Determining units Ranking with the Best and the Worst Rank of Each unit as well as Interval Ranking.

Abstract

In this paper, we did unit ranking by determining the best and the worst rank that each unit could have. By applying the optimistic Model, we determine the best rank of each unit, then by using the Pessimistic model, we determine the worst rank of that unit. The highest rank of each unit is displayed by r°b and the lowest rank is displayed by r°w.
