Promethee methods: sensibility study & remarks
In the case of a decision rule based on an aggregation function that places us in the Arrow’s theorem
context, it is not possible to check some mathematical properties simultaneously. Indeed, to
construct a method using the same concepts, we can not abandon the principles of unanimity,
universality and non-dictatorship. Thus, the only two principles between which we have to choose
are the transitivity and the independence. In other words, it is impossible to build an ordinal method
verifying the transitivity and the independence at the same time. A thorough analysis has shown the
impossibility to find and\or define MCDM methods satisfying some derived mathematics properties
In this paper, we study the sensibility of Promethee family methods to the use of different versions
of independence and transitivity. On this basis, we construct rules and mathematical conditions
upon which Promethee family keep their original results. In case of change of the original
outranking, we propose post-optimality studies and enquiries allowing to expect the new results and
their values.
