  The aim of this paper is to present a novel approach for ranking of all DMUs
using the interval Cross-Efficiency (ICE) and interval Analytic Hierarchy
Process (IAHP) methods. The approach includes two basic stages. In the first
stage using DEA models the interval cross-efficiency values of each DMU are
specified. In the second stage, the interval pairwise comparison matrix
generated in the first stage is utilized to rank the units (DMUs) via the one
step process of interval AHP (i.e. the AHP model with interval decision maker
judgements). The numerical example is presented in this paper and we compare
our approach with some other approaches.
