This paper proposed a part catalog system for personal manufacturing that emerges recently based on personal fabrication machines, social media and a set of accessible engineering software. To support deficiency of personal manufacturing, the lack of human resources, it aims to integrate design and customer support from the view of product life cycle management. Extending the previous study on integration of design and manufacturing to customer support, it provides a parts catalog system that consists of a parts catalog editor and a viewer. The editor itself is an extended product data management (PDM) system that manages product data for design and customer support in an unified user environment. The viewer allows easy access of customers or customer support agents to the parts catalog through Web environment. The editor and viewer also provide social media that can directly connect personal manufacturers and customers to support efficiency of customer support in personal manufacturing environment. The proposed system was implemented as a prototype parts catalog system based on an existing research and education purpose PDM system. This paper also applied industrial example data to the implemented system to verify the feasibility of the proposed parts catalog system.

This study attempted non-face-to-face collaborative product development practice that can respond to the spread of COVID-19 by expanding existing product data management system-based product development practice. For the complete non-face-to-face product development practice, it utilized prototype development using a 3D paper model, an online class management system and social media for classes and meetings. As a result of applying the non-face-to-face method, product developments of 26 practice teams have been completed without any failures. Therefore, through this study, the author can confirm that it is possible to provide the complete non-face-to-face collaborative product development practice based on product data management systems.
소셜미디어와 PDM 시스템을 활용한 협업적 제품자료관리 교육

This study proposes an approach to Product Data Management (PDM) education for collaborative product data management, which can support collaborative product development process. This approach introduces social media and a PDM system into a framework for PDM education supported by consistent product development process and product data model. It has been applied to two PDM classes and the result shows that the social media in PDM education can support not only experiences of the collaborative product data management but also interactive and informal communications among instructors and participants using integrated social media with product data during courses.

Acting an important risk management tool for main contractors, pre-qualification has served a key marketing tool for subcontractors in various industries. Current industrial environment has required the time intensive pre-qualification ability to small and medium-size subcontractors as a matter of competitive business. In order to support the subcontractors, this paper proposes a database model for pre-qualification management system (PQMS) that automates the pre-qualification process by using information technologies. The modeling process consists of specifications for its requirements, functional modules, and a database model for the PQMS.

As product development process becomes complex, it becomes more important for engineering students to experience collaborative product development. Especially the collaboration experience based on Product Data Management (PDM) systems is useful, since participants are likely to use the same environment for their professional product development. However, instructors have difficulties to evaluate contribution of each participant to their projects during the practices, since it is hard to trace personal activities for collaborative design processes. To solve this problem, this study suggests a data-driven objective method that analyses product data accumulated in PDM databases to evaluate numerically calculated contributions of participants to their class projects. As a result, the quantitative measures provided by the data-driven analysis with qualitative measures for project results can improve the fairness and quality of evaluation of contributions of participants to collaborative projects. This study implemented the proposed evaluation method with an information system and discussed the result of the application of the system to product development practices.
