Hello,

 

I only recently started working with Cplex and i have some questions about tuples.

 

I connected the Data from the excel sheet to the tuple arc. 

I need for the following constraint the values from the tuple arc:

S[ j ] - S[ i ] >= sigma[ i ][ j ]

 

For S[ j ] i need the data from column B, for S[ i ] from column A and sigma[ i ][ j ] from column C.

 

I don't know how to do this. Is this possible to do?

 

.Mod

 

.data

 

Excel

 

I read the documentation but it is too general and I cannot find solutions for my specific problem.

 

Many thanks in advance!!

 

Kind regards

Try

forall(<i,j,sigma> in Arcs) S[j]-S[i]>=sigma;
