  • Todays, there is fast transition about the new manufacturing IT methodologies from the conceptual phase into the practical application phase for the strengthening of enterprise competitiveness in manufacturing industry. One of those new methodologies is PLM (Product Life-cycle Management). PLM methodology consists of 3D CAD for the product design, PDM (Product Data Management) for the data management based on the collaboration platform and lastly DM (Digital Manufacturing). DM has evoluted from the stand-alone computer simulation of early 1980s, and now it covers the overall production development and production. Unfortunately, there exist serious critical problems about the actual application of DM for the real work. This is owing to the transition of the point of view from stand-alone type application (such as flow simulation or robot simulation) to that of business process about product development and production management. In this paper, we propose an application framework for the successful project with the digital manufacturing methodology with the concept of Information Strategy Planning, which enables the systematic diagnosis and the quantitative evaluation. Also, we introduce the actual practice of the proposing framework with the ISP project for 'Analysis & Simulation Technique of manufacturing process project' that is being conducted by Chungnam Techno Park.

  • Recently, fundamental manufacturing industry such as casting foundry, plasticity, welding etc. is rise to concerned. This study is the analysis of using structural equation method in order to verify the significant activation factor of quality management activities and the effect on business performance in fundamental manufacturing industry. To perform this research, we surveyed CEOs, managers, workers working for manufacturing business. We analysed valid 357 questionnaires that we could use for this research using SPSS 15.0 and AMOS 18.0. The results through this research is following. First, we verified the relationship between organizational supports and employee's participation to quality management activity, we could get the result that positive influence on to interrelation. Second, we analysed that organizational supports had a meaningful effect on not process performance but business performance. Third, we found that employee's participation to quality management activity had a significant to business performance, and process performance had a meaningful effect to business performance.

  • Recently, business process management has become an important concept to define and execute business process. During the execution of the collaborative business processes defined by the consensus with manufacturing enterprises, a lot of variations can be occurred by various internal and external factors related to business. From this reason, manufacturing enterprises have tried to seek for a technology to define and execute the collaborative business process systematically under the dynamic situations approving process variation. This study defines the collaborative business process among manufacturing enterprises at first and proposes its execution technology under the dynamic situations. Here, the proposed execution technology includes the authority management of each process, sub-process, and activity for security, the forced execution of the incomplete process containing the undefined sub-process, the re-execution in a certain range of business process for correcting errors, and the dynamic selection of sub-process. Furthermore, this study implements a prototype system to check the validity of its application under the dynamic situations.

  • 본 논문에서는 실시간 공정능력관리 기반의 MES(Manufacturing Execution System) 시스템과 해당 시스템을 활용한 제조 업무 수행 절차에 대해서 제안한다. 현 MES 시스템은 제조 현장을 쉽게 인지할 수 있는 KPI(Key Performance Indicator) 리포트는 제시하지만, 실질적 제조 현장의 KPI 향상을 위한 개선 방안은 도출하지 못하고 있다. 즉, 불량률 증가, 수율 감소, 생산 리드 타임(Lead-Time) 증가의 궁극적 원인을 발췌하여 개선 방안을 도출하고, 이를 제조 현장에 적용하는 부분에는 어려움이 있다. 본 논문에서 제안하는 실시간 공정능력관리 기반의 MES 시스템은 공정능력지수를 결정하는 설비 주요 인자의 산포도를 실시간으로 관리하여, 기존 MES 시스템의 한계점을 극복한 제조 운영 관리시스템 구축이 목적이다. 그리고, 실시간 대용량 데이터 처리를 위한 속도개선 방안을 제시하여, 해당 시스템이 잘 운영될 수 있도록 적용하려고 한다.

  • Recently, the strategy of the age of limitless competition for existence of manufacturing company appears for the enhancement of productivity through the automatic system, the reduction for the cost for standardization and the decision making process for the information system. Especially the critical success factors in manufacturing company can be summarized for the establishment of production visibility through the production management, material & work-in-process management, the establish of the flexible manufacturing system for the changed order priority and the establish of the quality system for improvement of product and process quality. The existing production management systems supply only simple information about production results on real time, can delay quick decision making. And it can prevent acquiring the information about various customer needs and the communication problems with other systems. In this paper, it will show MES system, a solution for the problems of existing production management systems. And through a case study of D company, it will reveal improvement effect on shipment error using MES system and economic analysis for MES itself.

  • Optimum lot size calculation for real world manufacturing environment has been focused since last few decades. Several extensions have been made to the basic economic order and production order quantity models to realize the possible practical situations in industry. However, focus on work-in-process inventory has been ignored relatively. This paper provides a comprehensive review of the models developed for group technology based manufacturing environment focusing on work-in-process inventory. Models have been extended from a perfect manufacturing conditions to an imperfect manufacturing situation considering rework, rejection and inspection. Optimum lot size has been evaluated using a simple algebraic optimization approach. Significant parameters are highlighted using sensitivity analysis for the developed models. Numerical example is used to illustrate the utilization of such models in day-to-day production setups and the impact of significant factors' variation on total cost and optimum lot size.
