Multi-criteria Economic Analysis of Machining Processes Using the Waspas Method

The selection of the most suitable machining process for a given machining application is not straightforward and requires consideration of a number of techno-technological and economic criteria. Therefore is often viewed as a multi-criteria decision making (MCDM). This paper is focused on multi-criteria economic analysis of various machining processes by applying recently developed MCDM method, i.e. weighted aggregated sum product assessment (WASPAS) method. By using available data from literature MCDM model consisting of eight different machining processes and five economical criteria was defined. In order to determine relative significance of considered criteria a pairwise comparison matrix was applied.
