When you're setting up a simulation in Isaac Sim—say you're modeling robots in a warehouse, cars at a checkpoint, or planes at a gate—you're essentially building a queueing system. Every time an agent waits to get into a workspace, a charger, or a station, you’re dealing with queues.
It’s any scenario where multiple agents (robots, vehicles, etc.) arrive over time and need access to a limited number of resources (like docks, tools, or processors). The system has three parts:
This describes how often agents show up. In simulation terms, this could be your robot's task frequency, delivery vehicle scheduling, or customer arrival at a kiosk.
Isaac lets you script this using Python or behavior trees—so you control whether arrivals are random (stochastic) or fixed (deterministic).
This is what the agents are waiting for—charging ports, conveyor access, machine arms, CPU cycles, etc.
You define how many "servers" you have in your simulation. Each server could be a robot arm, a docking station, or a workstation.
In Isaac, you'd model this by instancing components and assigning them logic for how long they "work" on each agent (this is the service time).
This is how you decide who gets served next. Isaac doesn’t enforce this by default—you script it.
When you see a system called GI/G/s, here’s how to read it in Isaac terms:
In Isaac Sim, if you want realistic throughput, congestion, and latency modeling, you need to tune these queue settings. You’re not just animating objects—you’re modeling real-world bottlenecks.
Also: If you’re training AI (e.g., reinforcement learning), queueing effects impact your agent’s learning loop. A robot that always waits 15 seconds before action will behave very differently from one that gets immediate access.
