An Approach to Determine the Attribute Weights Based on Different Formats of Evaluation Information

摘要

This paper proposes an approach to determine attribute weights in the multiple attribute comprehensive evaluation (MACA) problem, in which the attribute values of alternatives are expressed in three formats of evaluation information such as real number, interval number and fuzzy linguistic term. In the approach, an optimization model is constructed to determine attribute weights, which makes the obtained attribute weights reflect the original evaluation information. An example is used to illustrate the applicability of the proposed approach.
