Remanufacturing scheme decision model and application based on reliability evaluation

摘要

With the elimination rate of mechanical products is getting higher and higher, it has become a huge problem for manufacturing enterprises to resourcefully dispose the used mechanical products. In order to optimize the resource utilization of the used components, a decision-making model for determining the appropriate remanufacturing plan was established from the perspective of the component reliability based on historical life data. In this study, the three-parameter Weibull distribution function was used to evaluate the component reliability, and the degree of reliability was computed quantitatively. The appropriate remanufacturing plan for the used component was then determined by combining the degree of reliability with the remanufacturing reliability threshold values provided by the manufacturer. The feasibility of the presented model was verified by applying the model to the failure of the bearing on the transfer case. This study can provide technical support for the research and application on remanufacturing scheme decision-making models and active remanufacturing technology of the used components.
