To cope with the challenge of competitive market, manufacturing system needs to be agile in terms of its reconfigurability and scalability. For a system to be adapted to changed requirements, decision support tools such as configurator have to be provided. This paper introduces the basic framework of a configurator for assembly system Based on the factory data model(FDM) depicting the overall structure of a manufacturing system, functions of the configurator are described, i.e., requirements analysis, module selection and configuration optimization.

The platform for displaying cars has been changing with the times. From the popularity of paper media to the rise of computer graphics, the improvement of technology has brought more space and possibilities to the automotive industry. Yiming Zhong proposed the workflow of car configurator through Unreal Engine 4 to implement the basic functions of configuration in 2021, according to Yiming Zhong's final presentation, there is still room to improve the realism of graphics and functionality of the car configurator. Therefore, in this paper we propose to upgrade the car shaders and lighting environments according to the real-world physics and add multi-scenes switching function to car configurator. However the multi-scenes switching function also brings a large amount of data, which leads to the problem of display lag. At the end of the paper, we use the level of details(LOD) process to reduce the amount of data for real-time computing in Unreal Engine 4 and the increase of frames per second(FPS) values verifies the feasibility of our optimization solution.

In this paper, a method for the efficient implementation of the PICNET network configurator for a distributed control system(DCS) is proposed. The network configurator is composed of the time parameter estimator and the period scheduler, the file generator. The main role of network configurator estimates time parameter, the pre-run time scheduling of the user input and make the period transmission table for operating the PICNET based distributed control system.

Recent developments in component technology enable the construction of complex software systems by assembling together off-the-shelf components However, It is still difficult to develop efficient, reliable, and dynamically configurable component-based systems. Unspecified dependencies and behavior on components often has cause the source of the trouble. Therefore, component-based software systems must maintain explicit presentations of inter-component dependence and component requirements. In this paper, I describe the design on repository of component service to deployment, status reporting, and control in component service. Through the existing researches to customize component technology, I present the algorithm that supports dynamic dependency interface in order to reuse context of application.

본 논문에서는 개방형 운영체제인 리눅스상에서 package streaming service를 제공하는 Network Streaming Service(통칭 NSS)를 설계하는 문제를 다룬다. NSS는 client가 serve 측에 설치된 소프트웨어 package를 마치 client 자신의 local disk상에 이미 인스톨된 패키지를 실행하는 것처럼 동작하도록 해준다. NSS는 client측의 NSS Mounter, Package Streaming Consumer, NSS Configurator와 server측의 NSS Load Balancer, Package Streaming Supplier, NSS Manager, Accounting & Security Manager로 구성되며 local disk caching과 background prefetching 기능을 사용하여 향상된 서비스를 제공한다.

IEC 61850은 변전소자동화시스템에 대한 국제 표준 규격이다. IEC 61850 파트 6은 통신관련 IED(Intelligent Electronic Device) 구성과 IED 파라미터, 통신 시스템 구성, 개폐소 구조 및 이들 간의 관계를 설명하는 파일 형식을 규정한다. 이 파일 형식의 주요 목적은 IED 능력 설명, 호환되는 방법으로 여러 제조사들의 IED 엔지니어링 도구와 시스템 엔지니어링 도구 간의 SA 시스템 설명을 교환하는 것이다. 본 논문에서는 XML을 이용한 IED Configurator TOOl 구현을 제시하였다.

Besides strong customer orientation, today's companies should respond increasingly to a market getting worse for securing competitiveness with a diversity of product spectrum. In these new conditions in the surrounding field of manufacturing, the changeability of manufacturing system develops more and more to the key success factor. The following contributions introduce a fast and cost-efficient concept for changeover which bases on a modular system's architecture. The modular structure of manufacturing system allows the required changing processes with limited side effects on other modules. Based on a modular concept, manufacturing systems can be easily configured and reconfigured to specific requirements.

Configuration은 도메인 지식을 이용해서 주어진 모든 요구를 충족시키는 컴포넌트를 갖는 시스템을 구성하기 위한 기술이다. 최근 전자 상거래는 역경매, 공동구매, 사용자 프로파일에 의한 제품의 추천 등 다양한 방식으로 구매자 중심의 사거래 행위를 하고 있다. 하지만 아직도 전문 지식이 필요한 제품의 구입시에 구매자는 많은 어려움을 겪고 있다. 이러한 구매자의 행위를 보조하기 위한 수단으로써 전문가 시스템에서 수년간 연구되어 온 Configuration 기술을 확장 도입하였다. 본 논문에서는 도메인에 대한 규칙(Rules)에 기반해서 Classification Problem Solving 방법과 Constructive Problem Solving 방법을 적용하였다. 구매자와의 능동적인 질의 수행을 하여 제품에 대한 요구를 정확히 한 뒤, 얻어진 사실(Facts)을 Classification Problem solving에 이용이 되어 제품 모델이 결정된다. 이 제품 모델은 구매자를 위해 특성화 되어 있기 않기 때문에, Constructive Problem Solving을 이용한다. 이런 내용을 기반으로 컴퓨터 조립을 위한 Configurator를 디자인하고 구현했다.

The digital electronic switching system has some problems, when this system processes OAM(Operation, Administration And Maintenance) messages about the fault, the traffic, the account, and the performance, etc., at the present. One of these problems is that each the module processing these messages in the digital electronic switching system can not process OAM messages out of another digital electronic switching system. Each the module processing these OAM messages, that is, has been programmed in order to process only the OAM message out of the digital electronic switching system mounting itself, not to process the message out of the digital electronic switching system based on another platform. Therefore, we studied on methods that could process OAM messages out of all digital electronic switching systems and, first of all, developed the MGS(Message Gathering System) to be able to accept and process the fault message of OAM messages out of all digital electronic switching systems in real time.
