Mass customization (MC) is a business practice that aims to provide customers with customized products and services at near mass production efficiency. To achieve the aim, a number of methods to implementing MC are proposed. However, most of them require changes in entire process of the company, which make companies hesitate to implement MC even if it is essential to survive. In this paper, we proposed alternatives to partially implement MC for quick adaptation of MC. The base line assumption is not to change the production lines. The pros and cons of alternatives are given by qualitative and quantitative evaluation. Especially, by giving radar chart analysis of the quantitative measures, we give insight on the changes in the business performance measures, such as time to market and cost. Proposed alternatives are based on sub-processes such as purchasing raw materials, production process changes and packaging for efficient logistics. In this way, companies are able to provide customized products with small changing of the current manufacturing system. The process and benefit of the proposed strategy is verified by real world cases of a Korean health food company.

In this study, in addition to non-technical innovation activities such as organizational innovation and marketing innovation, the purpose of this study was to verify through empirical analysis what mechanism appropriation affects the business performance of a company. Data were collected from the 2018 Korean Business Innovation Survey: Manufacturing Sector and used as analysis data. As a result of the analysis, it was verified through empirical analysis that non-technical innovation improves management performance, appropriability is affected by non-technical innovation, and acts as a mediating factor between management performance. Through this empirical analysis, it was derived that considering appropriation along with non-technical innovation on the recently studied non-technical innovation can be a meaningful study, and since securing such appropriation is an important factor in determining the business performance of a company. Companies need insight into the strategic use of technology protection measures to secure appropriation. As a limitation, it was limited to studies that verify that it has a mediating effect of non-technical innovation and appropriation, and it is considered that it is possible to develop a study that affects the management performance of a company through more various verification methods for future studies.

In order to build a new factory, we must have answers regarding the following questions; 1. what is to be produced? 2. how are the products to be produced? 3. how much of each product will be produced? The answers are related to product-design, process-design and capacity-design respectively and they are used for layout-design as the input data. Especially capacity design decision provides the information regarding the number of equipments required and the balance of the line. This paper introduces a case study on the capacity design for a new factory where the retainers of ball bearing are manufactured. A simulation model is developed with ARENA for analyzing the system considered. The major objectives of the study are evaluating the performance of the line which is originally suggested by the company, and finding out alternatives for improving the system. Number of WIP between the processes are also investigated because it affects the space planning of the layout.

BOM(Bill of Materials) is a listing or description of raw materials, parts, and assemblies that define a product. In manufacturing companies that produce various products with short life cycles, it is very important to manage the BOM of products with various options and versions efficiently. BOM information should be required to share among the departments of engineering, production control, material purchasing, cost management, and shop floor within a manufacturing company. In order to share BOM information efficiently, information system based on WWW(World Wide Web) should be developed. Thus, this paper models and implements Web-based Generic BOM Management System (WGBMS) for management of a number of variant products which are consisted of standard parts under ATO(Assemble To Order) production environment. Also, object-oriented methodology was used to model a generic BOM and phases of navigational design and interface design were introduced to implement the prototype of WGBMS. And Object-Relational Database Management System (ORDBMS) was used to construct the WGBMS database.

Co-cured composite materials has its own characteristics, so its thermal expansion is different each other. The selection of tool material for co-cured composite part in high temperature more over $350^{circ}F$ and 50 Psi pressure have to consider part thermal expansion, size, shape, and economic aspect in production line. So it is important choose tooling material in manufacturing composite parts. We called the tool for airplane composite parts as BAJ (Bonding Assembly Jig). Composite parts are cured on the BAJ in autoclave. BAJ have to stable at high temperature over $350^{circ}F$ and 50 Psi pressure, Considering composite parts' dimensional tolerance compare to heat up in autoclave. This paper come from the results of the experiment at the composite parts production line and review other aircraft company's method for tooling This is for the engineer engaged in composite parts manufacturing.

In this paper, the computer simulation analyzed the effective plastic strain and temperature behaviors. The quantitative analyses which proposed the effective mold design of S/CAM shaft was executed. The parameters of forging shape that affected on the optimize conditions that was calculated with simple equation were investigated. it is expected that the developed analysis model and design technique would greatly contribute to the drum brake optimal design considering effective plastic strain and temperature affected behaviors. This development could save more than 20% of production cost and reduced failure rate to more than 30%. By improving the life span of mold from 15,000 to 25,000, financial difficulty of company imposed on a mold manufacture could be overcome.

In dies manufacturing industry, quality, cost, and production leadtime are very important. In this study, we describe the current status and characteristics of dies industry in Korea. AS a case study, we introduce a CIM system implemented in a leading dies manufacturer and describe its components and functions. Subsequently, we analyze the effectiveness of the CIM system by using the real data between 1987 and 1992 from the company. It is indicated that the most significant impact of CIM is the reduced cost, followed by increased sales, reduced leadtime, and improved quality of dies. All these four variables show positive correlations with one another. However, the data indicate that the number of employees are not directly related with other variables : probably because additional personnel are required for operating new technology such as CAD/CAM and information network.

The purpose of this article was to understand the individual proportion of quality costs which have been expended by manufacturing industries in Seoul and Kyunggido district. The collected data on 72 firms could be use for an empirical analysis and the ratio test was implementented with the questionnaires. The finding were as following : by conparison with the proportion of quality cost in typical manufacturing industrial of U.S., We concluded that total quality cost was occupied with a small portion of sale. Also as compared with the individual item of quality cost, it was noted that the proportion of prevention cost had increased in a relatively large company.
