Some preference involved aggregation models for basic uncertain information using uncertainty transformation. Journal of Intelligent & Fuzzy Systems, 39(1), 325-332. https://doi.org/10.3233/JIFS-1911061875-8967 (Electronic)10.3233/JIFS-191106https://academica-e.unavarra.es/handle/2454/39497In decision making, very often the data collected are with different extents of uncertainty. The recently introduced concept, Basic Uncertain Information (BUI), serves as one ideal information representation to well model involved uncertainties with different extents. This study discusses some methods of BUI aggregation by proposing some uncertainty transformations for them. Based on some previously obtained results, we at first define Iowa operator with poset valued input vector and inducing vector. The work then defines the concept of uncertain system, on which we can further introduce the multi-layer uncertainty transformation for BUI. Subsequently, we formally introduce MUT-Iowa aggregation procedure, which has good potential to more and wider application areas. A numerical example is also offered along with some simple usage of it in decision making.8 p.application/pdfeng© 2020 – IOS Press and the authors.
