Comparison of decision variants with reference set (BIPOLAR method) in selection process of suppliers

subject

description

Bipolar is one of the Multiple Criteria Decision Analysis (MCDA) methods, proposed by Ewa Konarzewska-Gubała [6, 7, 8]. The essence 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 modelling the preferences of decision-makers, on obtaining recommendations in the form of a ranking of decision-making variants. In this paper case study of choosing suppliers is presented. The BIPOLAR method has been used to select suppliers of food products for retail stores.
