Method for Updating Risk Analysis Parameters of a Technical System

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent describes a computer-based method for updating risk analysis parameters, such as occurrence and detectability rates, of technical systems—especially in fields such as healthcare. The invention works by gathering actual incident report data after the system has been operating, comparing it with the original Failure Modes and Effects Analysis (FMEA) predictions, and automatically adjusting the risk parameters to better reflect real-world performance, including taking into account not only harmful events but also near misses.

Use CasesContent extracted from patent full text and abstract with AI.

• Continuous risk management and safety improvement in healthcare settings, such as radiation therapy devices or hospitals.
• Automated risk analysis updates in critical infrastructure like power plants or industrial automation systems.
• Safety-critical product lifecycle management for medical devices, transportation, or aerospace systems.
• Audit and quality assurance tools to verify actual system reliability against initial risk assessments.
• Regulatory compliance tools for industries requiring up-to-date and accurate risk documentation.

BenefitsContent extracted from patent full text and abstract with AI.

• Provides data-driven, objective updates to risk parameters, reducing reliance on subjective human estimates.
• Increases the accuracy of risk assessments by incorporating real-world incident and near-miss data.
• Improves safety by allowing faster detection and correction of underestimated risks.
• Facilitates iterative and continuous improvement in system safety and reliability.
• Enables more effective allocation of preventive and corrective measures based on actual risk trends.
• Supports regulatory compliance through up-to-date risk analysis records.

Patent Abstract

A computer-based method for updating risk analysis parameters of a proactive risk analysis of a technical system, such as of an FMEA analysis for example. The method uses incident report data obtained during posterior operation of the technical system, compares these incident report data with data of the proactive risk analysis, and updates the said risk analysis parameters in function of said comparison.
