Among the difficult and complex stages of STPA analysis, creating Loss Scenarios based on Unsafe Control Actions (UCAs) is often the most challenging part for analysts. Differences in the capabilities and experiences of individual analysts lead to significant variations in the quantity and quality of generated scenarios, and omissions due to human error are also likely to occur.
<Deriving UCAs and creating Loss Scenarios requires assistance, even for experts.>
To minimize these analytical variations and human errors, VisualPro STPA has introduced a feature that assists the analysis process through an AI Agent Chat. While this feature cannot completely replace experienced STPA analysts, it serves as a guide for beginners and provides new insights for seasoned experts.
<The 4-Class Based Loss Scenario Approach>
By attaching an MS Excel file that defines the classes of Loss Scenarios (the 4-Class based loss scenario approach will be explained in a separate document), we request the generation of loss scenarios for UCA-P-3 via AI Chat based on these criteria.
<Users can review the loss scenarios generated by AI Chat and decide whether to add them.>
Connected via MCP (Model Context Protocol), the AI Chat cross-verifies data between MS Excel and VisualPro to generate loss scenarios deemed highly relevant. A total of 15 scenarios were generated based on the 4-class approach: 4 in Class 1, 4 in Class 2, 3 in Class 3, and 3 in Class 4. Please note that the response generation speed of the AI Chat may vary depending on the performance of the AI model being used.
<Instructing AI Chat to input the newly generated loss scenarios into VisualPro.>
Once all relevant loss scenarios are generated, they can be directly added to the corresponding sections in VisualPro after a review. As shown in the image, you can review the generated data on the VisualPro screen. You can verify that 15 loss scenarios, created using the 4-class based approach and ranging from LS-6 to LS-20, have been added to the Loss Scenario section.
This feature helps identify potential blind spots that the analyst might have missed and provides clear guidance, making the overall analysis process much more efficient. Experience a smoother and more intuitive STPA analysis with VisualPro.
Building a Secure AI Environment Free from Security Threats: On-Premise & Frontier Models
VWAY supports two types of AI integration methods tailored to the data security policies and requirements of our clients.
Frontier Model Integration: We deliver top-tier performance through API integration with the latest high-performance AI models (e.g., GPT-5, Claude).
On-Premise (Closed Network) Deployment: For clients in fields sensitive to data leaks (defense, automotive, aerospace, etc.), we deploy enhanced-security sLLMs (Smaller Large Language Models) on their internal servers, safely supporting AI features locally without any external data exchange.
Conclusion: The Future of Safety Analysis with VisualPro
VisualPro, which supports various safety analysis techniques such as STPA, FMEA, FTA, and TARA, is now evolving beyond a simple "tool" into an "intelligent partner" for engineers. Save time and streamline procedures for repetitive and complex tasks with the help of AI, and allow engineers to focus the time saved on the more critical work of safety design and verification.
VWAY will build the most convenient and secure AI analysis environment, optimized for your company's data ecosystem.
