hello, i am a beginner, I have just written a glpk program. following code in
Cplex is ok, can anybody tell me, what shuld i it's corrects in GLPK.
param cost :=
[*,*,r1]: zul1 zul2 :=
Her1 30 20
Her2 22 25 ;
[*,*,r2]: zul1 zul2 :=
Her1 39 30
Her2 27 25 ;
another question, how can I correct this sentence? error by running: expression
following := has invalid type.
var rohTranMenge{r in Roh, i in Zulieferer, j in Hersteller, t in Periode}, >=0;
param sumOutZ{r in Roh, i in Zulieferer, t in Periode} := sum {j in Hersteller}
rohTranMenge[r,i,j,t];
thanks a lot
