Since the first mobile phone for civilian use was invented in 1973 by Martin Cooper, mobile phones have become essential for daily life and they have been most commonly manufactured. The use of mobile phones and their upgrading speed have been increasing rapidly in recent years.
In addition, the product life cycle of a mobile phone has reduced considerably and its service life is currently in the range of three years. Thus, e-waste from end-of-life (EOL) mobile phones (hereinafter referred to as e-waste) is increasing two to three times faster than that from other products.
Primary constituents of e-waste from end-of-life (EOL) mobiles are glass, metal and plastic. Thus, the quality of e-waste recycling is dependent upon individual indicators like plastic recycling and recovery of metals which in turn are dependent upon various other attributes.
The problem of comprehensively evaluating quality for each system in a set of similar EOL mobile phone recycling systems has not been addressed in the literature.
Ri Ji Hye, a researcher at the Faculty of Management of Industrial Economy, has proposed a method for accomplishing this objective by using Multi Attribute Global Inference of Quality (MAGIQ) technique.
The results of the case studies showed that the application of this technique can provide decision makers with a clear picture on the quality of various recycling systems under evaluation.
