Activities
Set up activities, their capacity and timing, and what happens to entities while they are inside.
- ActivityThe activity is the step where work happens: capacity, processing time, cost, action logic, and how to track its contents.
- QueueA waiting area where entities line up between steps, with a capacity and a release order you choose.
- BatchCombine several entities into one batch that moves on together, and control the size, timing, and grouping.
- UnbatchSplit a batch back into individual entities, either the originals or a set number of new ones.
- GateA barrier that opens and closes on a schedule, a signal, or downstream demand to control when entities move on.
- SignalA named on/off flag that lets one part of the model tell another what has happened, read by gates and logic.
- DecisionA branch point that sends each entity down one of several paths set on its outgoing connectors.
- Process GroupGather a set of steps into one container that collapses and expands, with its own roll-up results.
- InventoryThe Inventory node: a stock location of named items with reorder levels, zones, and automatic replenishment.
