Development of an AHP-CBR evaluation system for remanufacturing: End-of-life selection strategy

This paper presents our research works on developing an evaluation system for remanufacturing. This paper has two objectives. The first objective is to evaluate the product end-of-life (EOL) by integrating an analytical hierarchy process (AHP) with case-based reasoning (CBR). The nearest neighbourhood (NN) algorithm was used to retrieve a past case that is closest to the current case under consideration. The AHP, which allows the pair-wise comparison and consistency judgement, was used to determine the weight in NN. The second objective is to evaluate EOL of parts and components. The integration of an economical cost model and an environmental cost model was used to determine the EOL of parts and components. An example is presented and discussed. The predicted results of the complete method were compared with those of the previous study. The results showed that the integration of the AHP-CBR method has reached a good correspondence with the established methods.
