Smart waste management system modeled with UML class and activity diagrams covering user roles, bin sensors, and collection workflows. The class diagram defines seven core entities—Utilisateur, Proprietaire, Agent, Poubelle, Notification, HistoriqueRemplissage, Collecte, Alerte, and CommandeDeplacement—with relationships capturing ownership, monitoring, and dispatch logic. Activity diagrams detail seven key processes: proprietor registration, user login, fill-level consultation, alert generation when bins exceed 80%, autonomous bin movement with obstacle detection, agent-driven collection, and backend notification handling. This architecture demonstrates how to structure a complete IoT platform combining real-time sensor data, user management, and operational workflows for waste collection optimization. Fork and customize this diagram on Diagrams.so to adapt it for your municipality or waste management startup. The model supports multi-tenant operations with role-based access control and geolocation tracking.
