Aplikasi Himpunan Lembut Kabur Hesitant dalam Masalah Pengambilan Keputusan dari Suatu Kelompok dengan Banyak Kriteria (Studi Kasus: Pemilihan Mobil Baru Bagi Konsumen)

Abstract

Soft sets have been regarded as a useful mathematical tool to deal with uncertainty. In recent years, many scholars have shown an intense interest in soft sets and extended standard soft sets to intuitionistic fuzzy soft sets, interval-valued fuzzy soft sets, and generalized fuzzy soft sets. In this paper, hesitant fuzzy soft set is defined by combining fuzzy soft set with hesitant fuzzy set. Then, some operations on hesitant fuzzy soft set based on Archimedean t-norm and Archimedean t-conorm are defined. Besides, four aggregation operations, such as the HFSWA, HFSWG, GHFSWA and GHFSWG operators, are given. Based on these operators, do decision on the selection of new car for consumer.
