A Study on IETM Conversion procedure and IETMDB Construction
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 1~25
This study aims to provide conversion process to acquire IETM and fundamental IETMDB construction necessary for IETM. As the weapon system and other equipments are highly advanced and electronically sophisticated, the amount of information necessary to operate and maintain the systems is being dramatically increased. Thus, it is theoretically and practically impossible to maintain the huge amount of information in the paper-based manual. Furthermore, the vast amount of paper based-technical information makes it difficult to share them in real time. This paper discuss how to solve these prolems by using highly advanced information technology such as network, database, data communication, etc First, we propose an effective conversion process for the decision of IETM classes from Class 1 to Class 5. Second, we also propose a construction of IETMDB and IETM system by using CALS standard and Content Data Model (CDM).
Building CALS System using CIM in Manufacturing Company
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 27~47
Manufacturing companies must have close relationships with cooperative companies and customers under dynamic market surroundings. Not only product life cycle, but also the allowed period between development of product and sale becomes shorter. In spite of these situations, most manufacturing companies have insufficient capabilities of the information technology and data exchange formats between companies are so different. Thus, there exists a limit on the efficient management of companies. These problems in manufacturing companies could be solved by CALS. Through CALS the company responses quickly to customer demand, transfers this information to manufacturing systems automatically, and distributes products at appropriate time In short, CALS is a strategy to distribute products satisfying with quality, cost and delivery. And up to now, most manufacturing companies have proceeded CIM systems. In this paper, an approach for the efficient building CALS system through extension of CIM in the manufacturing companies is proposed.
A Study on Conceptual Design through Function-to-Process Flow Model Transformation
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 49~76
An industrial process is a sequence of steps intended to perform a useful task in an industrial organization, and can be described using a model or a representation framework such as function model, information model, process flow model, etc. Many researchers, however, claim that, all those models from different perspectives are required to describe complex systems such as CIMS. Thus these perspectives should be put together to build an optimal system. And the need for interconnection or transformation among different view points has arisen for effective communications between system developers and easy propogation of local changes in a model. But it seems to be difficult to integrate such models into a unified framework as they describe different aspects of the system on different purposes. This study is an attempt to interconnect these different perspectives, and thereby to support conceptual design of systems in a more effective manner. A methodology to transform the IDEFO functional model into a process flow model is proposed. The validity of the proposed approach is tested by developing a prototye of a computer-assisted design system on the operation processes of FMS installed at Seoul National University - Automation and Systems Research Institute.
The Object-Oriented Modeling for Drawing Information Management Systems
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 77~92
In recent years, the manufacturing industry begins to demand the PDM which integarates design and manufacturing information concurrently to reduce the time-to-market of new products. However, current commercialized PDM tools have drawbacks in representing by relational data modeling a variety of data types such as CAD files, images, audio, long text, etc. For this reason, object-oriented approaches are suggested as an alternative. In this paper, using one of object-oriented approaches, Rumbaugh's OMT(Object-Modeling Technique), we propose a data model of drawing information management systems essential for PDM. The scope of the model is limited to the information management for drawings, parts, and product structures. Static, dynamic and functional models are suggested in detail. In the models, the drawing status is classified into on-progress, approved, disposed, and released. Also, parts are classified into products, assemblies, and components.
Product Data Model ing for Engineer ing Database
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 93~116
Nowadays, there are many efforts to integrate CAD/CAM and other systems. The key of integration is engineering database implementation through the product data definition. In this paper, we suggest the product data definition and their properties for electronic consumer product throughout the requirement analysis for engineering database. Electronic consumer products include electric/electronic parts. as well as mechanical part which mainly compose of machinery. The paper is composed of three parts: the first is analysis about engineering data base. the second is understanding of product data structure and properties. and the last is modeling of product data including static and dynamic characteristics.
IDEF0 Models of the FCIM System for CALS Implementation
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 117~131
This paper presents the results of the systems analysis for the FCIM (Flexible Computer Integrated Manufacturing) system at the U.S. Tobyhanna Army Repair Depot, which is one of the RAMP (Rapid Acquisition of Manufactured Part) program sites for CALS implementation in the U.S. military. The FCIM system's acquisition and supply processes are represented by IDEFO function models and FCIM information systems are briefly decribed in this paper. The models presented here can be used at a reference for the development of CALS acquisition and supply systems. In addition. the distinction between input and control information on the IDEFO model it suggested from the practical modeling viewpoint.
A Study on the Practical Usage of STEP data
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 133~160
It is accomplished on the practical usage for STEP in enterprise. But they has feeble grasp of STEP, therfore it is hard to apply. That is due to take a negative policy with the lack of advertising and understanding, most of studies are going on a studentlike attitude rather than the practical usage or implementation, so they don't know exactly what is STEP, and how can they apply to their own enterprise. This paper aimed to present more detail understanding of STEP usage and practical usage of STEP data in enterprise. We describe EXPRESS that is description method of STEP, four ways of implementation method, and introduce to using ST-Developer and ST-Oracle by STEP Tools Inc. for more detail understand of STEP. Thereafter we propose practical usage of STEP with CAD systems and PDM systems on the knowledge of previous study, and propose total system implementation image on STEP data in enterprise, finally discuss conclusion and luther study issues.
Mediating Conflicts in Concurrent Engineering / Design Environment
Kim, Myong-Ok ;
The Journal of Society for e-Business Studies, volume 1, issue 2, 1996, Pages 161~173
It Is a typical scenario in concurrent engineering/design that different perspectives of each team members participating In the project exist, and those perspectives lead to conflicting decisions. The model 'resolution network' proposed in this work provides system-mediated resolution for all related team engineers to consider to optimize the manufacture in general. This paper focuses on development of the general architecture of the model and a search engine called Mediator to determine a resolution network from a given constraint network. The Mediator manages the constraint network, determines the most optimistic resolution called optimal point in terms of satisfying overall production goal , and use the optimal point to mediate controversial issues among teams. The biggest merit of our model is that it provides teams with resolution with logical and rational reasoning.
