SysML Scheduling & Variants in Cameo: Milestones, Decisions, Backups

Answering a subscriber question on how to model schedules, link interdependent systems, and add backup/contingency paths in SysML using Cameo Systems Modeler. We walk through a temperature-sensor → gateway → API (v1/v2) → dashboard example, show how to model an assembly schedule (not system runtime behavior), wire requirements to decision points, and handle product line/variant selections (multiplicity, abstract API, specific classifiers).

What you’ll learn

Assembly schedule vs. system behavior (and when each belongs in Cameo)

Milestones, decision points, and contingency/backup paths

Requirements-driven branching (e.g., data rate ≥ 1 Hz, loss ≤ 5%)

Variant modeling: multiplicities, cleanup to reduce clutter

Abstract “API” with specific classifiers (v1, v2, v3) for plug-and-play selection
