A problem of the inconsistency of pairwise comparisons is of focal interest in the analytic hierarchy process (AHP), but, up to date, we know only little about how much are real decision makers inconsistent, and whether the number of objects to be compared influences the inconsistency.Expand

The rough set theory, which originated in the early 1980s, provides an alternative approach to the fuzzy set theory when dealing with uncertainty, vagueness or inconsistence in real-world situations.Expand

We propose a new quantitative recession magnitude scale for measuring recessions' magnitudes ('strength') derived from GDP growth rates during a recession and its duration. Furthermore, we introduce… Expand

In ordinal ranking problems objects, alternatives, products, services, etc. are ranked by several experts and the goal is to convert a set of (generally different) rankings into the final group… Expand

We show a relationship between inconsistency in the pairwise comparisons method and conditions of order preservation based on the properties of elements of alo-group.Expand

In this paper, a new categorization of inconsistent pairwise comparisons matrices is proposed with respect to the satisfaction/violation of selected logical properties, such as the fundamental selection (FS) condition, the preservation of order preference (POP) and the Preservation of order of intensity of preference (POIP).Expand

Pairwise comparisons are an important tool of modern (multiple criteria) decision making. Since human judgments are often inconsistent, many studies have focused on the means of expressing and… Expand
