چکیده
|
Computationally, selection of a proper numerical value for infinitesimal non archimedeanepsilon in dea models has some difficulties. although there are several algorithmsfor selecting the proper non-archimedean epsilon, it is important to introduce methods in order to calculate the efficiency of dmus without using epsilon. one of these methods is a two-phase method, which obtains the efficiency of each dmu through solving two lps, which the second lp is depended to the first. this paper proposes a method, which is able to compute the efficiency of dmus by two lps,which are not depended to each other and computationally can solve in a parallel computation. the major of this method is to find two references for each unit and combine them to obtain actual reference.
