  • 1.  Relaxed solution

    Hi

    I have a model which is giving me relaxed solutions. I tried multiple ways to formulate the constraints to avoid it but it didn't work. Please have a look in the model and any possible solutions would be a great help for me. Thank you

    Model is attached as Forum.mod
    Data file is Data.dat
    Remaining file is data source file

    Hi,

    if you label your demand constraint

    forall(o in ORDER,t in PRODUCT:Demand[t][o]>0){
ctDemand:S[t][o] - Y[t][o]*Demand[t][o] >= 0;
}​


    then you ll get which demand cannot be met in the relaxation tab
