Systemite offers a Hazard Analysis and Risk Assessment (HARA) solution that covers all of your hazard identification work from identifying hazards and hazardous events to defining safety goals. And, it's highly configurable so that you can readily integrate it into your SystemWeaver installation.
Step 1 - Hazard Identification
The first step consists of defining the Safety item and its Function (Activity) and Signal (Output). As illustrated below, you cross a Function with Guideword(s). You then review the combinations that you have identified and decide whether there is a hazard or not.
Step 2 - Hazardous Event Identification
The next step is to cross the identified Hazards from step 1 with Situation(s). You then analyze the realized combinations and make a decision as to whether there is a hazardous event or not. If there is a Hazardous event, enter values for the key attributes. Doing so, will automatically calculate an ASIL value.
Step 3 - Creation of Safety Goals
In the final step of HARA, safety goals are created to mitigate the identified hazardous events.
