STPA STPA based safety simulation system and method computer readable recording medium

摘要

The present invention relates to an STPA-based safety simulation system and method, a computer-readable recording medium, and in a STPA-based safety simulation system using a computer including a processing unit, a storage unit, and an input/output unit, the processing unit is a structural diagram of a system subject to safety analysis A system analysis module for creating, a risk source identification module for identifying a risk source in the structural diagram, a risk situation identification module for identifying a plurality of risk situations as a cause of the cause of the risk source, and a plurality of risk situations A safety requirements analysis module that identifies safety requirements that can be solved, and a test scenario analysis in which a plurality of risk situations and multiple risk situations are input and a test scenario is prepared, but a test scenario analysis in which a plurality of risk situations and the same number of scenarios are created The module includes a test case analysis module that creates and analyzes test cases according to each test scenario by adding the structure diagram to the scenarios of the test scenario analysis module.
