5. Conclusions
This paper re-examines the cost sharing problem studied in [3] and proposes the AMEF value, a new allocation rule for inventory transportation systems. Those systems assume that agents are located on a line route. An interesting generalization follows if that assumption is dropped and a more general spatial assumption is made instead (like, for instance, that agents are located on a tree rooted in the supplier). We plan to deal with this kind of generalized model in the future.
