Decision-making techniques with similarity measures and OWA operators

We analyse the use of the ordered weighted average (OWA) in de cision-making giving special attention to business and economic decision-making proble ms. We present several aggregation techniques that are very useful for decision-making such as the Hamming distance, the adequacy coefficient and the index of maximum and minimum level. We sug gest a new approach by using immediate weights, that is, by using the weighted average an d the OWA operator in the same formulation. We further generalize them by using generaliz ed and quasi-arithmetic means. We also analyse the applicability of the OWA operator in busine ss and economics and we see that we can use it instead of the weighted average.
