Multiattribute decision making is an important part of the decision process for both individual and group problems. We incorporate the fuzzy set theory and the basic nature of subjectivity due to ambiguity to achieve a flexible decision approach suitable for uncertain and fuzzy environments. Let us consider the analytic hierarchy process (AHP) in which the labels are structured as fuzzy numbers...

This paper introduces uncertainty theory to deal with non-deterministic factors in ranking alternatives. The uncertain variable method (UVM) and the definition of consistency for uncertainty comparison matrices are proposed. A simple yet pragmatic approach for testing whether or not an uncertainty comparison matrix is consistent is put forward. In cases where an uncertainty comparison matrix is...

In evaluating construction investments, public or private sector owners often have several project alternatives, e.g. different sites for development and different types of building. Assessing each of them so as to identify the best for implementation is owners’ most important decision in the project planning stage. The traditional net present worth method has difficulty in including intangible...

Application of Data Envelopment Analysis (DEA) as a Multicriterion Decision Making (MCDM) methodology is tested for Sri Ram Sagar Project, Andhra Pradesh, India to select the suitable irrigation planning alternative. Three different criterion functions of DEA, namely minimizing deviation variable D j (Min D j ), minimizing maximum deviation (Minmax), and minimizing the sum of deviations ∑ D j (...

A new method, the paired-comparison ranking technique, is proposed for assisting with internship selection decisions. This technique is discussed in terms of its ability to minimize the effects of decision frames (cf. D. Kahneman & A. Tversky, 1984) as internship sites are selected. The technique is also compared with M. C. Jacob's (1987) internship decision grid. The paired-comparison ranking ...

Ranking alternatives is an important issue in multiple criteria decision analysis (MCDA); especially that different approaches produce different results. This paper proposes a measure of relative distance, which involves the calculation of the relative position of an alternative between the anti-ideal and the ideal for ranking. In this case, minimizing the distance to the ideal is equivalent to...

Motivated by applications to crowdsourcing, we study voting rules that output a correct ranking of alternatives by quality from a large collection of noisy input rankings. We seek voting rules that are supremely robust to noise, in the sense of being correct in the face of any “reasonable” type of noise. We show that there is such a voting rule, which we call the modal ranking rule. Moreover, w...
