Notice: Variant a1 is better or equal in criteria 1,2,3 than variant a2. Not in all criteria! Variant a2 is better or equal in criteria 4,5,6 that variant a1. Not in all criteria! (Supposing all maximising criteria.) We say a1 and a2 are elements of nondominated set of variants or a1 and a2 are nondominated.
This graph has been easily made by Excel.
