AHP QFD methodology for a recycled solar collector

As it is presented in literature, the AHP-QFD method is a method applicable to many sectors, namely industry. The article is a part of this framework, applying this method for the design of a recycled solar air heater according to customer’s expectations. The methodology is based on the application of QFD to detect consumer requirements, technical characteristics and their relationship matrices. while the AHP method aims to evaluate the weights of each criterion in order to make the right decision. In this study, the manufacturing process was projected from upstream to downstream, as well as a market study was established in October 2020, in Khouribga-Morocco, in which 50 people responded favourably to a survey about the most frequently searched requirements which include size, efficiency, design, price and ecology as well as their importance in a solar collector. Besides, relationship matrices and the weight matrices of the technical criteria have been established, by presenting a consistent ratio “CR” less than 10% showing the consistency of the assessment, and finally a priority given to the characteristics of the recycled solar air heater: cans and thermal insulation more superior to the others characteristics.
