A manager of a manufacturing plant is looking for a new vertical machining center and currently studying three different manufacturers of DMG Mori Seiki, FANUC, and Mazak. Their machining centers vary in terms of price, CNC, and plant-wide connectivity. The following pairwise comparison matrixes (Table 4 7) were developed:

1. What are the priorities for each pairwise comparison matrix?

b. Determine the overall priority for each manufacturer and define which manufacturer is preferred.
