Copeland background and Demo
The Copeland-index is derived from the sum of the rows of the outranking matrix:
Let x,y be any two objects of an object set X, with
and the k attributes.
Let furthermore be the set of weights, then:
The outranking matrix out(x,y) is obtained summing over all
Finally C(x) is obtained as a row sum of the out(x,y) matrix:
For the objects x a weak order can be obtained due to the C(x) - values.
