Dynamic DES

Dynamic DES is a high-performance, real-time control plane for SimPy.

It bridges the gap between static discrete-event simulations and the live world by allowing you to update simulation parameters (arrivals, service times, capacities) and stream telemetry and events via Kafka, Redis, or PostgreSQL without stopping the simulation.

Key Features

• ⚡ Real-Time Control: Synchronize SimPy with the system clock using DynamicRealtimeEnvironment.
• 🔗 Dynamic Registry: Dynamic, path-based updates (e.g., Line_A.arrival.rate) that trigger instant logic changes.
• 🚀 High Throughput: Optimized to handle high throughput using orjson and local batching.
• 🔋 Flexible Resources: DynamicResource provides prioritized queuing with graceful capacity shrinking.
• 🔌 Modular Connectors: Plugin-based architecture for Kafka, Redis, Postgres and Local testing.
• 📊 System Observability: Built-in lag monitoring to track simulation drift from real-world time, exposed via the telemetry stream.
