Bonjour,
J'ai commencé à travailer sur Cplex il y a quelques jours, comment je ne suis pas familiarisée avec ce logiciel j'ai copié un exemple et l'ai fait de modifications. Mais ça ne marche pas et je suis pas capable de trouver mes erreurs. Mon modéle c'est:
min Sum (Covariance[i][j]*X[i]*X[j])
st Sum (R[i]*X[i]) =Rexp //Return Constraint
Sum (X[i])=1 //Budget Constraint
xmin[i]<= X[i] <= xmax[i] (1 i n) //Floor &Ceiling C.
max(X[i]-iniX[i],0) < Bmax (1 i n) //TurnoverPurchase C
max(iniX[i]-X[i],0) < Smax(1 i n) //TurnoverSale C.
X[i]=iniX[i] or X[i] >= (iniX[i]+Bmin) //Trading Constraint
or X[i] >= (iniX[i]-S[i])
|{i E {1,...,n}:X[i]!=0}| N //Maximun number of
elements in solution
