본 연구는 "ICT환경과 경영성과의 관계분석"에 대하여 연구하였다. 한국의 주력산업의 경우 대기업들은 이미 상당한 수준의 스마트공장을 구축, 운영함으로써 세계시장을 선도하고 있으나 전체 기업의 95%를 차지하는 중소 중견기업은 자체적으로 스마트공장을 구축하지 못하고 있는 실정이다. 스마트공장 구축 정부지원 기업수는 총 4,891개 기업(구축완료는 3,984개 기업, 구축중인 기업은 907개)으로 구축가능 공장수의 2.9%, 미 구축기업은 97.1%(166,344개 기업)로 매우 미약한 실정으로 개선해야 할 커다란 문제점 있다. 연구결과, 급변하는 환경에 대응하여, 도전적이고 지속적인 경쟁력을 갖추기 위한 기업혁신의 일부분인 스마트공장의 성공적인 구축을 위해서는 경영자의 의지가 가장 중요하다는 이론적 체계를 제시하는 본 연구의 첫 번째 연구목적이 달성 되었다고 할 수 있다. 둘째, 스마트공장을 구축하기 위한 자금조달은 자체자금 충당뿐만 아니라 정부의 자금지원이 스마트공장 구축의 핵심요인임을 알 수 있었다. 셋째, 스마트구축에 필요한 기술은 자체기술 이외에 정부의 기술지원, 외부기술 컨설팅 지원이 매우 중요함을 알 수 있었다. 넷째, 내부 조직원의 조직참여도는 협조적이고 원활한 긍정적인 참여도 또한 성공요인임을 알 수 있었다. 후속 연구로는 기업의 운영 현황을 파악하고 문제점을 도출하여 4M1E 기법으로 원인을 분석하고 대책을 수립하여 실시해본 결과, 개선전후를 비교하고 개선된 사항을 표준화하고, 보다 깊이 있는 연구가 필요하다. 논연구는 기업의 ICT환경과 경영성과의 관계분석을 통하여 스마트공장을 구축을 위한 기초자료를 제공 하였다는데 그 의미가 있다.

Purpose: This paper aims to propose a practical strategy for smart factories and a step-by-step quality strategy according to the maturity of smart factory construction. Methods: The characteristics, compositional requirements, and diagnosis system are examined for smart factories through theoretical considerations. Several cases of implementing smart factory are studied considering the company maturity level from the aspect of the smartness concept. And specific quality techniques and innovation activities are carefully reviewed. Results: The maturity level of smart factory was classified into five phases: 1) ICT non-application, 2) basic, 3) intermediate 1, 4) intermediate 2, 5) advanced level. A five-step quality strategy was established on the basis of case studies; identify, measure, analyze, optimize, and customize. Some quality techniques are introduced for step-by-step implementation of quality strategies. Conclusion: To build a successful smart factory, it is necessary to establish a quality strategy that suits the culture and size of the company.

Presented in this paper is a case study of constructing a smart factory for aircraft parts. The construction procedure involves four phases. First of all, its management goals are set, and layout design and simulation are carried out in the conceptual design phase. In the detail design phase, operating scenarios for each module are written out, and probable risks are analyzed by expert groups, and then requirements for developing equipments and subsystems are determined with consideration for element technologies and their integration schemes into the smart factory. In the fabrication and installation phase, system development, equipment fabrication and installation are proceeded in a separate manner, and then integrated together subsequently. In the operation and improvement phase, the factory is stabilized, sophisticated and improved constantly during real operation.

The steel bars account for a high percentage of material costs for the current construction projects. At the present time, most of the construction projects for the factories of thin-film transistor liquid crystal display (TFT-LCD) complete the transactions of steel bars when the suppliers ship the steel bars to the temporary storage/processing sites. This paper applies the buy-in concept in the Theory of Constraint (TOC) on the supply chain of steel bars. In this study, suppliers are required to establish warehouses at the construction sites and complete the transactions when the formed and processed steel bars are shipped into the factory sites. The aim is to find a win-win solution to meet with the expectations from constructors as they hope that there is no need to build up inventories but supply is ready at any time. Also, this paper compares and analyzes the traditional supply/inventory model of steel bars and the Demand-Pull (D-P) model under the TOC framework. It is proved that Vendor Management Inventory (VMI) in the D-P model is able to more effectively manage steel bars as a material.

The power of semiconductor, Korea is continuously constructing semiconductor production line for keeping a front-runner status. however, studies and data about potential risks in semiconductor factory are still short. If fire does not initially suppressed, the fire causes a great damage. To decrease fire risk factors, in addition to fire fighting safety equipment, more important thing is how to design and construct fire protection system. The current fire protection codes about semiconductor factory come under functional law, and this law is short of consideration about particularity of factory. The existing prescriptive fire codes depending on experience compose without evident engineering verifications, thus equipments which is created by the current prescriptive fire code may bring about a variety of problems. For example, the design under the current regulation can not cope with the excessive investments, low efficiencies, and the diversifying construction designs and be applied to the quick changes of new technologies. Ergo, an optimal design for fire protection is to equip fire protection arrangements with condition and environment of production field. Manufacturing factory of semiconductors is a windowless airtight space. And for cleanliness, there exists strong flow of cooperation. Therefore, there is a need for fire safety design that meets the characteristic of a clean room. Accordingly, we are to derive smoke flow according to cooperation process within a clean room and construction plan of an optimal sensor system. In this study, in order to confirm the performance of proposed smoke-exhaust equipment and suggest efficient smoke exhaust device when there is a fire of 1MW of methane in the clean room of company H, we have implemented fire simulation using fluid dynamics computation.

Virtual Manufacturing is a technology to facilitate effective product development and agile production by computer models representing the physical and logical schema and the behavior of real manufacturing systems including manufacturing resources, environments and products. For the successful application of this technology, a virtual factory as a well-designed and integrated environment is essential. In this research, we constructed a sophisticated virtual factory model of an automotive company's paint shop, and performed precise simulations of unit cells, lines and whole plant operations for collision check and off-line programming. It is expected that this virtual paint shop is useful for achieving time and cost savings in many manufacturing preparation and planning activities of new car development processes.
