An integrated decision model of restoring technologies selection for engine remanufacturing practice

There have been various restoring technologies in remanufacturing industry for the recovery of designed dimension. The life cycle environmental performance, economic benefits, and quality reputation of remanufactured products are influenced by the restoration process. An appropriate selection of restoring technology would enhance the sustainability and assure the quality requirement of remanufactured products. The primary objective of the present study is to develop an effective and comprehensive multi-criteria decision-making approach for the application to the remanufacturing process considering the environmental impact, economic cost, and technical property. We applied the fuzzy Technique for Order Preference by Similarity to Ideal Solution (TOPSIS) approach to select a proper restoring technology for the crankshaft remanufacturing. The final results indicated that, based on the proposed criteria, the preferential ranking is brushing electroplating, plasma spray, plasma arc surfacing, and laser cladding. The present study would help facilitate and guide the selection of restoration technology in engine remanufacturing practice and benefit remanufacturers for the sustainability improvement.
