Hey Guys,

I am currently stuck wtih my single source-sinlge destination problem.

I would like to transform the model, that it uses all origings and destinations in my excel file and calculations for each "Travel Event" the current shortest path. I tried it many times but only got errors.

I attached my Xpress model und my Excel data base.

Maybe someone could help me here.

Question 1: How can I transform it to a multi source - multi destination and save everything in the correct fields in excel

Question 2: Is the any possiblity to write for every travelevent the exact path (as it already exists in my output data) in my excel sheet?

It would be a great help

Thanks

Sebastian

Regarding the output, it might help to create a 'list' of each path and write out this list (on the topic of list handling in Mosel, see for example FICO Xpress Optimization Examples Repository: Eulerian circuit - working with lists ).

Here are a few links to example models of network flow problems with several origins and destinations:
