A quality evaluation model of reuse parts and its management system development for end-of-life wheel loaders

Since many countries are paying more and more attention on environmental and sustainable issues, there are increasing requirements that promote manufacturers to environmentally and friendly collect, recover, and dispose their end-of-life products or parts. In China, a lot of parts in the wheel loader are designed with ultra high strength because of their extremely severe and harsh working conditions. Even though the whole set of equipments or the specific component is at its end-of-life, many parts can still be reused directly without further remanufacturing, which minimizes the impact on the environment. Based on the fuzzy analytic hierarchy process (AHP), a quality evaluation model is presented in this work to quantify the reusability degree of the recycling parts on the end-of-life wheel loader. The model makes a decision on whether the part is worthy to be reused directly. Meanwhile, for easier management of the recycling parts as well as convenient evaluation of their reusability, a management system of recycling process is developed with Browser/Sever structure based on the C# programming language. It includes management information functions such as inspection, evaluation, and repair during a recovery process. The main contribution of this system is helpful to strengthen the management of the whole recovery process and improve on the efficiency of workflow.
