Discuss the AHP model for selecting suppliers AND the Center of Gravity model for selecting locations for distribution centers using excel.

Hi, I have a research paper due in the next couple of days. However, this research paper has some stuff that are needed to be done in excel, so they are the AHP model for selecting suppliers AND the Center of Gravity model for selecting locations for distribution centers, both of them need excel work. So please let me know if you have someone knows how to do these two models or not. I don’t have time to waste
