Review on DEA models involving the non-Archimedean infinitesimal

Charnes et al.introduced the first DEA model in 1978.The model does not involve the non-Archimedean infinitesimal.Charnes et al.introduced the non-Archimedean infinitesimal to DEA models and constructed the DEA model involving the non-Archimedean infinitesimal in 1981.There have been debates about the DEA model involving the non-Archimedean infinitesimal and the debates continue to this day.The debates mainly focus on two points.One is the existence of the DEA model involving the non-Archimedean infinitesimal itself,and the other is the method of how to solve such a DEA model.This paper is a review containing the above two respects about the DEA model involving the non-Archimedean infinitesimal.
