“…Conventional MCDM research comprises two major fields: multiple attribute decision-making (MADM) and multiple objective decision-making (MODM), as suggested by previous work (Hwang & Yoon, 1981;Liou & Tzeng, 2012;Zavadskas, Turskis, & Kildienė, 2014;Zeleny, 1982). Both MADM and MODM (or HMCDM) have enticed numerous researchers to employ suitable methods for solving problems in fields like economics (Zavadskas & Turskis, 2011), marketing (Kumar, Rahman, & Kazmi, 2013), e-learning (Zare et al, 2016), finance (Spronk, Steuer, & Zopounidis, 2016;Zopounidis, Galariotis, Doumpos, Sarri, & Andriosopoulos, 2015), construction site selection (Turskis, Zavadskas, Antucheviciene, & Kosareva, 2015), engineering , supplier evaluation and selection (Keshavarz Ghorabaee, Amiri, , supply-chain management (Ansari & Kant, 2017;Soheilirad et al, 2017) and green energy (Kumar et al, 2017). Although those studies have shown various MCDM or HMCDH approaches to decision support, three crucial issues deserve more attention.…”
