For the progressive notching and forming die, analyzing beforehand according to the interpretation of thin plate molding for massive production is essential. In this study, we dealt with Ez5 particularly its strip layout design based on the exported die as ordered by Japanese S automobile company's local factory in the USA. We completed the strip layout design consisting of 13 processes by optimizing the blank layout with arrays of a single carrier with wide width drawn in 1 row. This type of die is expected to be ordered in bulk frequently and at the same time via the Internet; any company with die technology will be required to cope with such type of die.

미쓰비시(삼릉)전기는 1999년 5월치바현 이치가와시 동빈에$''$특정가정용기기재상품화법(통칭 : 가전리사이클법)$''$에 대응하기 위하여 일본국내 최초의 전기제품 리사이클 플랜트를 가동시켰다. 이 플랜트에서는 종합전기메이커로서의 특징을 살려 연소를 수반하지 않는 철저한 머티어리얼 리사이클, 물을 쓰지 않는 완전건식에 의한 소재(素材)의 분리$\cdot$분별(分別)을 실현하였다. 최대의 특징은 수(手)작업에 의한 부분분해와 기계분해(파쇄에 의한 소재분리)를, 리사이클률, 경제성, 환경부하성의 3가지 관점에서 조화를 시키고 있는 점이다. 본고에서는 리사이클 플랜트의 개요를 소개하고 리사이클률 향상과 리사이클 처리비용 저감을 위해 대처해 온 다음의 3개 항목에 대하여 기술한다. (1) 플라스틱찌꺼기(殘材) 리사이클설비의 개발 주파쇄분리(主破碎分離) 프로세스에서 배출되는 금속과 염화비닐을 포함한 플라스틱찌꺼기를 처리하여, 플라스틱을 고로환원재(高爐還元材)로서 유효 활용할 수 있도록 하였다. (2)효율적인 물류(物流)레이아웃 및 수해체방식(手解體方式)의 설계 공장내의 폐제품(廢製品)$\cdot$분별물(分別物)에 대한 보관장소, 반송수단$\cdot$경로를 최적 설계하여 처리비용을 요하는 수해체 작업을 효율적으로 할 수 있도록 업무흐름을 설계하였다.

The marine leisure industry in Korea has been the focus of the power of economic growth and the creation of jobs in recent years. In this regard, many studies concerning marine leisure are on-going in various fields. In this paper, developed a layout system and algorithm can resolve the factory and facility layout problem. For a layout design of leisure-boat factories, the leisure-boat production process is analyzed in order to derive standard production space elements for the layout of the factory. Based on the results, a draft design of the factory layout is carried out based on the manpower planning data, as well as the characteristics and relationships of each process data. A layout design of this paper can be verified through a factory simulation solution and we suggest the verification method using a SBD(simulation based design) methodology. The layout system takes into account the user's accessibility and extendibility, so it is web-oriented and uses RIA (rich Internet Application) technology. Furthermore, the system and layout algorithm of this paper are verified with samples data that show the efficient factory arrangement and practical application method.

In manufacturing productivity analysis, understanding the intricate interplay among factors like facility performance, layout design, and workforce allocation within the production line is imperative. This paper introduces a simulation-based methodology tailored to food manufacturing, progressively expanding scenarios to analyze production enhancement. The target system is a food processing plant, encompassing production processes, including warehousing, processing, subdivision, packaging, inspection, loading, and storage. First, we analyze the target system and design a simulation model according to the actual layout arrangement of equipment and workers. Then, we validate the developed model reflecting the real data obtained from the target system, such as the workers' working time and the equipment's processing time. The proposed model aims to identify optimal factor values for productivity gains through incremental scenario comparisons. To this end, three stages of simulation experiments were conducted by extending the equipment and worker models of the subdivision and packaging processes. The simulation experiments have shown that productivity depends on the placement of skilled workers and the performance of the packaging machine. The proposed method in this study will offer combinations of factors for the specific production requirements and support optimal decision-making in the real-world field.

Simulations have been used to evaluate the efficiency of logistics or manufacturing systems and predict the outcomes of the systems. New simulation models are needed to evaluate new alternative plants and layouts during the resource design process. Although it is easy to handle minor changes in parameters by modifying a simulation model, it takes considerable time and effort for simulation modelers to alter the layout, which involves changes in many simulation sub-models. Therefore, this study proposes a method to transfer information in AutoCAD layout to the simulation model automatically. This study also defines a standard document as an Excel Form, and suggests a method to transfer information on the basic layouts, processes, resources, and workers to a simulation model automatically. A simulation tool, called Tecnomatix Plant Simulation 9.0, was used for this study. The proposed approach in this study was applied to a semiconductor wafer factory for a case study.

This study presents a plant concept design for a smart factory which is mainly targeted to machine airplane parts. The plant layout is based on the TOC-DBR approach together with autonomous distributed factory control considered, while discrete event simulation is also performed in order to validate its layout. The resulting layout and its procedure turn out to be quite a useful guideline in realizing those smart factories especially for machining-oriented manufacturing industries.
