This study was designed for automated pattern drawing and grading a man's Durumagi, Korean traditional coat in order to reestablished and grade the pattern by Apparel CAD SYSTEM. For the study, AM-250 systems of Gerber as the computer and Macro program as the automated drawing were used. Also, PDS(Pattern Design System) was used for the grading of the original Durumagi pattern. Results were followings; First, the size data that could be standardized by reestablishing the pattern of a man's Durumagi by each size was presented. Second, The pattern was developed by each size. Third, new design was propose for mass production with the traditional design of the DURUMAGI Fourth, The time for making DURUMAGI pattern and the cost through the automated drawings by using the Macro program were reduced. Moreover, was presented the basic data for a ready to made garment like the Western garment. Five, A man's DURUMAGI by CAD System was graded that could be applied to ready to made Hanbok

The purpose of this paper is to establish an automated die design system for compacting and sizing process required in Powder Metallurgy. Though the Powder Metallurgy(P/M) is a practical and economical forming technology, it needs long time and many trials and errors for die design. Such a problem can be solved by introduction of the automated die design system for P/M. In order to establish the system, collecting, classifying, and systematizing related knowledges from the experts in industries, books, and papers were performed. The system was constructed by AutoLISP, the language operated in AutoCAD atmosphere. This language can efficiently support for user to work on drawings. There are three modules ; P/M part specification input module, P/M part design module, and Die design module. A part for vehicle was applied to the system and satisfied results were achieved.

The present automated manufacturing environment is very different when the classical statistical process control method based on batch processing were used. Therefore these must be replaced by automated statistical process control method. In this point of view, this paper intends to develop the automated statistical process control method which can be implemented in the present automated manufacturing environment. Specially this study developed the rules to identify the special causes of the manufacturing process in the aspect of the 100 PPM management, and a numerical example is demonstrated to verify the usefulness of these rules.

Recently, to improve operating efficiency with the higher in-line rate in automated production lines, a lot of cases of grouping machines and material handling system together to form a cluster has shown frequently. This article addresses the job allocation and operation method of automated material handling for cluster-type production systems. First of all, the control problems of the automated material handling systems are classified into the control problem of inter-cluster material handling system and that of intra-cluster material handling system. Then, a distributed agent-based control scheme is proposed for the former, and an operational control procedure for the latter. Simulation experiment shows that the proposed method is efficient in reducing cycle times and improving utilization of material handling vehicles.

This paper suggests a new object-oriented methodology, ESBD(Evolutionary Simulation Based Design), for the development of an automated manufacturing system in shipbuilding. The target system, AHMS(Automated Hull-piece Manufacturing System), is a virtualized and distributed system controlling the manufacturing processes of storing, surface-pretreatment, cutting, 1st and 2nd curvature generation of material plates. The control and product-flow simulation is applied for the real-time product monitoring and product data management(PDM). The prototype system of AHMS also outlines the layout of the new automated factory.

The rapid expansion of the Internet-related technology has changed the current commercial transaction process. In the physical commercial transaction, most deals are accomplished through the negotiation process except a fixed price system. Thus, the negotiation is essential to conclude the business transactions. Especially, under the e-commerce environment, an automated negotiation system is necessary to respond quickly and flexibly to the diverse environmental changes and also to perform negotiations consistently and effectively. To this end, we develop an automated negotiation system using multi-agent technology. This new system includes such functions as creating negotiation proposals automatically, evaluating the counterpart’ proposals, and preparing counter offers.

As a result of the recent development of the electro-information industry, the hardware of an automated ultrasonic testing system is getting lighter and diversified image processing techniques are applied to its software so that the possible precise totaling and detecting of the flaws are studied. This study proposes an automated ultrasonic testing system of the pipe in order to organize the optimized system, and also describes the data flow and general composition of the software for the design of the system.

Simulation has been recognized as one of major application areas of world wide web. Over the last several years, most research has been focused on the development of web-based simulation languages mostly using JAVA and validation of simulation modeling on web with the newly developed languages. In this paper, we develop a tentative web-based simulator for a simple unit-load automated warehouse system, named Web-SAW. In constructing Web-SAW, we program a user interface program, a simulation logic program, and an animation program with JAVA while utilizing the class library functions and embodiment environment of existing web-based simulation languages. Web-SAW simulates the automated warehouse system with the user input about system operation, displays the animation on a static background representing the system, and generates the various textual outputs after simulation.

The purpose of this study was to suggest the data of base for automated underwear manufacture by analyzing the technology of the automated underwear manufacturing facilities in the area of Jeonbuk with a focus on Jeonju and Iksan. The case study samples were 6 underwear firms. The results were as follows : 1. Automated underwear manufacturing systems in the area of JeonBuk introduced over the entire period between 1990 and 1997. Most of Their production type was multi-kind and small-quantity production. 2. They were using Gerber, Assyst, Lectra, Microdynamics and Investronica systems as the CAD/CAM system, of which the Gerber system was mostly used by them. 3. In the stage of production planning and in the stage of preparation for production, most of them realized automation, but in the stage of main production, every firm did not realize automation. In most cases, they used both the stage of mechanization and the stage of unit process automation.

There has been growing interests in life-cycle project management in the construction industry. A lot of attention is given to Building Information Modeling (BIM) which stores and uses a variety of construction information for the life cycle of project management. However, due to the additional workload arising from BIM, its expected effects versus its input costs are still under discussion in practice. As an attempt to address this issue, one of previous studies suggested an automated linking process by developing Standard Classification Numbering System (SCNS) and Geometry Breakdown Structure (GBS) to enhance the efficiency of integration process of BIM objects, cost, and schedule. Though SCNS and GBS facilitates identifying all different dataset, making object sets and linking schedule activities still needs to be manually done without having an automated tool. In this context, the purpose of this paper is to develop and validate a fully automated integration system for 3D-objects, cost, and schedule. A prototype system for single family homes (Hanok) was developed and tested in order to verify its efficiency.
