This paper presents a structured framework for developing the embedded subsystem, called ESDMP (Embedded Subsystem Development Methodology for POP), which is one of core components at the development of POP (Point Of Production) system. It is essential that embedded subsystem development methodology must be closely related to the general information system development methodology from the early stage of system development. Therefore, this paper investigates the PDSM (Production System Development Methodology) that is developed by Korea Technology and Information Promotion Agency for SMEs and widely utilized at the fields of POP system development, and proposes the embedded subsystem development methodology aligned with each step of PSDM. The main characteristics of proposed methodology are as follows : First, it is developed to link each step of embedded subsystem development with relating steps of PSDM from the early stage of feasibility study. Second, it provides the procedure for designing and implementing hardware and software simultaneously. Third, it includes the method of reusability for developed products and modules.

생산시점 (Point Of Production)에서 생산정보의 발생원 즉, 기계, 설비, 작업자, 작업대상물 (Work) 등으로부터 생산 정보를 Paperless, 실시간(Real Time)으로 수집하는 장치를 POP 단말기라 하며, POP 단말기와 PC(관리용, 제어용)를 RS232, RS422, RS485 등의 네트워크로 구성하여 전생산라인의 정보를 실시간으로 얻을 수 있다. PC는 PC 상호간 또는 공장의 주컴퓨터(Host Computer)와 LAN(Local Area Network)으로 연결하여 공장 전체를 관리한다. 생산정보 및 라인 가동상태를 주컴퓨터에 연결된 단말기를 통하여 수시로 파악함으로써 생산계획의 수립은 물론 공장의 모든 인적, 물적자원의 효율적인 운용을 가능케 해주는 것이 바로 POP의 개념이다. 본고에서는 이러한 POP 개념의 실현을 위해 기계부품 생산라인을 대상으로 한 POP 단말기 시스팀 개발에 관하여 서술하고자 한다.

In this paper, we develop a real-time manufacturing control and information management(POP) system that can support realization of CIM and information network of manufacturing system. The POP system systematically collect informal data that is originated from working area and make an offer collected information to planning side. Especially, this study designs a modular POP terminal that directly extract and process momentary information from field source and provide it to control system on real-time. In addition, we apply developed POP system with open architecture to flexibly and optimally operate the manufacturing system based on CIM.

This paper describes a point of production(POP) system which collects and manages real-time shop floor machining information in a wafer dicing process. The system are composed of POP terminal, line controller and network. In the configuration of the system, LAN and RS485 network are used for connection with the upper management system and down stratum respectively. As a bridge between POP terminal and server, a line controller is used. The real-time information which is the base of production management are collected from information resources such as machine, product and worker. The collected information are used for the calculation of optimal cutting condition. The collection of the information includes cutting speed, spout of pure water, accumulated count of cut in process for blade and wafer defect. In order to manage machining information in wafer dicing process, production planning information is delivered to the shop floor, and production result information is collected from the shop floor, delivered to the server and used for managing production plan. From the result of the system application, production progress status, work and non-working hour analysis for each machine, and wafer defect analysis are available, and they are used for quality and productivity improvements in wafer dicing process. A case study is implemented to evaluate the performance of the system.

Rapid change of the era has caused change to consumption. New concept of consumer means not consumer who is simply provided a product, but a consumer who lays emphasis on value. That is to say, it indicates a consumer who values both on service and information as well as a product itself when they purchase. Therefore, the purpose of this research is to analyze the changes of POPs and objets at domestic and foreign fashion lingerie shops in different periods, and to encourage the effective introduction of POPs and objets for display at fashion lingerie shops in the future. I have used 100 pictures of 6 domestic brands and 80 of 6 foreign brands to analyze, and the periods were divided into 2000-2003, 2004-2007, and after 2008. The result of analyzing is as follows. First, give much information and great satisfaction to customers through the various types of POP, which convey the image and the concept of the products. If current POP was used only for sales, there ! should be various kinds and types of POPs to present not only basic information of products but also the value beyond it. Second, advance the products value by the presentation of diverse object. Furniture, fixtures, Lighting, Gift Box, Poster and mannequins should be used not to show simple props and presentation of product in the past, but to show brand images and Design concept of products.

This paper suggests a specific model that could efficiently improve the interaction and the interface between MES(Manufacturing Execution System) server and POP(Point Of Production) Terminal through RFID(Radio Frequency Identification) system in Automative Module Assembly Line. The proposed model shows that the new method by RFID can more efficiently perform to receive work order informations and transmit work performances, compared with the current approach by proximity sensor. As a result of the certain test among the MES server, RFID system, PLC(Programmable Logic controller) and POP terminal, it is noted in case of the automatic control by RFID that the effects of proposed model are as follows; (a) While the processing time per truck for carrying by the current method was 10 minutes, the processing time by the new method was 1 minutes. (b) While the error rate by the current method was 20 %, the error rate by the new method was 1 %.

In this paper, we propose an architecture of the DNC system for Shop Floor Control/Point of Production(SFC/POP). The DNC system to be presented this paper retrieves line-up sheets which include the drawing information, making a index database for line-up sheets, NC programs and tool adjustment data. And it is interface with a raw material, jig and tool information. Also, the DNC system transmits operation information to real workers rapidly, and supports realtime monitoring by collecting the state information of machines directly. In the analysis and design phases, this paper models realtime events using the state transition diagrams. In the implementation phase, we use the ORACLE DBMS(Database Management System) as the DBMS and Developer 2000 and Microsoft Visual C++ 5.0 as the programming tools.
