    Dear All, URGENT PLEASE

    I have this error comment in the mod file for these 3 constraints; (ctinv1,2 &3):

    ctinv1: 1000000 *(1-bft)>= FQf2t[f][t]>= q*(1-bft);
     forall (f in fabric, t in periods)
    ctinv2: 0 <=FQf1t[f][t]<= q*bft;
     forall (f in fabric, t in periods)
    ctinv3: q*(1-bft)<=FQf2t[f][t]<= 1000000 *(1-bft);

    the bft is a dvar boolean.

    Any help?

    Hi,

    writing 

    x<=y<=z

    is not allowed If x ans z contain dvar or dexpr

    Can you try to replace this by

    x<=y;

    y<=z;

    ?

    regards
