Quantifying the Quality Grade of the Return Mobile Phone

Abstract

Products including garments, clothing accessories, and consumer electronics are prone to suffer from short product life cycles as a result of fast technological advancements, manufacturers' marketing methods, and rapidly changing customer tastes. With the growing demand for the technology-driven product, the mobile phone's lifespan has fallen to three to six months. To compete with the global market, the mobile manufacturer cut down the price of mobile phones and provides upgraded specifications. For this reason, consumer wants to experience the new technology in every instance and exchange their mobile phone for a newer one. The performance of the mobile phone does not reduce, but to upgrade to modern technology, the customer intends to swap it with the fresh one. For this purpose, a circular economy comes into the picture. Remanufacturing is becoming a critical element of a circular economy where products are created, produced, used, and retrieved to avoid any kind of waste and decrease the extraction of raw materials. However, lots of studies are carried out on the quality grading of the returned core, but we did not find any of the quantified definite indexes for the quality of the yielding core. Thus, in these articles, we attempt to quantify the quality of returned core (mobile phone) by using MCDM and PCA / FA methods. Finally, the reduction equation is established to predict the quality of returned core, which reduces the remanufacturing cost by providing optimal shorting.
