Abstract

Abstract How to maximize the use of remanufactured parts with variable quality grade and improve the precision of reassembly (remanufacturing assembly) is the key to reassembly quality control. Firstly, based on analyzing the characteristics of reassembly for complex mechanical product, an assembly process control method of remanufactured product with different quality grade is proposed. Optimization model of reassemble scheme was constructed, which can describe the transmission process and the status of assembly precision in each assembly station, and characterize the relationship between assembly precision and remanufactured parts with various quality grades. Then, the solution is given by genetic algorithm, which can respond to abnormal quality situation during reassembly process and realize optimal control for reassembly process. Finally, a quality control of a prototype system for the remanufactured engine assembly is developed, which shows the feasibility and validity of the proposed method.
