Performing summation of entities in the Queue [Arena Simulation]

Question

In my model in ARENA, I have 22 QUEUE which I would like to SUM their values and display in my animation. The problem is my expression length exceeds the 256 character limit and hence I am stuck. Here is what my desired expression looks like:

NQ(TRAFFIC LIGHT AT N1.Queue) + NQ(TRAFFIC LIGHT AT N2.Queue) + NQ(TRAFFIC LIGHT AT N3.Queue) + NQ(TRAFFIC LIGHT AT N4.Queue) + NQ(TRAFFIC LIGHT AT N5.Queue) + NQ(TRAFFIC LIGHT AT N6.Queue) + NQ(TRAFFIC LIGHT AT N7.Queue) + NQ(TRAFFIC LIGHT AT N8.Queue) + NQ(TRAFFIC LIGHT AT N9.Queue) + NQ(TRAFFIC LIGHT AT N10.Queue) + NQ(TRAFFIC LIGHT AT N11.Queue) + NQ(TRAFFIC LIGHT AT N12.Queue) + NQ(TRAFFIC LIGHT AT N13.Queue) + NQ(TRAFFIC LIGHT AT N14.Queue) + NQ(TRAFFIC LIGHT AT N15.Queue) + NQ(TRAFFIC LIGHT AT N16.Queue) + NQ(TRAFFIC LIGHT AT N17.Queue) + NQ(TRAFFIC LIGHT AT N18.Queue) + NQ(TRAFFIC LIGHT AT N19.Queue) + NQ(TRAFFIC LIGHT AT N20.Queue) + NQ(TRAFFIC LIGHT AT N21.Queue) + NQ(TRAFFIC LIGHT AT N22.Queue)

Any idea how I can perform this summation in my model?

Answer 1

Just for anyone who comes to this page in future, the workaround I found, was to define variables with the value of that long Query mentioned above. Arena doesn't accept long expression per se but it does accept long queries as variable values. So I defined the variable and updated that variable in every ASSIGN module that I had in the model.
