“…In so doing we have conceived three hierarchies, not one, each of them having up to three levels, which complies with the threshold suggested by Pérez et al (2006), who considered that in more complex hierarchies, with more than three levels, rank reversal may occur.…”

Dragoi M., Palaghianu C., Miron-Onciul M., 2015. Benefit, cost and risk analysis on extending the forest roads network: A case study in Crasna Valley (Romania). Ann. For. Res. 58(2): 333-345.Abstract. The paper presents how the Analytic Hierarchy Process can be used to select the most suitable combination of new forest roads to build onto a forested area provided that social or ecological aspects are not jeopardized. All important features worth being considered when a new network of forest roads is designed were grouped in three types of criteria, which are benefits, costs and risks. Further, in order to ease the pairwise comparisons between criteria, both benefits and costs have been divided into private and social, while the risks refer to the events that might be triggered or favoured by the construction of new roads, like habitat fragmentation, landslides in case of heavy rainfall during the construction phase or even illegal cuttings. The outcome consists of a series of benefit-cost-and-risk indices and benefit-cost ratios, one for each combination of forest roads, including the status quo. The method has been tested on three combinations of new forest roads already designed for a small forest management unit located in Prahova County, encompassing 838.0 ha of mountainous forest.

“…None of these claims, however, consider whether a decision method is correct and produces better outcomes than another method, or even than no method at all (i.e.. decisions based on intuition alone). The popular AHP method [57], for example, is criticised by decision experts for its mathematical flaws [8,10,53] and lack of evidence that it leads to better decisions than intuition alone [40].…”

Uncertainty complicates early requirements and architecture decisions and may expose a software project to significant risk. Yet software architects lack support for evaluating uncertainty, its impact on risk, and the value of reducing uncertainty before making critical decisions. We propose to apply decision analysis and multi-objective optimisation techniques to provide such support. We present a systematic method allowing software architects to describe uncertainty about the impact of alternatives on stakeholders' goals; to calculate the consequences of uncertainty through Monte-Carlo simulation; to shortlist candidate architectures based on expected costs, benefits and risks; and to assess the value of obtaining additional information before deciding. We demonstrate our method on the design of a system for coordinating emergency response teams. Our approach highlights the need for requirements engineering and software cost estimation methods to disclose uncertainty instead of hiding it.

“…Perez et al . () showed that the addition of different criteria (for which all alternatives performed equally) caused a significant alteration of the aggregated priorities of alternatives, with important consequences. Although not in three‐level hierarchies, rank reversal might happen in more complex hierarchies.…”

Multi Criteria Decision Anal

View full text Add to dashboard Cite

During the last few decades, several multi‐criteria decision analysis methods have been proposed to help in selecting the best compromise alternatives. Among them, analytic hierarchy process (AHP) and its applications have attracted much attention from academics and practitioners. However, since the early 1980s, critics have raised questions regarding its proper use. One of them concerns the unacceptable changes in the ranks of the alternatives, called rank reversal, upon changing the structure of the decision. Several modifications were suggested to preserve ranks. In this paper, a classification scheme and a comprehensive literature review are presented in order to uncover, classify and interpret the current research on AHP methodologies and rank reversals. On the basis of the scheme, 61 scholarly papers from 18 journals are categorized into specific areas. The specific areas include the papers on the topics of adding/deleting alternatives and the papers published in adding/deleting criteria. The scholarly papers are also classified by (1) year of publication, (2) journal of publication, (3) authors' geographic location and (4) using the AHP in association with other methods. It is hoped that the paper can meet the needs of researchers and practitioners for convenient references of AHP methodologies and rank reversals and hence promote the future of rank reversal research.
