Travel distance returns the negative value

Hi,

Why the travel distance of operators return the negative value in the following model?

Is it caused by Parameter Table or A* navigator?

Thanks in advance

TravelDistance.fsm

FlexSim 22.0.4

This looks like a bug - all three operators start with zero travel distance and then as soon as they start figuring out who can move first some are initialized with negative values. I'll send in a case for this.

Is there any alternative until the bug is fixed?

We would like to perform a simulation using A* Navigator with a variable number of operators.

Travel time behaves similar to travel distance. You can evaluate different states of travel in statistics to collect this data. If you can deactivate acceleration and deceleration, you can easily correlate time and speed to distance. Otherwise there might be a deviation for acceleration times.

A bit more advanced would be a collecting of kinematics profiled data node information about travel distances or times directly. Movement action involves kinematic. You can evaluate this data node to get desired data by command getkinematics( .. )
