Review on remanufacturability evaluation of retired products

The uncertainty of recycling waste products affects the remanufacturing of products. Therefore, whether waste products can be remanufactured has become a key issue. Remanufacturability evaluation is an important part of the remanufacturing process of waste products, which directly determines the service safety and reliability of remanufactured products. Based on the research and review of a large number of literatures, this paper studies the current research hotspots and main research achievements of remanufacturing evaluation, and summarizes the existing achievements from the aspects of evaluation objects, evaluation directions and evaluation methods. Through research, it is found that most of the remanufacturability currently selects economic, technical, environmental and other evaluation grades, constructs corresponding evaluation index system, assigns weight to each index, and finally obtains evaluation conclusions through hierarchical analysis and entropy method.
