A new model to select fasteners in design for disassembly

Product disassembly will only take place if there is enough generated profit. But as the end-of-life is often overlooked during the design process it makes the disassembly hard to perform and therefore the profitability is especially reduced. Design for disassembly is one of proposed solutions and fasteners are one of the points that have most impact on the disassembly of products. The aim of the proposed model is to determine among several alternatives which one allows to meet the requirements in assembly, in-use, services and disassembly. The model takes into account the semi-destructive disassembly (deteriorate a part of a sub-assembly to recover valuable components or materials and while reducing the disassembly time without important value loss). The model developed in this paper is mainly based on the Analytic Network Process (ANP) to define the best alternative and make the fastener selection during the design process easily. An example is presented for a better comprehension. (C) 2016 The Authors. Published by Elsevier B.V.
