Astah System Safety supports a range of
diagrams for System-Theoretic Process
Analysis (STPA) and System-Theoretic
Accident Model and Processes (STAMP)
and SCDL(Safety Concept Description
Language). These diagrams are essential
tools for conducting thorough and
effective safety analyses using the STPA
methodology. The specific types of
diagrams supported can vary, each
designed to visualize different aspects of
system control and safety.

All System Safety Diagrams

Astah System Safety is a modeling tool for safety-critical
systems to support system architecture modeling, system
safety assessment and analysis by incorporating the
following modeling languages and techniques in one tool:

• SysML
• UAF (Unified Architecture Framework)
• STAMP/STPA
• GSN/D-Case
• ASAM SCDL

Traceability is assured between models (e.g. requirements
and solutions) and API enables the integration with other
applications

We offer an UAF Assistance Plug-in that simplifies the
process of creating and managing architecture models
based on the UAF (Unified Architecture Framework) that
is defined by OMG.

• Add stereotype and color in One Action
• Efficient Search Function
• Jump to target model in Diagram
• Intuitive Access to Diagrams

UAF (Unified Architecture Framework)

STAMP (System-Theoretic Accident Model and
Processes) is an accident causality model based on
systems theory developed by Prof. Dr. Nancy Leveson at
MIT and STPA (System-Theoretic Process Analysis) is a
technique based on STAMP. Astah System Safety
provides the following diagrams and tables for your STPA
analysis process. See All Supported Diagrams

• Control Structure Diagram
• Precondition Table
• Control Loop Diagram
• UCA(Unsafe Control Action) Table
• Loss Scenario Table
• Countermeasure Table
• Loss Hazard Safety Constraint Table
• CS (Component Structure) Entire view
