location problem

[Eriska Prasetiowati]

Good afternoon,

 

I need your help to solve the following error please. I am going to explain a part of the problem :

n  i : set of demand site

n  j : set of candidate site

n  k : set of type station  (large, medium, small)

I would like to optimize location model to minimize construction and operation costs.

error processing objective Total_Cost:

        no value for CCT[1]

Thank you
