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, and to a computer-readable recording medium, wherein in an 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 to be analyzed for safety. A system analysis module that creates a system analysis module, a risk source identification module that identifies a risk source in the structural diagram, a risk situation identification module that identifies a plurality of risk situations that are the cause of the occurrence 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 test scenario is created by receiving the above risk sources and a plurality of dangerous situations, but creating the same number of scenarios with the number of risk situations And a test case analysis module for creating and analyzing test cases according to each test scenario by adding the structure diagram to the scenario of the test scenario analysis module and a module.
