Description

Astah System Safety is a comprehensive tool designed for model-based safety analysis in critical systems, created by Change Vision, Inc. This innovative software integrates SysML modeling with STAMP/STPA hazard assessments, GSN (Goal Structuring Notation) assurance cases, ASAM SCDL, and UAF, all within a single platform. By linking safety analyses directly to the system model, it ensures that control structures, hazards, and safety arguments remain traceable to both requirements and system architecture. This tool is particularly valuable for safety engineers working in sectors such as automotive, aerospace, and embedded systems, facilitating safety-case development in compliance with standards like ISO 26262. Additionally, the AI Chat Copilot feature utilizes your own API key for various services, including OpenAI and Azure OpenAI, and connects to a local MCP server to integrate external AI agents with your models. Models can be easily shared using XMI format and with Cameo Systems Modeler for enhanced collaboration. Astah System Safety is compatible with both Windows and macOS platforms, although it does not include Fault Tree Analysis (FTA) or Failure Mode and Effects Analysis (FMEA). A free trial period lasting 40 days allows potential users to explore its capabilities before committing to a purchase. Overall, this tool represents a significant advancement in ensuring the safety of complex systems.

Description

Since its inception in 1993, CORE has been the backbone for thousands of projects and has assisted tens of thousands of systems engineers. From the outset, CORE has championed the principles of what we now recognize as model-based systems engineering. By leveraging a systems metamodel that integrates with robust view generators, it enables the on-demand production of diagrams while ensuring consistency, thus fostering a generation of successful systems engineering initiatives globally. Although GENESYS is the preferred option for many organizations in the current landscape, Vitech remains committed to supporting projects and clients who continue to depend on CORE for their systems engineering requirements. Just as defining and managing interfaces in system design is crucial for success, so too is the effective management of data interrelationships, which plays a pivotal role in achieving project objectives. This holistic approach to systems engineering not only enhances productivity but also drives innovation in the field.
