Knowledge Graph-based Customer-centric Deconstruction Assessment Model

Abstract: Demolition remains the dominant practice at the end-of-life stage, primarily due to its immediate economic advantages. Transitioning from demolition to deconstruction requires a shift in focus toward meeting customers’ needs in the second-hand market. Therefore, the present study proposes a customer-centric deconstruction assessment model to enhance deconstruction planning. The research followed a three-stage methodology: (i) analyzing the attributes of existing deconstruction models; (ii) identifying the requirements of potential customers; and (iii) developing a knowledge graph model. The proposed model, which focused specifically on wood-based products, demonstrated its practical applicability by effectively matching products with suitable customers across five test scenarios.
