Evaluation of human resource information systems using grey ordinal pairwise comparison MCDM methods

This paper evaluates the human resource information systems provided by different vendors using two new hybrid multicriteria decision-making methods that require ordinal data as inputs. First, the grey-point-allocation full-consistency (Grey-PA-FUCOM) weighting method is proposed. The Grey-PA-FUCOM combines the simple point-allocation method widely used by human resource managers and the advanced FUCOM method widely accepted by scholars in grey system theory. Second, the grey-regime method, an extension of the classical regime method based on grey system theory, is used to account for the uncertainty in the evaluation. Next, the Grey-PA-FUCOM weights are applied in conjunction with the grey-regime scheme to evaluate the five vendors. Finally, to validate the results of this study, grey relational analysis with grey numbers, the grey weighted sum model, and a technique for order performance based on the similarity to the ideal solution with grey values are used.
