Open publisher page 0 citations

Abstract

The DMU with inputs increased,and its efficiency level became r times to primal level, how much more outputs could the unit produce,such problem was called r-inverse DEA problem in this paper.It is the extension of general inverse DEA problem.By constructing two special linear programming models,an approach to get a kind of solution for r-inverse DEA problem had been ob- tained,with the illustration by a numerical example.
