Hello

I have created another model for practice on AIMMS for inventory optimization. There are no errors during compiling however I am getting the attached error while running the procedure in the Main Execution part.

 

The model and the error have been attached as a zipped file for reference.

 

Thank you for all the help!

Took a quick look at the model and seeing some things that stick out:

  • Your variable OrderQty has also a definition in terms of OrderQty. Looks a bit cyclic
  • In your TotalCost definition, you divide a term by the variable OrderQty. You might want to see whether you can rewrite it in such a way that you do not device by orderQty because now it is a non linear program instead of a linear program which you might want to have.
