In decision making, situations where all experts are able to efficiently express their
preferences over all the available options are the exception rather than the rule. Indeed, the …

Multi-person decision making problems involve the preferences of some experts about a set
of alternatives in order to find the best one. However, sometimes experts might not possess …

This note analyzes two methods for calculating missing values of an incomplete reciprocal
fuzzy preference relation. The first method by Herrera-Viedma appeared in the IEEE …

Preference Relations are a popular and powerful tool used by decision makers to provide
their preference information in the process of decision making. Over the last decades …

In this paper, we present a procedure to estimate missing preference values when dealing
with pairwise comparison and heterogeneous information. This procedure attempts to …

Decision situations with incomplete information are characterized by a decision maker
without a precisely defined, stable preference structure; by probability distributions not …

Preference relations as simple and efficient information description tools have been widely
used in practical decision‐making problems. Intuitionistic preference relation, which is often …

This paper presents methods for dealing with incomplete information about both attribute
weights and values under a hierarchically structured value tree. Incomplete information in …

The philosophy of preference disaggregation in multicriteria decision-aid systems (MCDA) is
to assess/infer global preference models from the given preferential structures and to …

The aim of this paper is to present tools or techniques for an interactive multiattribute
decisionmaking with the decision maker's incomplete information. That is:(1) We formally …
