Interval-valued hesitant fuzzy set (IVHFS), which is the further generalization of hesitant fuzzy set, can overcome the barrier that the precise membership degrees are sometimes hard to be specified and permit the membership degrees of an element to a set to have a few different interval values. To efficiently and effectively aggregate the interval-valued hesitant fuzzy information, in this pap...

Methodology for Designing a Fuzzy Resolver for a Radial Distribution System Fault Locator. (December 2005) Jun Li, B.Eng.; M.Eng., Xi’an Jiaotong University Chair of Advisory Committee: Dr. Karen L. Butler-Purry Dr. B. Don Russell The Power System Automation Lab at Texas A&M University developed a fault location scheme that can be used for radial distribution systems. When a fault occurs, the s...

We study the problem of decision making with Dempster-Shafer belief structure. We analyze the previous work developed by Yager about using the ordered weighted averaging (OWA) operator in the aggregation of the Dempster-Shafer decision process. We discuss the possibility of aggregating with an ascending order in the OWA operator for the cases where the smallest value is the best result. We sugg...

n-Dimensional fuzzy sets are a set extension where the membership values n-tuples of real numbers in unit interval [0,1] increasingly ordered, called n-dimensional intervals. The intervals is denoted by Ln([0,1]). This paper aims to investigate semi-vector spaces over weak semifield and aggregation functions concerning an admissible order on construction Ln([0,1]) based operations spaces. In pa...

The paper aims to develop an adjustment index based on OWA operators to enrich the results of diagnostic fuzzy models of business failure. A proposal to verify the diseases prediction accuracy of the models is also added. This allows a reduction of the map of causes or diseases detected in strategic defined areas. At the same time, these key areas can be disaggregated when an alert indicator is...

Iran is one of the flood-prone areas in world with inappropriate climatic patterns. In this study, flood risk maps three scenarios by combining Analytic Hierarchy Process (AHP), Analytical Network (ANP) and Fuzzy (FAHP) models Ordered Weighted Average (OWA), Linear Combination (WLC) models., Local (LWLC) two new models, Multi-Criteria Analysis (WMCA) Geo Technique for Order Preference Similarit...

The ordered weighted averaging (OWA) operator is one of the most used techniques in operator’s aggregation procedure. This paper proposes a new assignment algorithm by using OWA and different extensions it Branch-and-bound algorithm. process based on use average distance (OWAD) induced OWAD (IOWAD). We present as with (BBAOWAD) IOWAD (BBAIOWAD). main advantage this approach that we can obtain m...
