Efficiency assessment using slacks-based model with integer interval data

In this work, we present and comment some results from our recent paper [۷] on efficiency on slacksbasedDEA problem with integer interval data. To this matter, a new approach consisting of two phases isproposed, considering integer interval arithmetic and partial orders. The new method is illustrated andapplied to a dataset from the literature.
