AssociatedStationOverload is always -infinity

[Sreenath Chalil Madathil]

I am recreating the model 5.3 of the Simio and Simulation textbook. When I create the list and run the model, with selection expression in the output@placement node as below candidate.Node.AssociatedStationOverLoad, all entities goes only to finepinchfaststation. However, when I use Candidate.Node.AssociatedStationLoad it selects all desitnation loads. Is there any change to the Candidate.Node.AssociatedStationOverLoad? I displayed the values in the facility window and it is coming as -infinity.

It seems the buffer capacity of the FinishedPitchFastStation is set to zero in the original file that comes with the book but was not explained in the book about this.

Yes, the buffer is set to 0 in the model distributed with the book.  The book verbiage mentions that using Infinity for buffers will cause a tie in the selection logic, but we need to add some additional discussion about the differences between using values of 0, 1, 2, etc. for the buffer capacities.
