Group prioritization in the AHP by fuzzy preference programming method
TLDR
The GFPP method combines the group synthesis and prioritization stages into a coherent integrated framework, which does not need additional aggregation procedures and provides a meaningful indicator for measuring the level of group satisfaction and group consistency.About:

Review of the main developments in the analytic hierarchy process
Alessio Ishizaka,Ashraf Labib +1 more
TL;DR: This paper discusses problem modelling, pair-wise comparisons, judgement scales, derivation methods, consistency indices, incomplete matrix, synthesis of the weights, sensitivity analysis and group decisions that have appeared since its introduction.

On the invalidity of fuzzifying numerical judgments in the Analytic Hierarchy Process
Thomas L. Saaty,Liem Tran +1 more
TL;DR: Fuzzy set theory has serious difficulties in producing valid answers in decision-making by fuzzifying judgments, and improving the consistency of a judgment matrix does not necessarily improve the validity of the outcome.

A two-stage logarithmic goal programming method for generating weights from interval comparison matrices
TL;DR: A two-stage logarithmic goal programming (TLGP) method is proposed to generate weights from interval comparison matrices, which can be either consistent or inconsistent, and is applicable to fuzzy comparison matrix when they are transformed into interval comparison Matrices using @a-level sets and the extension principle.

A decision support model for sustainable supplier selection in sustainable supply chain management
TL;DR: A hybrid model is proposed to identify the most sustainable supplier with respect to the determined attributes using an Iranian textile manufacturing company as case study and the results show that economic aspect is still the most essential aspect, followed by environmental aspect and finally social aspect.
Journal ArticleDOI
Linking analytic hierarchy process and social choice methods to support group decision-making in water management
TL;DR: Two possible contexts in modeling decentralized decision problems in water management are investigated, based on AHP only and two group aggregation techniques, which are considered more promising for implementation in real-decision situations inWater management.

The Analytic Hierarchy Process
Thomas L. Saaty,Kevin P. Kearns +1 more
TL;DR: Analytic Hierarchy Process (AHP) as mentioned in this paper is a systematic procedure for representing the elements of any problem hierarchically, which organizes the basic rationality by breaking down a problem into its smaller constituent parts and then guides decision makers through a series of pairwise comparison judgments to express the relative strength or intensity of impact of the elements in the hierarchy.

Decision-making in a fuzzy environment
Richard Bellman,Lotfi A. Zadeh +1 more
TL;DR: A reverse-flow technique is described for the solution of a functional equation arising in connection with a decision process in which the termination time is defined implicitly by the condition that the process stops when the system under control enters a specified set of states in its state space.

Aggregating individual judgments and priorities with the analytic hierarchy process
Ernest H. Forman,Kirti Peniwati +1 more
TL;DR: The Analytic Hierarchy Process is often used in group settings where group members either engage in discussion to achieve a consensus or express their own preferences, and it is concluded that while this method can be useful, it is applicable only in special circumstances.

Description and optimization of fuzzy systems
TL;DR: Fuzzy set theory is applied to fuzzy linear programming problems and it is shown how fuzzylinear programming problems can be solved without increasing the computational effort.

Procedures for Synthesizing Ratio Judgements
J. Aczel,Thomas L. Saaty +1 more
TL;DR: In this article, the requirements for functions synthesizing judgements (quantities or their ratios), in particular separability, associativity or bisymmetry, cancellativity, consensus, reciprocal or homogeneity properties are investigated and all functions satisfying them are determined.
