Following decision contains attributes of 6 colour film evaluated by:

1. Price (CZK)
2. Sensitivity – real, measured (ISO)
3. Possibility of overexposure (exposure grades)
4. Possibility of underexposure (exposure grades)
5. Resolution of lines (number of lines per 1 mm)

1. Absolute Dominance

If any real variant is equal to negative ideal variant D i.e. all it‘s attributes are equal to column minimal values if all criteria are maximal that is not this case (the price is minimal criterion).



As follows from the table above, no real variant is equal to negative optimum.
2. Pairwise sequential comparison

• Compare first two alternatives and if one is dominated by other, discard the dominated one.
• Compare the undiscarded alternatives with third alternative and discard any dominated alternative
• The nondominated set is determined after (m-1) comparisons

1. compare: A1 and A2

A1 is dominated by A2; A1 did not pass to following comparison
2. compare: A2 and A3 – no dominance
3. compare: A2 and A4
