| 摘要： | This report describes progress in 2009 on developing a unified, systematic, and semiautomated approach for extracting early information from requirements specifications and other documents, for system modeling, requirements validation, and safety analysis. Semi-automated extraction of data and generation of models and visualizations can save labor and schedule. Automated information extraction can improve the efficiency, consistency, repeatability, and completeness of modeling and analysis, and it can reduce the time spent reanalyzing when specifications and designs change. The Automated Tool and Method for System Safety Analysis project uses a linguistic analysis tool to extract key information from FMEAs and hazard reports. Model generation software in the Hazard Identification Tool integrates this information into visualizations of system architecture models. The model generation software maps extracted terms from text to elements of the model, by using criteria based on the Aerospace Ontology. The model is reused in system-level simulation, to dynamically evaluate the impact of failure modes on the executing system design. |
