Interval pairwise comparison matrices are widely accepted for practical decision making problems when the maker is unable to provide an exact judgment on alternatives. However, as measuring preference consistencies in important, this paper proposes a new interval matrix consistency measure, average geometric index, that assumes given follows lognormal distribution. This measure accounts boundar...

There are various methods for obtaining the preference vector of pair-wise comparison matrix factors. These methods can be employed when the elements of pair-wise comparison matrix are crisp while they are inefficient for fuzzy elements of pair-wise comparison matrix. In this paper, a method is proposed by which the preference vector of pair-wise comparison matrix elements can be obtained even ...

This paper surveys the progress made on pairwise orthogonal wavelet frames and comments on the construction methods. There are a few known constructions based on the unitary extension principle, a paraunitary matrix and a given modulation matrix. A polyphase matrix based construction method has been presented which satisfies the condition of unitary extension principle yielding pairwise orthogo...
