Hii have a  decision variable called Q_r_p[r,p] : quantity of product p treated in facility Rhow can i obtain number of  products treated in each facility ? 

Hi,the thing is my problem is much more complicated than this. I have a logistic network in wich facilities send wastes to other facilities in the next level ( collecting facilities( called c1,c2.....

Hi,i'm facing now a modeling problem. let's say that i have a facilities that treat many type of products. and each facility has the possibility to treat one or more products and it depends on thei...

Hiin fact S_r_p is binary variable and the products that the model uses are 7 (1,2,...,7) so in maximum the total products that a facility could treat is 7 and the minimum is 0 γr is constant for a...

Hi,thank you for responding  i had another idea wich is is  to have 2 constraints : the first one will work for the case of sum(S_r_p)=1 to 7 and the secod one will enforce that the facility will n...

Hi,this is my case

Hi, thank you for respondingi have another question. i'm calculting transport cost of all nodes of a network. the transport cost parameter ($/weight) is not constant. it  depends on the weight of t...

Hi,thank you for responding i'm trying to develop a network design model. i have two sets : facilities R  and products P S_r_p : binary variable that is equal to 1 if facility r treat product p in ...
