Use of Lp Metric for Ranking Alternatives

The ranking of alternatives is done by calculating the ly metric between the ideal solution (I) and each vector representing an alternative s ratings for the criteria. The ideal solution represents the best values possible for each criterion. Because no alternative will have the best values for all the criteria (e.g., a supplier with minimum cost may have poor quality and delivery hme), the ideal solution is an artificial target and cannot be achieved. The Lp metric approach computes the distance of each alternative s attributes
