In the era of the 4th industrial revolution driven by the convergence of ICT(information and communication technology) and manufacturing, research on smart factories is being actively conducted. In particular, the manufacturing industry prefers smart factories that autonomously connect and analyze data. For the efficient implementation of smart factories, it is essential to have an integrated production system that vertically integrates separately operated production equipment and heterogeneous S/W systems such as ERP, MES. In addition, it is necessary to double-verify production data by using automatic data collection technology so that the production process can be traced transparently. In this study, we want to show a case of data-centered integration of a large aircraft parts processing factory that requires high precision, takes a long time, and has the characteristics of processing large raw materials. For this, the components of the data-oriented integrated production system were identified and the connection structure between them was explained. And we would like to share the experience gained through the design and implementation case. The integrated production system proposed in this study integrates internal components based on data, which is expected to serve as a basis for SMEs to develop into an advanced stage, and traces materials with RFID technology.

비순환식 고형배지경에서 배액이 토양과 지하수 오염을 발생시키는 문제를 해결하고자 그동안 연구된 데이터를 바탕으로 배액 최소화 재배방식을 확립을 위해 본 연구는 토마토 코이어 수경재배농가 시설에서 FDR 센서, 적산일사량 센서 및 타이머를 이용하여 토마토를 재배하며 급배액량, 생육 및 생산량을 비교하였다. 정식 후 88일까지 일일 식물체당 평균 급액량은 처리구에 따른 큰 차이가 없었다. 하지만 정식 후 88일 이후 107일 까지 TIMER, FDR, IR 제어구 각각의 일일 식물체당 평균 급액량은 IR(2125mL) > TIMER(2063mL) > FDR(1983mL) 수준이었고 108일부터 120일 까지는 IR(2000mL) > TIMER(1664mL) > FDR(1500mL) 수준 이었다. 배액률은 TIMER 제어구의 경우 5~12%, FDR 센서 제어구의 경우 0~7%, IR 제어구의 경우 12~19% 수준으로 IR > TIMER > FDR 순이었다. 정식 후 88일 이후부터는 FDR과 IR 제어구가 급액량에 상이한 결과를 보였는데, 이는 재배 후기 즉, 5월 20일 이후 (정식 후 94일) 누적일사량의 증가로, IR 제어구에서는 급액이 증가된 반면 FDR 센서 처리구는 적심 이후 30일이 경과된 6월 2일경부터 IR 제어구 보다 일일 급액량이 평균 500mL 적게 공급된 결과이다. 식물체 생육 및 상품과 수량도 급액방식에 따른 통계적 유의차는 없었지만, 당도는 FDR 처리구에서 TIMER 처리구에 비해 약 11%, IR 처리구에 비해 약 18% 높았다.

The automobile manufacture is a typical integrated assembly production that the numerous parts are committed sequentially to the assembly line. In this type of automobile manufacture, WBS (white body storage) and PBS (paint body storage) are operated to adjust the production sequence and to buffer. Starvation (impossibility of production owing to the insufficient supply) or blocking (impossibility of production owing to the over capacity) could occur in some chance, hence, both storages (WBS, PBS) are integrated as a prevention. This system is called integrated storage. In this paper, we suggest the simulation model of ‘WBS-PBS integrated storage’ and methodology of operation considering both ‘Color grouping’ and ‘Option leveling.’

Many enterprises are performing the effective database applications with VAN(Value Added Network) or WAN(Web Added Network) . But it is very difficult and expensive. So we suggest low-cost database system within long distance area through personal computers. This system is very powerful for flexibility. It may be estimated it's value highly because they develop the program without high programming skill. This study would be used between company with company and/or between branch with branch, for example, customer claim information, inventory information, product order etc. It is important not importing document but importing data in document. Then end-user can accomplish analysis and decision-making with their own database. It would enhance productivity in many enterprises.
