The heightened risks and opportunities posed by climate change call for increased attention by business executives to employ creative and rigorous methodology in generating strategic response options. Because climate change is influenced by an assortment of multiple and interdependent variables,...

Fuzzy multi-criteria decision-making (MCDM) methods and problems have increasingly been considered in the past years. Type-1 fuzzy sets are usually used by decision-makers (DMs) to express their evaluations in the process of decision-making. Interval type-2 fuzzy sets (IT2FSs), which are...

By using the methods of multi-criteria analysis it is possible to make decisions which have significant influence on companies' business. The aim of this paper is to evaluate different suppliers using the integrated model that recognizes a combination of fuzzy AHP (Analytical Hierarchy Process)...

Consistency ratio (CR) is a very important indicator for achieving the reliability of an individual’s pairwise comparisons in Analytic Hierarchy Process (AHP). Although the applications of fuzzy AHP need this kind of CR results as well, only a few of studies include these results. The most...

Decision problems, which include multi criteria that are conflicting and take both qualitative and quantitative values, multi-criteria decision-making approaches are effective for process modeling and achieving a solution. Decision process which has more than one decision maker is called group...

Sum of Ranking Differences is an innovative statistical method that ranks competing solutions based on a reference point. The latter might arise naturally, or can be aggregated from the data. We provide two case studies to feature both possibilities. Apportionment and districting are two...

Simple additive weighting is a well-known method for scoring and ranking alternative options based on multiple attributes. However, the pitfalls associated with this approach are not widely appreciated. For example, the apparently innocuous step of normalizing the various attribute data in order...

Analytic Hierarchy Process (AHP) is one of the most popular multi-attribute decision aid methods. However, within AHP, there are several competing preference measurement scales and aggregation techniques. In this paper, we compare these possibilities using a decision problem with an inherent...

In the history, the different methods of economic production have been introduced as the dominant method. All of them have a start time, peak time, and wane time and finally, left scene for another method. Today, we live in an era that the knowledge-based economy is introduced as a dominant...

Purpose – This paper aims to propose an integration of the analytic hierarchy process (AHP) and data envelopment analysis (DEA) methods in a multiattribute grey relational analysis (GRA) methodology in which the attribute weights are completely unknown and the attribute values take the form of...
