A Knowledge Graph-Aided Concept–Knowledge Approach for Evolutionary Smart Product–Service System Development

Abstract

In order to meet user expectations and to optimize user experience with a higher degree of flexibility and sustainability, the Smart product–service system (Smart PSS), as a novel value proposition paradigm considering both online and offline smartness, was proposed. However, conventional manners for developing PSS require many professional consultations and still cannot meet with the new features of Smart PSS, such as user context-awareness and ever-evolving knowledge management. Therefore, aiming to assist Smart PSS development cost-effectively, this paper adopted the knowledge graph (KG) technique and concept–knowledge (C-K) model to propose an evolutionary design approach. Two knowledge graphs are firstly established with open-source knowledge, prototype specifications, and user-generated textual data. Then, triggered by personalized requirements, four KG-aided C-K operators are conducted based on graph-based query patterns and computational linguistics algorithms, thus generating innovative solutions for evolving Smart PSS. To validate the performance of the proposed approach, a case study of a smart nursing bed fulfilling multiple personalized requirements is conducted, and the evaluation result of its knowledge evolution is acceptable. It hopes that this work can offer insightful guidance to industrial organizations in their development of Smart PSS.

Digital Twin Driven Requirement Conversion in Smart Customized Design

“…Beernaert and Etman [16] coordinated RC decisions that involve multiple components of a complex product by analytical target cascading. Li et al [17] adopted the knowledge graph technique and concept-knowledge model to possess the knowledge reasoning ability under multidisciplinary fields and achieve hybrid intelligence by user-generated data. Cong et al [18] proposed design context-awareness and design entropy theory to represent the process of entropy reduction in RC.…”

Industrial smart product‐service system development for lifecycle sustainability concerns

“…refurbishment of a wind turbine). More critically, in the cyber space, enabled by the advanced ICT and AI, the intangible resources of reliable dataset, annotated information and mined knowledge are also reallocated in the process of service innovation, where the valuable information/knowledge can be transferred to a new solution [5]. Furthermore, it also denotes the cyber‐physical integrated situations, where smart services (software) can replace products (hardware) to some extent (e.g.…”
