  • Most commercial PDM (product data management) systems, which have been released recently by overseas famous software vendors, are still expensive and heavy to apply to small and medium enterprises (SMEs). Proposed in this paper are an architecture and functions of collaborative BOM (bill-of-material) management system (cBOM-MS) which supports the internal BOM management by BOM Navigator, provides SMEs with constructing the collaborative BOM via Collaborative BOM Portal, and proposes an interface to extract BOM automatically from commercial CAD systems. In the design of cBOM-MS, BOM Navigator and cBOM Portal are positioned separately to reinforce the information security about product data during product development process.

  • Documents in a traditional PDM(Product Data Management) system have been managed in a form of scanned document files or electronic documents developed by specific tools. Though each tool manages documents with its own systematical methods, it has drawbacks in data search, data integration and interchange, etc. For this reason, in this research we propose an efficient document management system for PDM by using the SGML(Standard Generalized Markup Language), one of CALS and ISO standards for document interchanges. Among documents to be managed in PDM, the engineering change notification (ECN) is taken into account. The DTD (Document Type Definition) has been constucted based on the logical analysis of the documents format, In addition, based on the DTD, DB classes have been designed by object-oriented paradigms and a prototype for document input/output and search has been developed using UniSQL ORDBMS (Object-Relational DBMS) and PowerBuilder under the client/server environment.

  • 본 연구에서는 STEP 표준을 고려하지 않고 설계·개발된 기존의 PDM 시스템이 CAD 시스템에서 생성된 STEP 포맷의 제품 데이터를 활용할 수 있도록 하기 위한 데이터 변환 방법을 제시하고자 한다. 이를 위하여 AP203 응용 프로토콜의 분석과 함께 스키마 매핑을 위한 방법과 절차를 제시하였다 그리고, 이를 바탕으로 AP203 스키마와 ‘중소기업형 PDM 시스템'의 DB 스키마간에 매핑을 설계하였다. 또한, CAD 시스템에서 생성된 제품의 Assembly 구조를 PDM 시스템의 BOM 구조로 변환하기 위한 알고리즘을 함께 제시하였으며, 제품의 product structure를 중심으로 데이터 변환을 위한 STEP-to-DB 변환기 프로토타입을 개발하였다. 그리고, CAD 시스템에서 생성된 제품 데이터에 대한 STEP 스키마 구조와 AP203 응용 프로토콜 스키마와의 구조적 차이를 비교·분석함으로서 CAD 시스템에서 생성된 STEP 포맷의 제품 데이터 구조에 대해 엔지니어링 데이터로서의 구조를 갖도록 하기 위한 기초 자료를 제공하였다.

  • A web-based Computer-Aided Engineering (CAE) supporting system is connected with a Product Data Management (PDM) system for Small and Medium Enterprises (SMEs) suffering from the lack of building hardware, software and related experts. An analysis of current business models and worksite requirements provides an improved process model and data to be shared between the PDM system and the CAE supporting system. Since all engineering tasks such as geometric modeling, mesh generation, static stress and modal analysis, and fatigue durability analysis are automated in the CAE supporting system, the user in charge of the CAE have only to configure the concerned values of design variables and result data through the web page. The existing Change Management module of the PDM system is modified for seamless data exchange, i.e. sending the Engineering Change Order (ECO) data to the CAE supporting system and receiving the CAE result data bark. The hi-directional data transfers between the PDM system and the CAE supporting system is made possible by adaptors bused on the Simple Object Access Protocol (SOAP). The current approach will be very helpful for SMEs that only have the PDM system and have no adequate infrastructure for CAE.

  • 기존의 제품 수명주기 관리 프로그램은 공급망 관리(SCM :Supply Chain Management)의 목적이 강해 그의 기능이 풍부한 반면 PLM적인 요소가 부족하다. 따라서 본 논문에서는 PLM을 구성하는 PDM, CPD, CNM, PPM 4가지 요소 중에 하나인 PDM(Product Data Management) 요소를 보강하기 위한 모듈을 개발하여 구현한다. PDM의 기능은 핵심적인 고객가치를 지원하기 위한 제품정보를 관리하는 영역으로 제품구조관리(BOM), 기술문서 관리, 설계변경 관리, 제품 기준정보 관리, Software 형상관리, 환경 유해 물질 관리, 공용화 기능을 포함하고 있는데, 그 중 제품구조관리(BOM)가 가장 중요한 부분이므로 이 부분에 대해 구현한다.

  • It was difficult that each enterprise clearly defines PDM in domestic vehicle manufacturing industry and decides investment for the successful foundation in the mid-90s. Also, it was true that most investments to success repeat a process of trial and error even if they decide and propel. Now, PDM is not a luxurious system. Because the company is operated well even if it manages business manually, the company may not be interested in PDM introduction. Problem is business efficiency and product competitiveness. Now, we must consider that introduction and drive of PDM became necessary as instrumentation for Re-Engineering of business process concerning innovative dimension restructuring that is not reorganization, development and improvement of business for enterprise's survival. This indicates that now is when level of infra construction for an IT technology dominates competitiveness of business management. Enterprise can expect effects of PDM by implementation that manages Intellectual Properties through administration of knowledge and information finally.

  • The current challenge with which most shipyards are faced is to reduce the design time and the time-to-delivery benefits of new information technologies such as ERP, APS, and SCM system. These technologies should integrate the information that flows in the enterprise wide activities. First of all we should maintain control of ship design and product data such as bill of material, product structure, drawing, 30 modeling and manufacturing information for the integration. The product data management (POM) system copes with these requirements. All the product data is stored in POM database and vaults in a structured manner and all the changes of product data are monitored, controlled and recorded. This study discusses how POM system can be implemented in shipyard. The procedure is surveyed to apply a POM system for the ship design data management. This study also presents several examples in order to make a practical guidance for ship POM implementation. Proposed studies can be useful for shipyards planning to adopt POM systems in enterprise wide manner.

  • The challenge is to maximize the time-to-market benefits of concurrent engineering while maintaining control of data and distributing it automatically to the people who need it when they need it. The way PDM systems cope with this challenge is that master data is held only once in a secure vault where its integrity can be assured and all changes to it monitored, controlled and recorded. The structure of PDM is various from vendor, but they have common module. That is PDM and it is most important. The goal is to design the workflow in PDM using object-oriented modeling method. The past methods have concentrated on the flow between workflow engine and agent, but this paper will focus on task. We will model task as individual object. This paper uses OMT(Object Modeling Technique) by James Rumbaugh for base modeling tool and uses DCOM(Distributed Component Object Model) for base ORB(Object Request Broker). Research object is to design the static object model, to design state change by dynamic model and to design data transition by functional model.

  • Object Management Group(OMG)는 1989년부터 객체 지향 개념에 기초하여 상호 호환구조의 규격을 개발하여 왔으며, Manufacturing Domain Task Force(MDTF)는 1996년 8월에 PDM Enablers를 위한 RFP를 발표하였다. 이 RFP는 PDM 시스템들에 의해 제공되는 기능들의 표준 인터페이스를 구축하기 위한 것이며, 이러한 표준 인터페이는 분산된 이기종 PDM 시스템들이 상호 호환할 수 있는 기초를 제공할 것이다. 본 고에서는 OMG RFP의 내용을 간단히 요약하고, 이에 대해 Dassault 시스템과 NIIIP Consortium이 공동으로 제출한 제안서를 소개한다.
