With the rest of so it report are structured as follows: within the “Literature remark” point evaluations the new books; within the “Notation and you may presumptions” point relates to the notations and you will assumptions; inside the “Design elements” area defines the fresh statistical model on about three instances of the newest ACC fee program to have upstream credit months by the a merchant in order to a store, plus in “Theoretic overall performance and algorithm and you may Computational analysis” parts, respectively, establish new theoretic and you may computational results with managerial knowledge into the later. Finally, the conclusion and you can testimonial was shown into the “Conclusion” section.
