Possibility Degree Method for Trapezoidal Fuzzy Numbers and Its Application in Logistics Park Location

Mei Li, Chong Wu, Nannan Li, Yanrong Hu

Abstract


This paper presents a possibility degree formula for the comparison between two trapezoidal fuzzy numbers and some operational laws. Some desirable properties are studied in detail based on those operational laws. Based on these possibility formulas, a possibility degree method for Trapezoidal fuzzy numbers is also given and it is used to rank the alternatives in uncertain multi-attribute decision making. The study is developed by taking the example of location of logistics park.

Keywords


trapezoidal fuzzy numbers, possibility degree, ranking.
