[Help-glpk] Modelisation of a subset

[esma mehiaoui]

Hello Everyone,

I need to express a set of elements for each element in a set. I had a syntax errors with the following formulation :

.MOD

set I := 1..5;

param J {i in I }>0, integer ;

set K {i in I }:=1..J[i];

.DATA

param J :=
1       1  
2       1 
3       2
4        2
5        3 ;

My objective is to define the variables  V{i in I, j in K[i] }= {V[1,1]; V[2,1]; V[3,1]; V[3,2] ;V[4,1]; V[4,2]; V[5,1] ;V[5,2]; V[5,3]}

Do you have any idea how to do this ?

Best regards

Esma
