Abstract
Qiyas et al. (Int J Fuzzy Syst, 22: 310–320, 2020) proposed a linguistic picture fuzzy number (LPFN), an approach for comparing linguistic picture fuzzy numbers (LPFNs), some operational laws on LPFNs and a linguistic picture fuzzy weighted averaging (LPFWA) operator. In this commentary, some flaws that exist in Qiyas et al.’s approach for comparing LPFNs, Qiyas et al.’s operational laws and Qiyas et al.’s LPFWA operator have been pointed out.
