minimize sum(t in T, i in DS, j in DS)(cost[i, j] * R[i, j, t]) + sum(t in T)(U[t] * Ft) + sum(v in V, i in SCO, j in SCO)(cost[i, j] * X[i, j, v]) + sum(v in V)(U[v] * Fv);
subject to{
forall(c in C){
forall(v in V){
M * (3 - Q[c, 1] - Y[c, v] - B[v, 2] - B[v, 3] - B[v, 4]) + sum(o in O)(K[v, o]) >= 1;
}
}
}
There is no non linearity involved in the constraint but still the opl is giving error
please help
