[Abstract]:As one of the key development directions in the future, remanufacturing engineering is characterized by saving resources, saving energy and protecting environment. Based on the analysis of relevant research on remanufacturing engineering, this paper discusses the acquisition and expression of remanufacturing process knowledge. The intelligent decision model of remanufacturing process based on knowledge is constructed, and the case analysis is carried out, and a prototype system of intelligent decision support for remanufacturing process based on knowledge is developed with the help of Java and SQL Server. 1) the representation model and method of remanufacturing process knowledge are discussed. According to the characteristics of remanufacturing process knowledge, a remanufacturing process knowledge representation model is established. 2) the construction of remanufacturing process case base and rule base. Based on the representation of remanufacturing process knowledge, the remanufacturing process case base and rule base are established to realize the acquisition, storage, sharing and application of remanufacturing process knowledge. (3) Knowledge-based intelligent decision model of remanufacturing process is constructed, which is based on CBR (case based reasoning) and RBR-based rule reasoning (RBR), and the intelligent decision model of remanufacturing process based on knowledge is constructed by Case-based reasoning (CBR) and rule-based reasoning (RBR). 4) case study of intelligent decision making of remanufacturing process. Taking the remanufacturing of hydraulic cylinder as an example, the validity and feasibility of the above decision support model are analyzed and verified. 5) the design and implementation of a knowledge-based intelligent decision support system for remanufacturing process. A Knowledge-based intelligent decision support system for remanufacturing process is developed and implemented.
