Knowledge graph-based approach to trace the full life cycle information of decommissioned electromechanical products.

Aiming at the problems of high spatial and temporal dispersion, strong quality uncertainty and weak cross-organizational information correlation in the recycling of decommissioned electromechanical products, this paper proposes a knowledge graph-based method for tracing the full life cycle information of decommissioned electromechanical products. First, the structure of the knowledge graph of the full life cycle information of decommissioned electromechanical products is constructed, then the key techniques for constructing the knowledge graph of the full life cycle information of decommissioned electromechanical products are proposed, and finally, the effectiveness of the method is verified through examples, which can provide strong support for the full life cycle information tracing of decommissioned electromechanical products.
