The core of the work involves the hybridisation of a number of classical MADM methods to suit decision making in the product life extension domain. The model provides a comprehensive view of the economic implications, technical requirements and environmental effects of using one of the five identified lifecycle-extension-processes (PLETs): repair, refurbishing, remanufacturing, upgrading and cascading, to elongate the service life of a given hardware. The PLETS model is intended for the evaluation and screening of PLETs, and for the selection of the best option under a given scenario. The results obtained for the shelling machine used to illustrate the applicability, and to validate both the methodology and its companion demonstrative computer implementation prototype showed that repair is the best PLET under the given conditions. The compatibility of this result with what obtains in practice shows that the methodology is a suitable decision making aid for product life extension.}, subject = {Produktlebenszyklus; Verl{\"a}ngerung; Methode}, language = {en} }
