bulc_set_exit_assignment
Destructive
Configure evacuation agent exit selection strategy to optimize building evacuation flow using modes like nearest exit, shortest path, or balanced distribution.
Instructions
Set the exit assignment strategy for evacuation agents. Determines how agents choose which exit to use.
Input Schema
TableJSON Schema
| Name | Required | Description | Default |
|---|---|---|---|
| mode | Yes | Assignment mode: 'NEAREST' (closest exit), 'SHORTEST_PATH' (shortest walking path), 'BALANCED' (balance exit flow), 'CUSTOM' (manual assignment) | |
| balanceThreshold | No | For BALANCED mode: max agents per exit ratio difference. Default: 0.2 | |
| customAssignments | No | For CUSTOM mode: array of {agentIds: [...], exitId: '...'} assignments |
