Idea metody BIPOLAR polega na tym, że warianty decyzyjne nie są porównywane bezpośrednio ze sobą a z zestawami rozwiązań wskazanych jako referencyjne. Takie porównanie umożliwia sprawdzenie czy istnieją przesłanki do uznania danego wariantu za mający przewagę nad każdym z pozostałych. Zbiór rozwiązań nazywa się zbiorem punktów referencyjnych, który zawiera rozwiązania dobre i złe. Metoda BIPOLAR uwzględnia wszystkie etapy procesu decyzyjnego: wybór kryteriów oraz określenie ich wag, modelowanie preferencji decydentów, wybór właściwego wariantu decyzyjnego na podstawie rankingu.

Bipolar is one of the Multiple Criteria Decision Analysis (MCDA) methods, proposed by E. Konarzewska-Gubała. The main idea of the analysis in the Bipolar method consists in a fact that alternatives are not compared directly to each other, but they are confronted to the two sets of reference objects: good and bad. Some alternatives can be evaluated as over good, i.e. better than at least one of desirable reference object or underbid, i.e. worse than at least of one nonacceptable object. Proposed method takes into account all stages of the decision-making process, starting with the selection of criteria and determining their weights, by modeling the preferences of decision-makers, on obtaining recommendations in the form of a ranking of decision-making variants. The BIPOLAR method has been used to select suppliers of food products for retail stores. Comparison of decision variants with a reference set is carried out on similar principles as in the ELCTRE method, in which the basic principle is to compare each variant with all others. Such a comparison makes it possible to check if there are grounds for considering a given variant to have an advantage over each of the others.
