Embodiment Construction
[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0035] see Figure 1-4 , a HAZOP-based BowTie analysis software comprising the following steps,
[0036] Step 1: Determine the mapping relationship between the associated elements between HAZOP and BowTie, that is, deviation-top event, cause-threat, consequence-consequence, protective measure-barrier.
[0037] Step 2: Partially optimize the HAZOP analysis, and refine the protection measures into preventive protection measures and mitigation protection measure...

The invention relates to the technical field of risk analysis software, and discloses HAZOP-based BowTie analysis software which comprises the following steps: step 1, determining a mapping relation of associated elements between HAZOP and BowTie, namely deviation-top events, reasons-threats, consequences-consequences and protective measures-barriers, step 2, carrying out partial optimization on HAZOP analysis, the protection measures are refined into prevention type protection measures and mitigation type protection measures, so that the prevention type protection measures and the mitigation type protection measures accurately correspond to a BowTie barrier, namely, prevention type protection measures-prevention type barriers and mitigation type protection measures-mitigation type barriers. According to the BowTie analysis software based on the HAZOP, two analysis methods which are originally independent from each other are associated from internal logic and algorithm, a user not only can independently carry out HAZOP analysis and BowTie analysis, but also can directly generate BowTie analysis on the basis of the HAZOP analysis, the requirement of the user for carrying out BowTie analysis on the basis of the HAZOP analysis is met, and the efficiency of analysis work is greatly improved.
Description
technical field [0001] The invention relates to the technical field of risk analysis software, in particular to a HAZOP-based BowTie analysis software. Background technique [0002] HAZOP (Hazard and Operability Analysis) and BowTie (Bowtie / Bowtie Analysis) are two independent analysis methods in the field of risk analysis. They are different in analysis process, presentation form and application scenarios. But the two are related in some aspects: 1. There is a progressive relationship in the application scenario, and the analysis results of HAZOP can be used as the information input of BowTie; 2. The analysis elements are highly overlapping. Therefore, how to quickly transform the analysis results based on HAZOP into BowTie analysis has become a demand in the industry. [0003] There is no tool or software in the industry that directly converts HAZOP to BowTie. But due to the associative nature between HAZOP and BowTie, there has always been a need to generate BowTie from...
