includes:

correlating a single hazard with said at least one mishap.

15. The medium of claim 10, wherein correlating said first set of data with said second set of data as said third set of data includes:

correlating a plurality of hazards to a single mishap of a plurality of mishaps to determine an aggregate risk of said single mishap.

16. The medium of claim 10, further comprising:

providing a fourth set of data including causal information associated with said at least one hazard of the system.

17. The medium of claim 16, wherein the third set of data comprises known and potential causal factors, relational information between known and potential causal factors, causal origin information;

associated hazard, mishap and external effects information, system information including subsystem information of any subsystem of the system.

18. The medium of claim 11, wherein the system information comprises information corresponding to each version of the system.
