Automated Safety Integration Analysis of Complex System Based on Functional Model

Abstract:

The development of safety critical systems becomes even harder sine the integrity and complexity of system functions and architecture grows continuously, and this kind of process involves cooperative work between safety and system engineerings during the development of products. The article presents a new approach called automated safety integrity analysis for complex system relying on functional model, and the process of safety integrity is studied by linking functional design phase using SysML(System Model Language) and Altarica Data Flow language based on risk engineering, and the given method can be analyzed automatically and iteratively during the whole life in order to unify the process between the system design and safety assessment.At last, the approach is exemplified by fuel system of aircraft to demonstrate the applicability and versatility, which explores the engineering research for the analysis technology for safety of the complex system.
