Description

Astah SysML helps systems engineers capture requirements, structure, and behavior in SysML v1 without the weight of a large enterprise suite. Block definition and internal block diagrams, requirement diagrams and tables, parametric diagrams, and use case, state machine, activity, and sequence diagrams are all included, along with mind maps for early concept work. Each diagram is a view of one shared model, so updating a requirement or block keeps every related diagram in step. Assist functions such as double-click creation, creating multiple elements from text, and alignment guides reduce drawing time. Models can be exchanged through XMI and with Cameo Systems Modeler, and profiles let teams extend the language. For AI-assisted work, AI Chat Copilot connects to OpenAI, Azure OpenAI, Claude, Gemini, or any OpenAI-compatible endpoint through your own API key, and a local MCP server lets external AI agents read and work with your models. Astah SysML runs locally on Windows and macOS. It does not include simulation. Developer: Change Vision, Inc. Current version: 11.0 (March 2026).

Description

Projects in systems engineering are far more likely to achieve success when all stakeholders can actively participate in the process; however, many lack the expertise to navigate traditional systems engineering tools or engage with the intricate modeling languages commonly used. MapleMBSE addresses this challenge by providing user-friendly, Excel-based interfaces tailored to each specific task within your systems engineering project. By allowing all stakeholders to connect live to the system model, collaboration becomes seamless, enabling quicker workflows, minimizing mistakes, and curtailing unexpected expenses. Additionally, the MapleMBSE interface is designed for ease of use, granting system engineers greater adaptability for model modifications, which ultimately leads to a decrease in errors related to knowledge capture. This innovative approach fosters a more inclusive environment for stakeholder involvement, significantly enhancing project outcomes.
