This paper presents our continuing work to develop methods to exchange product knowledge in the semantic level in the CAD/CAE domains. We present an approach based on a shared ontology, in which a higher level of ontologies are shared among lower levels of ontologies. Key mapping strategies, such as Equivalency, Attribute Similarity, Composition Similarity, and Inheritance Similarity are defined to map concepts and properties defined in a product design domain and an assembly simulation domain. In addition, a Bridge Ontology is designed to store information obtained from mapping processes and construct a link between different knowledge repositories. An Ontology Mapping Application (OMA) which brings together all these elements has been designed and implemented. It is a Java-based application that allows the user to load source and target ontologies, calculate concept and property similarities between them, display the mapping results, and output a corresponding Bridge Ontology.

Knowledge Classification

Based on the features of distributed knowledge resources environment and taking knowledge mobility in modern design as its supporting goal, this essay focuses on research into knowledge classification systems and representation models of product design. It proposes a six-dimension design knowledge classification system and a cubic knowledge representation model operating in an environment of distributed resources. The six dimensions of design knowledge classification are discipline, product, resource unit, application process, expression pattern, and design domain respectively. Accordingly, the six planes of the cubic knowledge representation model are, therefore, the discipline plane, expression pattern plane, resource unit plane, product plane, application process plane, and design domain plane, clearly represent the application profiles of design knowledge in six dimensions. The six-dimension design knowledge classification system and cubic model are applied to fluid simulation implicit knowledge (expert knowledge) as a real case, and are the basis upon which an application system of fluid emulation expert knowledge service is developed. The design knowledge classification system and representation model proposed in this essay are the theoretical foundations for knowledge flow model development in modern product design and the construction of knowledge management systems for modern design platforms.

This is a “concept” paper. It explores the potential usages of interactive tabletops and surfaces in product design. Interactive tabletops and surfaces are a family of display technologies coupled with sensors that enable a more natural approach for interacting with computers. Previous research demonstrates the many possible uses for interactive tabletops and surfaces in design domain through several applications. This paper explores the potential of this technology to enhance the performance of designers and design groups. This paper highlights the benefits of interactive tabletops and surfaces in design through discussion of different potential applications and their possible advantages. The methodological approach for developing interactive tabletops and surfaces application for design has been presented and supported through a case study. Through the proposed approach we aim to gain a better understanding of practical challenges that need to be considered when integrating interactive tabletops and surfaces technology into a design office.

With the increasing attention on the role of consumer behavior in sustainable development, consideration of consumer’s product repair and reuse behavior is becoming more and more important in the product design domain. In order to investigate the product ease-of-repair and its effect on future product purchase and recommendation decisions made by consumers, this paper studies the main reasons that consumers were not able to repair a product based on a survey data collected by a wiki-based website that offers repair manuals for consumer electronics. Two main questions have been asked in the survey: what is the last thing you personally fixed? And why did you not succeed in fixing it. The information of these questions and the available response options have been used to compared eleven types of electronics in terms of their ease-of-repair. A list of design features (e.g. openability, accessibility, standardization, and modularity) that may increase the repair adoption by individual consumers has been discussed. In addition, a Data Envelopment Analysis (DEA) method was introduced to compare different categories of products in terms of reparability efficiency. The findings on how repair experiences or efficiency of repair for different categories of devices influence consumers’ future purchase and recommendation decisions have been presented.

Most enterprises, technology and otherwise, are routinely collecting massive amounts of unstructured information from customer interactions and then attempting to extract knowledge from this information in order to improve core activities such as product development, customer support, and marketing. The knowledge engineering processes for extracting knowledge from this information are often largely manual and extremely inefficient in both cost and time. Therefore, software automation of these manual activities through the creation of highly user-centric Knowledge Engineering Software Products (KESPs) is critical to enabling the rapid and efficient extraction of high-quality knowledge. The primary intent of this paper is to provide a comprehensive theory, including its application and implementation, for developing high-value Knowledge Engineering Software Products. To this end, we have created a representation-based approach to the design and development of KESPs. The theoretical framework of our representational-based approach is the integrated metarepresentational model (IMRM) which provides a natural sequence of representations for guiding the development of complex artifacts such as KESPs. The application of the IMRM to the development of high-value KESPs resulted in the integrated representation-based process methodology (IRPM) which combines, in a rational and structured manner, methods and tools from the technical domains of Knowledge Engineering, Product Design, and Software Engineering. Each domain contributes a distinct set of methods to the IRPM. The knowledge engineering domain provides tools—such as the CommonKADS Agent/Task model—for modeling current work processes that the KESP will automate. The product design domain provides formal tools—such as the House of Quality, Function Structure, Morphological Matrix, and Utility Function—for explicitly defining the user needs for the KESP, and for exploring different design concepts in order to ensure the KESP is high-quality and low-cost. The software engineering domain provides tools—such as Unified Modeling Language (UML) Use Case, Component, and Class diagrams—in order to ensure that a reliable and easy to use KESP is delivered on time and within budget. We have demonstrated the feasibility of the IRPM by implementing it within the context of a real knowledge engineering problem involving the extraction of problem-solution pairs from customer service requests in order to create “smart” products and services. The developed KESP, called the “Service Request Portal” (SRP), used search and content filters to achieve a 30% productivity improvement over the previously manual work process.
