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.

When new technologies become available and cultures adopt them, the result can be either convergence, cultures becoming more similar as a result, or divergence, when cultures adopt technology in different ways that maintain or even further accentuate their differences. An analysis of full‐service national Web portals from different countries, typically offering a search engine, directories of links on a set of selected topics, news items (including weather, sports, entertainment, and stock market results), advertisements and shopping, and free e‐mail, shows evidence of both trends. While most national portals closely resemble the basic structure of Yahoo!, the original free full‐service portal, there are also differences in appearance and features offered that can be attributed to cultural variations based on Hofstede’s framework.
