In this paper we introduce a preliminary approach for a weighting method that is intended to overcome possible biases detected in traditional weighting methods. The procedure is based on a combined application of several methods,
SWING weighting, TRADE-OFFS weighting
Direct point allocation
. It benefits from the value tree and the propagation of attribute weights through the tree to perform consistency checks and admits imprecision concerning the DM responses, whcih leads to imprecise local and attribute weights. However, the possible inclusion of other weighting methods in the process and the analysis of associated biases still needs to be analyzed.
