WASPAS Method

Abstract

The Weighted Aggregates Sum Product Assessment (WASPAS) method was introduced by Zavadskas, Turskis, Antucheviciene, and Zakarevicius in 2012 (Zavadskas et al. in Technol Econ Dev Econ 1:131 (2013) [93], Zavadskas et al. in Sustainability 7:15923 (2015) [94], Zavadskas et al. in Acta Montan Slovaca 21:85 (2016) [95], Zavadskas et al. in Arch Civ Mech Eng 16(1):76 (2016) [96]). This method is a combination of Weighted Sum Model (WSM) and Weighted Product Model (WPM) (Zavadskas et al. in Elektron Elektrotech 122:3 (2012) [97]) . Thus, the relative importance of each attribute is simply determined, and then, the alternatives are evaluated and prioritized. This technique is applied in the personal selection (Bagocius et al. in J Civ Eng Manag 20:590 [98], Karabasevic et al. in BizInfo (Blace) J Econ Manag Inf 7:1 (2016) [99], Urosevic et al. in Cybern Stud Res 51:75 (2017) [100]), analysis of machining processes (Madic et al. in J Prod Eng 17:1 (2014) [101], Prasad et al. in Cogent Eng 5:1 (2018) 102], and material selection (Petkovic et al. in Appl Mech Mater 809:1468 (2015) [103], Yazdani et al. in Eng Econ 27:382 (2016) 104]).
