Cost, Logic, and Seed
Beyond the type-specific settings on its General tab, every route shares three tabs that work the same way on any route type: Cost, Action Logic, and Seed. Each route article links here rather than repeating them.
The Cost tab assigns a cost to a route and classifies it for reporting.
- Classification (VA / RNVA / NVA): marks the move as Value-Added, Real Non-Value-Added, or Non-Value-Added for Impact Analysis reporting.
- Cost Per Move: the amount charged each time an entity takes this route. It is added to the entity’s built-in Cost attribute after the move completes. The default is 0. Cost affects reporting only, never the model’s behavior.
Action Logic
Section titled “Action Logic”The Action Logic tab runs logic each time an entity takes the route.
Use it to record custom statistics, adjust variables or attributes, or add extra control over the move. A route’s action logic runs after the entity has secured capacity at the destination, met the route’s condition, and (if needed) acquired its resource; once the logic finishes, the move begins. Write it inline, or select Open Editor for the full editor.
The Seed tab controls randomness on the route.
Check Enable seed control to use a fixed seed, so any random choice on this route produces the same result on every run. Leave it off for normal run-to-run variation.
