Time to market and cost-efficient production are some of the challenge that manufacturing industries face. Modern methods of engineering can't help such organizations attain competitive advantage. To help these situations, MEMPHIS (Middleware for Exchanging Machinery and Product Data in Highly Immersive Systems) was introduced as an approach that enables VE (Virtual Engineering) and links engineering applications with VR (Virtual Reality) solutions. Thus an environment is provided to implement virtual design reviews and enable the application of virtual prototyping methods. However MEMPHIS could just handle Product data for virtual design review and simulation. In this paper, we newly define and develop the extended MEMPHIS that enables virtual manufacturing with Process, Resource and Plant data as well as Product data.

본 논문에서는 ICT(Information Communication Technology) 기술을 이용하여 스마트팩토리 기반 CPPS(Cyber Pysical Production System)를 활용한 Digital-Twin 플랫폼 개발과 관련된 연구를 제안한다. 본 연구를 통해 개발된 플랫폼은 선행 제조 공정 계획 단계부터 BOP(Bill of Process) 관리 기능을 포함하여 P3R(Product, Process, Plant, Resource)을 연계한 3D Model 시뮬레이션 기능을 수행한다. 또한 생산 공정, 설비, 레이아웃, 생산량 예측이 가능한 Digital Twin 플랫폼을 제안한다. 본 논문을 통해 제안된 플랫폼은 초기 계획 설계 단계에서부터 제조, 생산, 운영 및 유지보수 단계까지의 전체 스마트팩토리 제조 공정을 관리할 수 있는 특징을 제안하였다.

Generally, a PLM education program in university consists of lectures of theory, software lab and software development raining as an advanced subject. Most industries want more than these, such as practical problem solving capabilities, teamwork skills and engineering communications including human relationship, rhetoric, technical writing, presentation and etc. Problem-Based Learning is a problem-stimulated and student-centered teaming method, and an innovative education strategy for collaborative and self-directed learning by applying real world problems. Education paradigm changes from "teaching" to "learning" accomplished by team working, and students are encouraged to develop, present, explain and defense their ideas, suggestions or solutions of a problem, and the "cooperative teaming" proceeds spontaneously during team operations. Co-operative education program is an into-grated academic model and a structured educational program combining classroom learning with productive work experience in a field related to a student's academic or career goals. Based on the partnership between academic institutions and industries, students are engaged in real and productive "work" in the industry, in contrast with merely observing. In this paper, PBL with Co-op program is suggested as an effective approach for PLM education, and we made and operated a PBL-based education course with industry co-op program. The Co-op education in industry accompanied with the PBL course in university can improve practical problem solving capabilities of students, including modeling and management of P3R(Product, Process, resource and Plant) using commercial PLM software tools. By the result, we found this to be an effective strategy for helping students, professors and industries succeed in engineering education, especially PLM area.
