Phân tích an toàn chức năng là một cách tiếp cận có hệ thống được sử dụng để xác định, truy cập và giảm thiểu rủi ro liên quan đến hành vi chức năng của các hệ thống quan trọng về an toàn. Các vấn đề chính của phân tích an toàn chức năng bao gồm xác định mối nguy, đánh giá rủi ro và thực hiện các biện pháp an toàn để giảm xác suất và mức độ nghiêm trọng của tai nạn và thương tích. Phân tích an toàn chức năng là rất quan trọng để đảm bảo rằng các hệ thống quan trọng về an toàn đáp ứng mức độ toàn vẹn an toàn cần thiết (SIL) và tuân thủ các tiêu chuẩn và quy định liên quan, chẳng hạn như ISO 26262, ARP 4761, ISO 21434, ISO 21448, IEC 61508, MIL-STD-882E

1. Risk Assessment and Hazard Analysis: Identifying and mitigating potential risks early in the development process.
2. Safety Concept and Design: Creating a detailed safety concept and design that meets your specific requirements.
3. Verification and Validation: Conducting comprehensive verification and validation to ensure the system performs safely under all conditions.
4. Certification Support: Assisting with the certification process to ensure compliance with relevant safety standards.
We specialize in providing top-notch solutions for Hazard Analysis and Risk Assessment (HARA) in compliance with ISO 26262.
HARA is a fundamental process in functional safety, involving the systematic identification of potential hazards, analysis of their causes and effects, and assessment of associated risks to safety-critical systems or products. This critical process ensures that safety-critical systems meet the required safety objectives and standards.
Xác định các yêu cầu quan trọng về an toàn đối với tính toàn vẹn của hệ thống ở các cấp độ khác nhau
Our solutions for Safety Goals and Requirements (SG & SR) modelling comply with ISO 26262. SG & SR modelling is a structured approach used throughout the development lifecycle of safety-critical systems. Safety goals represent high-level objectives related to system safety, such as minimizing the risk of harm to users, passengers, or the environment. These goals, derived from safety standards and hazard analysis, are complemented by safety requirements, which detail the functionality, performance, and constraints necessary to ensure safe operation. Safety requirements encompass various aspects such as functional safety, hardware safety, software safety, and operational safety.
We offer comprehensive solutions for reliability analysis of all E/E systems, adhering to all relevant safety standards.
Reliability prediction for HW E/E components involves defining the failure modes of the component, distribution of the failure modes, and failure rate calculation using different failure rate catalogs tailored for various industries.
Our expertise extends to qualitative safety analysis, including Failure Mode and Effects Analysis (FMEA) and Failure Mode, Effects, and Criticality Analysis (FMECA), in compliance with all safety standards.
FMEA is a systematic approach to identify and mitigate potential failure modes within a system, product, or process, enhancing reliability and safety. FMECA goes a step further by assigning criticality rankings based on factors such as severity, system mission or function, and the likelihood of failure occurrence.
Phân tích nguyên nhân gốc rễ (Root Cause) để điều hướng hệ thống bằng cách sử dụng phân tích FTA
We provide advanced solutions for both qualitative and quantitative Fault Tree Analysis (FTA) in accordance with all safety standards. FTA is a deductive technique used to identify and analyze potential causes of system failures. It involves constructing a graphical representation called a fault tree to model relationships between various events and their potential outcomes, using logical gates such as AND, OR, and NOT to trace intermediate events leading to the top event.
Truy cập độ tin cậy của thành phần & chế độ lỗi cho các hệ thống quan trọng về an toàn
Our solutions encompass Failure Modes, Effects, and Diagnostic Analysis (FMEDA) in compliance with ISO 26262. FMEDA is a systematic and quantitative method used to assess the reliability of complex systems. This analysis involves identifying potential failure modes, understanding their effects on system performance, and evaluating the effectiveness of diagnostic measures using SPFM and LFM techniques.
We offer solutions for various quantitative analyses, including Reliability Block Diagram (RBD) in compliance with all safety standards.
RBD is a graphical representation used to model and analyze the reliability of complex systems by depicting relationships between components or subsystems and their contribution to overall system reliability. The blocks are connected in series, parallel, or a combination of both, reflecting the system’s configuration and inter-component relationships.
Hiểu các trục trặc hệ thống hoặc Phân tích sự phụ thuộc của một hệ thống.
Our services include Dependent Failure Analysis (DFA) in compliance with ISO 26262. DFA assesses the potential for failures within a system that may be influenced by other failures. This analysis helps engineers identify critical failure modes, assess their impact on system reliability and safety, and implement appropriate mitigation measures, ensuring the robustness and reliability of complex systems by addressing potential failure scenarios and their interdependencies proactively.
