In this paper, for integrating of data on car parts we model information of parts that PDM system manages. Ontology of car parts applies existing ontology mapping research to integrate into car ontology. We propose a method for semantic integration of PLM object of MEMPHIS based on the integrated ontology. Through our method, we introduce C# ontology model to apply existing C# applications with ontology. We also classify ontology integration into three through examples and explain them. While semantically integrating PLM objects based on the integrated ontology, we explain the need for change of PLM object type and describe the process of change for PLM object type by examples.

Tilting train has been developed to increase the operational speed of the trains on conventional lines which have many curves. This train are tilted at curves to compensate for unbalanced carbody centrifugal acceleration to a greater extent than compensation produced by the track cant, so that passengers do not feel centrifugal acceleration and thus trains can run at higher speed at curves. This paper developed PDM(product data management) to make a system engineering of TTX(tilting train express) with maximum operation speed 180 km/h.

요즘 우리는 인터넷이라는 디지털 혁명 속에 살고 있으며 그 영향력은 과거 산업혁명과 비교할 수 없을 정도로 산업 전반에 걸쳐 확산되고 있다. 조선 산업도 예외는 아니며, 각 조선소들도 인터넷 환경에 맞춰 생산 시스템을 구축하고 있다. 하지만 조선 산업은 그 업무의 특성상 생산을 계획, 관리, 통제하는 그룹과 생산 자체를 시행하는 그룹간의 양분이 뚜렷하여, 이를 통합한 전산 시스템을 구축하는데 어려움이 있다. 본 논문에서는 무선 인터넷 프로그래밍을 활용하여 XML 기반의 무선 PDM 시스템을 구현함으로써, 조선소 업무 특성상 구현하기 힘든 제작, 관리, 생산 부문을 통합하는 작업흐름 관리 시스템 구축의 가능성을 제시하였다.

PLM(Product Lifecycle Management) is one of innovative manufacturing paradigms which leverages e-business technologies to allow a company's product content to be developed and integrated with all company business process through the extended enterprise. In these days, most construction companies also make an effort to enhance their systems for creating, sharing and managing information to improve business efficiency through entire lifecycle of project execution. Because of different needs, business process and diverse engineering activities such as design, structural analysis, installing simulation, documents and data managements, a new paradigm for construction companies is needed to manage and share the entire workflow, and information in total project lifecycle. In this paper, we conducted user requirement and business process analysis of the construction to design architecture of C-PLM(Construction Project Lifecycle management) and implement a prototype of C-PLM systems based on commercial PDM system.

Concurrent engineering is considered in the 21st century product development and H&D. Moreover, advancements in IT and advanced system engineering technology enables to produce high-quality article and shorten the period of R&D. The paper propose work breakdown structure(WBS) based on the product data management(PDM), WEB based system engineering technique, to introduce and operate advanced system engineering technique. We will manage systematically all data produced in advanced urban transit system project based on the proposed WBS. Besides, we provide strategic information for improving efficiency of R&D in advanced urban transit system project. Futhermore, we manage data such as images, design drawings, documents as well as numerical data, and will establish PDM system for sharing the data.

This paper proposes a framework for product development including hardware and software components. The framework provides separation of the hardware dependent software, an integrated product development process, and integration of software components with product configurations and product structures. In order to separates the hardware dependent software, the framework considers product configuration modules and engineering changes of associated hardware and software components. The proposed product development process integrates development of the hardware dependent software into the existing product development process. In order to integrates the hardware dependent software with product configurations and product structures, the framework represents software components by existing product data models in Product Data Management (PDM). The framework is applied to development of a robot system including hardware and software components in order to show its effectiveness.

As the use of Internet being generalized, ordering system can be easily achieved on the Web so that the direct sailing system is replaced the various types of Built-To-Order system. It is important to give the up-to-date information to the end-user in order to build the Built-To-Order system. Recently, the way of providing information is updating the product related information continuously. In this study, we provide the method that can be streamlined Product Data Management System which manages a creation and update for product information into the direct BTO system in order to achieve the newest information. This methodology is not only transferring the information but also processing the information in an appropriate form. So this paper is going to cover the various point of view of information processing.

In order to care about preserving the environment for future generations, each country has been required to make the laws of the environment. So car manufacturers must design, manufacture and sell cars and trucks that meet customer's need and must do this while meeting the needs of the environment. In this research we have developed product structure and configuration management system that treats electronic catalogs for recycling of automobile parts. This research focused on two system. One is XML-based electronic catalog that give the information about recycling of automobile parts. The other is product structure and configuration management system based on electronic catalog.

In order to satisfy customers'various needs in the market, manufacturing companies tend to add similar variants to an existing product model. This variety causes immense growth of product configuration and makes data management uncontrollable. In order to resolve this problem, we propose a method to efficiently represent the variants in a single schema of product structure and configuration and manage the product configuration. First of all, the product structure which adopts the concept of features and options is suggested. Second, the method to represent option specifications which restricts option configurations is proposed. Finally, the prototype module, which inspects if a product configuration violates the option specifications, is introduced.

Presented in this paper is the development of an product cost estimation system at the product design stage. The efficient cost estimation function at the design stage is essential for the cost reduction activities through the entire product life cycle. For this purpose, it is necessary to establish a systematic working procedure, and to develop information system for managing a great deal of production and product-related data required for the cost estimation. The developed system has the capability of estimating a cost of assembly type products as well as unit-item type products. As proposed system is based on the variant approach, it can be used easily at an early design stage without the need for detail design information. Also, this system is integrated with legacy PDM (Product Data Management) and ERP (Enterprise Resource Planning) system for fast. accurate and easy product cost estimation. The estimated cost includes material cost, overhead cost as well as labor cost.
