[APRIL ROSSE PADILLA CASTANO]

I have a problem with a binary variable. It is define as: 

var Y {p in PLANT, j in LOCATION} binary;

but the result no is equal to 1 or 0. 

The result are numbers between 1 and 0: Y[p,j] =  0,8    0,9    0,7

Please, help me!

what should i do??

Hi April. I had the same problem once.

Which solver are you using? Remember that Minos ignore integrality of variables, for that reason, even if you define the variable as binary the solution will be non-integer values.

You should use, as an example, CPLEX to sove the problem and have binary values in your solution.

I've tried with GRUBI, Kintro and CPLEX. But all have the same problem.

What was the solver (e.g. CPLEX) output? Did it report finding an optimal solution?

HTH,
