Abstract

Due to the large use of fuzzy numbers, the ranking of these numbers is very important.In this paper, we propose a new method for ranking generalized fuzzy numbers with different left and right heights.The proposed method, at first obtains the centers of gravity of fuzzy numbers and left and right side crisp numbers; then by computing left and right areas associated with them, ranks the fuzzy numbers. The proposed method can overcome the flaws and defects of some ranking methods, and the provided examples are evidence of this. Finally this method is applied to the fuzzy risk analysis problem.

一种两高度广义模糊数排序的新方法及其在模糊风险分析中的应用

由于模糊数的大量使用，这些数的排序非常重要。本文提出了一种对具有不同左右高度的广义模糊数进行排序的新方法。所提出的方法，首先得到模糊数和左右侧清晰数的重心;然后通过计算与它们相关的左右区域，对模糊数进行排序。本文提出的方法可以克服一些排序方法的缺陷和缺陷，并通过实例加以验证。最后将该方法应用于模糊风险分析问题。

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.
