Does anybody get this error while modeling worker scenarios in Version 13
"The following objects are located in barred areas and cannot be reached by workers:"
getting this error in the middle of the simulation run for some workplaces.
where as the worker performs at the same workplaces before this error comes
Please suggest if a solution is known
I assume that your whole simulation (or at least a large part in which workers shall walk) is surrounded by a graphic.
We changed the behaviour of barred areas from version 13.0.0 to 13.0.1.
Could you please update your Plant Simulation version and check whether that problem is still present?
The visibility of graphics shall actually have no effect on the routing behaviour of workers.
Since the problem probably appeared with version 13.0.1, I think I've got a pretty good guess what happens:
We calculate the obstacles for workers in the simulation. To keep the number of obstacles as short as possible (the simulation needs to run fast, after all), we try to throw away as many obstacles as possible. Therefore, easily structured obstacle contours that surround other obstacle contours totally, remove those other contours.
This is principially a good idea as long as noone tries to build a whole simulation or a complete part of one inside an obstacle which actually happened. Factory wall graphics were amongst the most common causes for such accidental obstacles. Therefore, we fine-tuned the contour removal mechanism by keeping obstacle contours from removing others if they contained a WorkerPool or a Workplace.
This solved two problems:
I believe you ran into the first problem meaning the simulation in version 13.0.0 only ran because all the obstacles were ignored. What you have to do now (if that assumption is correct, that is) is to check the location of your WorkerPools and Workplaces and to make sure they are outside of obstacle contours.
You can press the 'O' key inside your simulation frame to visualize your obstacles.
Thanks for the detailed reponse and insight in the working of plant Sim.
For the immediate need, I switched back to an old version of the model in V13.0.
May be there was some mistake made in the model during debugging and correction which caused this.
I selected "obstacle for worker" as "None" for most of the objects on the floor including the layout itself, As collision and interference is not of significance here (Paths are predefined)
