Saaty’s scale application to multistage bipolar method

Multistage Bipolar Method considered in the paper deals with multistage decision processes. Multistage alternatives are not compared directly to each other, but confronted with the stage sets of reference objects—desirable and non-acceptable. The original version of the method is based on ELECTRE methodology. The aim of this paper is to present and discuss three proposals for including verbal comparisons, characteristic of the widely used AHP method, into the previously proposed procedure in MBM. In all these proposals, we propose to use Saaty’s scale to compare decision alternatives and reference objects.
