We have found that A1 and A4 are dominated variants,
Example: Colour Films –Discarding Dominated Variants
so that we can overpass them. As the maximin method requires common scale for all criteria we transform the decision matrix according:
| Variant | f1 | f2 | f3 | f4 | f5 |
| 2. |

The line minima are:
A2: 0.882
A4: 0
Maximum of these minima is 0.882, so we chose the
variant A2.
