Productivity and quality stability are very important competitive factors in PCB manufacturing lines that process the multiple types of products with the mixed process flows under frequent order information changes. MES is an appropriate IT solution to solve these problems in the medium-sized PCB manufacturing company. This paper introduces the MES development and its effects for a medium-sized PCB manufacturing company. The main functions of an implemented MES are delivery simulation, production scheduling, and production process monitoring. Productivity are improved up to $10{\sim}20%$ and manufacturing lead times per order are shortened up to 2 days according to the manufacturing scenarios.

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.

Manufacturing Execution System (MES) is a system that companies can use to measure and control critical production activities. This paper shows case study of implementation of MES (Manufacturing Execution System) and its methodology in a medium sized production company. This study focused on two important things in MES implementation. First, it provides critical success factors (CSFs) and construction method for success of MES implementation. Second, it presents guidelines for MES implementation in small and medium-size company. Some of the benefits with regards to MES implementation and its results are introduced in the end of this paper.

본 연구는 국내 중소벤처 제조기업의 조직성과를 달성하는데 있어 전략지향성의 선행변수와 기업가정신을 조절변수로 하여 이들이 기업성과와의 구조적 관계를 고찰하는 것을 연구의 목적으로 한다. 본 연구를 위해 국내 중소벤처기업 중에 수출실적이 있는 205개사를 대상으로 구조방정식모형으로 실증연구를 실시한 결과 첫째, 경쟁지향성과 기술지향성은 각각 기업의 성과에 긍정적인 영향을 미치지만, 고객지향성은 유의하지 않은 것으로 나타났다. 둘째, 기업가정신에 따라 전략지향성이 기업성과로 연결되는 경로에서 통계적으로 유의미한 차이가 부분적으로 있음이 검증되었다. 이는 중소벤처기업의 경우 고객지향성보다는 경쟁지향성과 기술지향성이 조직의 성과에 매우 큰 역할을 담당하고 있다는 시사점을 제공한다. 이러한 연구결과를 통해 향후 중소벤처 제조기업들은 경쟁지향성과 기술지향성을 더욱 강조하고 이와 관련된 기업가정신의 조절변수의 작용을 이해함으로써 더 높은 기업성과를 얻을 수 있을 것으로 기대된다.

High temperature operating test, temperature humidity test and temperature cycling were performed at various test levels for solid aluminum electrolyte capacitors made by domestic manufacturing company and foreign advanced manufacturing company. It was found that main failure mode of solid aluminum electrolyte capacitors was the decrease of their capacitances. The decrease of their capacitances has the same pattern in these tests. Test result for comparison of characteristics between domestic products and foreign advanced products shows that domestic products have the shorter lifetime and their capacitances decrease more rapidly in high temperature operating test and temperature humidity test. Also in these tests, accelerated tests for high temperature operating test and temperature humidity test were developed.

To shorten product development time and cost, integrated information managements of product, manufacturing process and resource are essential. In the area of material addressing, process engineers should make their decisions in the manner of collaborative engineering in order to reduce the manufacturing preparation time and cost in the product development and production. A digital virtual factory which is an united digital model of entire factory could be very useful for these areas. In this paper, the digital virtual factory is constructed and used for material addressing and analysis of an automotive general assembly shop. We developed the material addressing system for automotive general assembly shops using digital virtual factory models and nesting algorithms, and applied it to realistic problems of a Korean automotive company as an convenient and effective way of material addressing.

Digital Manufacturing is a technology to facilitate effective product developments and agile productions by digital environments representing the physical and logical schema and the behavior of real manufacturing system including manufacturing resources, processes and products. A digital factory as a well-designed and integrated environment is essential for successful applications of this technology. In this research, we constructed a sophisticated digital factory of an automotive company’ general assembly shop by measuring and 3-D CAD modeling using parametric methods. Specific parameters of each objects were decided by object-oriented schema of the general assembly shop. It is expected that this method is very useful for constructions of a digital factory, and helps to manage diverse information and re-use 3D models.

A new approach to sintering loose packed, coarse aluminum alloy powder to full or near full density is presented. A controlled amount of water vapor is introduced into the sintering atmosphere, which disru pts the oxide film and allows metallurgical contact between particles. In addition, supersolidus liquid phase sintering is used to sinter the part to full density. Since the method is particularly applicable to uncompacted powders, it is potentially useful for sintering aluminum powder preforms manufactured by 3DPrinting and powder injection molding.

Although manufacturing cost is a major part of profit in a company, it is difficult to be calculated by an analytic method. Besides, the manufacturing cost gained by simple financial structure dose not have an important meaning in market place. Therefore, an analytic method of computing the manufacturing cost is very necessary in manufacturing system. In this study, we suggested the direct cost analysis model which are able to measure accurate cost analysis of product in manufacturing system. The direct cost analysis model is made up of directly used expenditure for unit product. Also, system performances are put in the manufacturing cost analysis model so that it could be possible to analyze the change of manufacturing cost as system performances change. At the end of this paper, it verifies its relevancy and practicality of the suggested direct cost analysis model through the case study, using real data for direct labor cost.

대규모 3D 컴퓨터애니메이션의 제작공정은 제작기술의 발전과 예산의 대규모화로 인해 그 구조가 더욱 복잡화, 세분화, 되고 있으며, 프로덕션타입, 제작규모, 제작방식과 같은 유형에 따라 제작 파이프라인의 형태가 다양하게 변화되고 있다. 하지만, 소규모 제작업체에서는 제작 파이프라인의 개념과 그 구성에 대한 변화와 발전이 미비하여 이에 대한 재조명이 필요할 때이다. 이러한 연구의 배경을 주목하여 본 연구는 국내 소규모 3D애니메이션의 제작 파이프라인에 대한 이해를 돕고, 소규모 국내 프로덕션 실정에 맞는 3D애니메이션 제작 파이프라인의 구성 방안을 모색 하고자하는데 그 목적을 가진다. 본 연구에서 제시하는 소규모 3D애니메이션의 제작 파이프라인 구성 모델과 방법론은 프로젝트의 성향이나 주변 환경에 따라 충분히 변화 가능한 것이기 때문에 절대적인 것만은 아니며, 3D 컴퓨터애니메이션 제작 파이프라인의 구성을 위해서는 그 목적을 충분히 이해하고, 프로덕션내의 작업자간의 정보의 공유가 충분히 이루어질 수 있도록 소규모 프로덕션의 환경을 고려하여 상황에 맞추어 구성 할 수 있는 방법이 될 것이라고 생각한다.
