SysML Web Tool

This tool provides a web-based, input-driven SysML metric calculator for MBSE teams. It accepts structured counts of blocks, relations, generalizations, and requirements to produce quantitative indicators of model quality. The architecture supports rapid comparisons between design options using objective scores rather than subjective judgments. It does not render diagrams; instead, it focuses on calculable properties that influence maintainability and traceability.
Conceptually, inputs map to a graph of SysML elements where blocks are nodes and relations are edges. Metrics such as coupling_score, cohesion_score, and max_depth summarize the architecture, while requirement_coverage indicates traceability effectiveness. The tool applies deterministic rules to derive these indicators from the provided counts, enabling repeatable assessment across iterations.
Who benefits includes systems engineers evaluating trade-offs, project managers monitoring design risk, and model authors seeking quantitative feedback to justify architectural choices. The value lies in structured, reproducible metrics that support decision cycles, not in diagram generation or diagram-specific styling. Core features include input validation, optional advanced fields for constraint blocks and traceability mappings, and export options for sharing results with stakeholders. Typical use cases are early architecture evaluation, post-synthesis design reviews, and MBSE process improvement initiatives.
The tool distinguishes itself by delivering a compact set of domain-relevant metrics with transparent calculation logic, enabling quick interpretation and cross-project benchmarking.
