I'm searching for books on Multi-Commodity Minimum Cost Flow Problems (MCMCF) with theoretical aspects (solvability, optimality conditions, similar statements like in the case of Min Cost Flow,...). Most of the sources I found don't consider any theoretical aspects - starting with the definition of (MCMCF) they go on with solution methods.
Can you recommend good books (or the like) to me?
Thank you in advance!
This is a great introduction to flows and there is a chapter on multi commodity flows.
