Kano model and weighted rating evaluation method for product lifecycle improvement

Abstract

Product end-of-life is a stage in the life cycle, whereby it has inspired all form of markets in today's modern era. Manufacturer and companies are adhering to each of the available resources into seeing how to enhance and lower the natural effects of their product end-of-life. On the other side, various products have been produced without the concern of their product end-of-life, which have cause the increasing in waste products. Landfill dumps demonstrate of the way that squanders these issues to a further extend, as solid waste transfer by means of landfilling is becoming more difficult because most of the landfills are approaching its threshold or had exceeded its maximum limit of capacity. Also, lack of product recovery knowledges and recyclability features may lead to the increasing value of waste. Thus, sustainable awareness aspects must be implemented into designs, as the percentages of disposal and materials waste can be reduced significantly. Additionally, the implementation through the combination methods of Kano Model and weighted rating evaluation is one of the ways that aid consumers or manufacturers to increase the level of recycling activities. Subsequently, these combinations can also be used as a basis for consumers and manufacturers to determine on which of the products to be produced are of a good quality as well as an excellent recycling property. Therefore, this research emphasizes on the portable household fan, which has been chosen as the case study in evaluating the product end-of-life cycle.
