Assistance Device for Risk Assessment Document Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
During the creation of requirement definition documents, there is a risk of insufficient security countermeasures due to differences between the constituent element subject to risk analysis and the element receiving the countermeasure, leading to uncertainty in applying appropriate countermeasures and describing them effectively, which hinders the quality of work and increases the time required for risk assessment.
Innovation Solution
An assistance device and system that includes storage units for characteristic words and risk countermeasures, an extraction unit to match input words with similar characteristic words, and a presentation unit to display relevant countermeasure information, facilitating efficient risk assessment and document creation by minimizing missed security requirements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If risk countermeasures are applied based on individual constituent elements using traditional RCM methods, then the structure is simple and easy to understand, but security requirements may be insufficient when the constituent element subject to risk analysis differs from the element receiving the countermeasure
Solution Approach 1:
The patent introduces an assistance device as an intermediary between the risk assessment data and the requirement definition document. This device automatically extracts constituent elements, identifies applicable risk countermeasures, and generates requirement definitions, thereby ensuring completeness of security requirements without significantly increasing system complexity.
Solution Approach 2:
The assistance device performs self-service by automatically processing risk assessment data, extracting relevant information, and generating requirement definitions without manual intervention. This automation ensures that security requirements are comprehensively captured while maintaining simplicity in the overall process.
2Productivity
If manual risk assessment and document creation is performed, then flexibility in handling various scenarios is maintained, but the time required for risk assessment work increases
Solution Approach 1:
The assistance device performs preliminary actions by pre-processing risk assessment data, extracting constituent elements, and preparing requirement definition templates before the actual document creation process. This preliminary automation significantly reduces the time required for risk assessment work while maintaining flexibility.
Solution Approach 2:
The patent replaces the manual mechanical process of risk assessment and document creation with an automated assistance device. This substitution dramatically improves productivity by eliminating manual repetition while preserving the ability to handle various scenarios through configurable processing rules.
3Manufacturing precision
If uncertainty exists about which countermeasure to apply to which constituent element, then expert judgment can be applied, but the quality of work deteriorates and rework increases
Solution Approach 1:
The assistance device incorporates feedback mechanisms that automatically verify the appropriateness of matched risk countermeasures against the extracted constituent elements. This feedback loop ensures high quality requirement definitions by validating each mapping, while the automated nature maintains ease of operation.
Solution Approach 2:
The assistance device acts as an intelligent intermediary that resolves the uncertainty between constituent elements and appropriate countermeasures. It uses automated analysis to determine the correct mappings, thereby ensuring high quality requirement definitions without burdening operators with complex decision-making.
