摘要

专家在决策过程中的作用至关重要。如果我们请专家帮助我们做决定，我们会假定他们是诚实的。但如果专家不诚实呢？那么，专家在特定的决策过程中提供受操纵数据的难度就变得至关重要。在本文介绍的工作中，我们考虑的是如何操纵通过几何平均法获得的排序，并将其应用到成对比较矩阵中。更具体地说，我们提出了一种算法，用于寻找一种几乎最优的方法来交换两个选定备选方案在排名中的位置。我们还定义了一个新的指数，用于衡量在给定情况下这种操作的难度。

Almost optimal manipulation of pairwise comparisons of alternatives

The role of an expert in the decision-making process is crucial. If we ask an expert to help us to make a decision we assume their honesty. But what if the expert is dishonest? Then, the answer on how difficult it is for an expert to provide manipulated data in a given case of decision-making process becomes essential. In the presented work, we consider manipulation of a ranking obtained by the Geometric Mean Method applied to a pairwise comparisons matrix. More specifically, we propose an algorithm for finding an almost optimal way to swap the positions of two selected alternatives in a ranking. We also define a new index which measures how difficult such manipulation is in a given case.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
