Graph 3.1 is a graph displays the extent to which each reference DMU has in determining the
efficiency rating given to the displayed DMU in the Reference Contributions panel. The
contribution by each reference DMU to each input or output comparison is displayed as a
percentage. This graph can help us to judge the information provided by the reference
comparison panel. If a DMU had little influence in it’s rating, then it is probably not a good
reference DMU to compare the inefficient DMU with. However, if such a reference DMU has
great influence on just one or two inputs or outputs, then it can prompt investigation of those
aspects. The Graph 3.1 show Maxis is a better reference DMU to Astro.
