Additive Ratio Assessment (Aras) Method

摘要

The additive ratio assessment method is based on quantitative measurements and utility theory. In this method, a utility function value determines the relative efficiency of an alternative over the other alternatives. This utility function is directly proportional to the relative effect of the criteria values and weight importance of the considered criteria. With the rapid advancement of computational facilities, applications of advanced manufacturing technologies, mainly in the form of industrial robots, CNC machine tools, FMS, automated material handling systems, automated inspection devices, etc., have become indispensable in the modern-day manufacturing environment. With the continuous demand for highly precise machined components with higher dimensional accuracy and close tolerance, the conventional machining centers are now being replaced by the CNC machine tools.
