Ranking all units efficient with SBM proposed method

In this paper a new method based SBM model with slacks variables free in sign, all of the for ranking efficient units that can provide non-extreme ranking the efficient units, It also does not have the problem of instability and infeasible.This model specifies the largest MPSS and other units into a unit image. Then, using examples MAJ, CHEN, CSW, AP, and MAJ modified Khodabakhshi methods will be compared
