In this paper, development of TIM Module for constructing PDM will be introduced. Technical information relevant product data influences cost, quality, precision and productivity. One of the very important feature of product data is organizing not by oneself but very closed to many technical information such as document, file, image and analysis sheet. To manage various technical information, several kinds of management system are used in multi level of production system. PDM and TIM systems are being developed for suitable purpose and are in need of Network technology, Information Technology, Database, sharing and distributing information. Developed TIM system is based on Web environment. By using this system, we can manage systematic technical information and reduce cost for constructing PDM system. And also we will put to practical use another technical information management system for mold plant.

It is certain that the future manufacturing environment will be network-centric and spatially distributed based on Internet. Today, wide variety of distributed computing and communication technologies are available for implementing a system for product data exchange and sharing. One of the technologies that have been received most attentions for product data exchange and sharing is Product Data Management (PDM). PDM tries to integrate and manage process of data and technical documents that are connected to physical product components. In accordance to previous researches about PDM, it can be regarded as an integration tool of many different areas, which ensures that the right information is available to the right person at the right time and in the right form throughout the enterprise. PDM with Web-enabled CAD system is proposed in this paper in order to acknowledge the usefulness of the system mentioned. The system will use Web service on Visual Studio C#.Net to invoke the web application system.

For the success to PLM in manufacturing industries, the creation, management and coordination of all product-related information are essential, and the exchange of product information and data has become an important part of the product development. In this paper, we define the neutral schema, and it refers to PLM Services. Based on this neutral schema, we develop the PLM Integrator to exchange product information and data between diverse heterogeneous systems including PDM systems. We apply the PLM Integrator developed in this paper to commercial PDM systems such as SmarTeam, Teamcenter Engineering and MEMPHIS which is a data exchange middleware system for VR applications. By implementations, exchanges of product information and data can be done without loss of information. Also, the PLM Integrator can upload and download product information, data and related files. The result of this paper can not only reduce unnecessary efforts for data exchanging between different information systems including PDM/PLM systems but also provide a collaborative environment for PLM.

본 연구는 선박 추진시스템 설계를 위한 제품정보관리(Product Data Management, PDM) 시스템의 구현 사례를 소개하였다. 객체 지향 모델링 언어(Unified Modeling Language, UML)를 이용하여 중소형 선박 추진성능 추정 시스템을 설계하였으며, 프로펠러의 3차원 디지털 모크업(Digital Mock-Up, DMU)을 중심으로 제품정보를 구축하였다. 또한 설계 과정에 필요한 모델링 및 시뮬레이션(Modeling & Simulation, M&S) 기술을 PDM 시스템과 통합하기 위한 방안을 제안하고, 추진기 및 축계 설계 검증 모델을 동시에 구현하였다. 시스템 개발에는 Open Scene Graph(OSG) 라이브러리 및 객체 지향 시스템 개발 도구를 사용하였다. 최종적으로는, 설계 검증용 M&S 소프트웨어와 PDM 시스템을 연동한 구현 사례를 보임으로써 추진성능 추진 시스템의 개발환경 구축 방안을 제시하였다.

The product-level carbon footprint (PCF) is a comprehensive and widely accepted metric for sustainable product development. However, since a full PCF study in general is time and cost intensive, it is not feasible for the product development team to synchronize the activity to the main product development process. In addition, the current dedicated life cycle assessment (LCA) tools for calculating PCF, separated from the main product data management systems, have limitations to provide timely PCF information for design decision makings and collaborations between design and environment engineers. This paper examines the possibility of the extension of the current product data model that can support the PCF calculation with PDM (Product Data Management) databases. The product data model can represent not only the content of products but also context or system information of the products. The product data model can be implemented as a PDM database that can satisfy the needs for handy and timely PCF calculations from the consistent product data for dynamic design decision makings and engineering collaborations.

This paper proposed a Web-based training service for product data management by supporting an integrated product data management system, various technical documents. and efficient communication systems. It also supports a general product development process and a consistent product data model that enable participants to experience management of consistent product information during the product development life cycle. The Web based environment of the service also provides participants with a collaborative workplace with other participants and a Web portal for all the components of the service.

The low price around 1000 USD makes consumer 3D printers as a new additive manufacturing platform for the personal manufacturing where consumers can make and sell their own products. To allow the consumers to design and manufacture their products, not only economic 3D printers but also supporting information systems for their design and manufacturing are essential. This study suggests an extended product data management (PDM) system that can support both the design and manufacturing of personal products with consumer 3D printing services. This extended PDM system helps consumer designers use advanced PDM technologies for their design and connected 3D printing services with Internet of Things (IoT) technology for realization of their products. As a result, the proposed system supports the consumer designers a seamless integrated product development and manufacturing environment supported by PDM and consumer 3D printing services.

In order to adapt today's short product life cycle and rapid technology changes., integrated systems should be extended to support PDM (Product Data Management) or CE(Concurrent Engineering). A PDM/CE environment has been developed and a prototype is Presented in this paper. Features of the PDM/CE environment are 1) integrated product information model (IPIM) includes both data model and integrity constraints, 2) database systems are organized hierarchically so that working data C8Mot be referenced by other application systems until they are released into the global database, and 3) integrity constraints written in EXPRESS are validated both in the local databases and the global database. By keeping the integrity of the product data, undesirable propagation of illegal data to other application system can be prevented. For efficient validation, the constraints are distributed into the local and the global schemata. Separate triggering mechanisms are devised using the dependency of constraints to three different data operations, i.e., insertion, deletion, and update.
