  • 본 논문은 다품종 소량생산에서 발생하기 쉬운 제품들의 유사성을 근간으로, 제품들의 공통적인 특성을 관리하기 위한 Famiiy BOM 체제를 구현하여 이를 제품의 설계정보관리에 이용할 수 있는 시스템 개발에 관한 것이다. 이 Family BOM을 통해 기존의 개별 제품별 BOM이 가지는 한계를 극복하고 유사 제품을 군으로 묶어 이들의 공통된 특성을 제품의 설계시에 활용할 수 있다. Family BOM은 부품을 군으로 분류하고 이 부품들의 구성을 공통 부분과 선택 부분으로 모듈화하여 표현하는 방법이다. 이 Family BOM을 통해 기존의 제품별 BOM을 별도로 관리하는데 따른 BOM 개수의 증가, 관리 및 변경의 복잡, 데이터의 정확성 부족 등과 같은 문제점을 해결할 수 있다. 본 연구에서는 먼저 부품을 형상 및 공정, 기능의 유사성에 따라 군별로 분류하기 위하여 부품의 특성을 코드화하여 이 코드의 유사성 정도에 따라 분류하는 Classification & Coding system을 개발하였다. 이 기법을 이용하여 유사한 부품을 군별로 관리할 수 있고 이를 통해 기존부품정보를 신제품 개발에 적 용하여 설계에서부터 공정계획 수립까지 시간을 단축할 수 있으며 체계적으로 도면을 관리 및 분석 할 수 있다. 또한 제품군별 BOM관리를 위한 Family BOM을 구현하였고, 이에 따라 도면 중심의 설계정보관리시스템을 개발 하였다.

  • This paper focuses on a BOM(Bill of Materials) management problem for a small and medium manufacturing company that produce automobile parts. Automobile part's manufacturers produce various products due to various automobile characteristics such as types, colors, and the other options of car. These products are classified into product groups with common parts. And each product group is regarded as a product family. This paper proposes an efficient and effective EXCEL-based BOM management scheme using characteristics of the product family. And we have implemented the practical EXCEL-based BOM management system for real small and medium automobile part's manufacturing companies.

  • This paper proposes an efficient and effective BOM management scheme for small and medium manufacturing (SME) companies that produce automobile parts. Automobile part's manufacturers produce very various products due to various automobile characteristics such as types, colors, and options of cars. These products are classified into product groups with common parts and like this product groups with commonality are regarded as product family. This paper proposes a BOM data model for product family structures and implements the practical EXCEL-based BOM management system for real small and medium manufacturing (SU) companies that produces automobile parts.

  • Today, customer-requirements are getting various, so manufacturing companies face many problems to reflect them with its' new product development or product variety. As the product model managed by companies is more increasing, there might be much more selection conditions and many kinds of parts requited for it. With those reasons, it demands many different kinds of BOM information for new product development and product variety. Under the those manufacturing environment, we can realize that lots of current products have shared many design property and common parts with those of old version. This thesis present these new products for common characteries are classified design property and common parts with those of old version. with product family and it define with modelling language which is Generic BOM. The suggested prototype programmed with Power Builder 6.0 and Ms-SQL is to help companies manage common parts and develop new product effectively by classifying product family's basic characteries with basic and changable levels.

  • Modular BOMs are typically used in TWO-Level Master Production Schedule. To solve the problems of Modular BOM generation and efficient DB construction, we proposed Value Clustering Method. Based upon Where-Used matrix of products and components, VCM is the method to find out module by generating product family group value, product value, and component value. We also proposed method to find out information about Modules, algorithms to find out Modules that show Alternative Usage Pattern, and method to find out Modules used in a given product. We also compared the DB creation method by Value Clustering Method and by conventional method. We compared the size of DB in both methods. We mathematically proved that the proposed method is doing better as the size and complexity of product family gets larger and more complicated.

  • In order to provide economic high-quality products to customers in a timely manner, companies have tried much effort to decrease the time period of engineering design and information management. As a part of this effort, we have developed the Drawing Information Management System(DIMS) based ofn GT(Group Technology) that could decrease design processing time by speedy and rational management of design processes. The characteristics of DIMS are as follows: First, the concept of Concurrent Engineering was applied to DIMS. Through LAN, reviewers are able to attach comments to dlectronic documents by anno- tation functions called Mark-up. The reviewer annotations are collected and combind with the original document to revise the documents. Second, we have developed a Classification and Coding(C&C) system suitable for electronic component parts bassed on GT(Group Technology). The C&C system makes both parts and drawing with similar characteriscs into families and helps users search existing documents or create new drawings promptly. Finally, DIMS provides the Engineering BOM(Bill of Material) using the concept of Family BOM based on model options.

  • A CIM implementation case is introduced in this paper. It is accomplished through the integration of two fundamental approaches to production planning and control; JIT and MRP. The resultant system is a hybrid where some JIT methodologies prevail, but the benefits of the MRP are also required. A new BOM structure called 'Family-BOM' is designed for the load leveled production with small lot size and the synchronized production. The overall production planning concept is described with actual data.

  • This paper is concerned with the generation and use of modular BOM, which is typically utilized in representing product configurations for two-level master production schedule. A method called VCM (Value Clustering Method) is proposed to build modular BOMS. We adopted a where-used matrix to represent part-product relationships. VCM is a method that can identify modules of components based on the where-used matrix. The method uses product family group value, product value, and component value. This can facilitate retrieving information about modules, finding out alternative usage pattern of components, and recognizing modules used in a particular product.

  • Objectives : The purpose of this study was to evaluate the effect of the family dentist system on oral health status of children and adolescents of Community Children's Centers in Busan, Korea. Methods : The subjects of this study were 81 children and adolescents, 6 to 14 years old, using Community Children's Centers. The oral health survey was conducted on the subjects from the starting stage of family dentist program in 2009 to the evaluation stage in 2010. Dental health status was examined by a trained dentist according to the guideline proposed by the World Health Organization. In addition, the information on the oral health knowledge, belief, and process of dental care were obtained using questionnaires. Data were analyzed using the paired samples t-test. Results : Percentages of subjects with fissure sealants on permanent teeth and filling rate among DMF teeth of 2010 year were higher than those of 2009 year (P<0.05). However, the rate of decayed teeth among DMF teeth of 2010 year was lower than those of 2009 year (p=0.049). Conclusions : These findings showed that the family dentist system brought a positive effect on caries prevention and proper dental care of children and adolescents of the Community Children's Centers.

  • Interchromosomal insertion of Y chromosome heterochromatin in an autosome was identified in a fetus and a family. A fetal karyotype was analyzed as 46,XX,dup(7)(?q22q21.1) in a referred amniocentesis at 16 weeks of gestation for advanced maternal age. In the familial karyotype analyses for identification of der(7), the mother, the first daughter and the maternal grandmother showed the same der(7) as the fetus's. CBG-banding was positive at 7q22 region of der(7) that indicated inserted material was originated from heterochromatin. The origin of heterochromatic insertion region in der(7) of the fetus and the mother was found in Yq12 region by fluorescent in situ hybridization with a DYZ1 probe. In the specific analysis of Y chromosomal heterochromatic region of ins(7;Y) of the mother, 15 sequence tagged sites from Yp11.3 region including SRY to Yq11.223 region was not detected. Final karyotypes of the mother, the first daughter and the maternal grandmother were reported as 46,XX,der(7)ins(7;Y)(q21.3;q12q12). All female carriers of ins(7;Y) in the family showed normal phenotype and the mother and the maternal grandmother were fertile. A healthy girl was born at term. We report a rare case of familial interchromosomal insertion of Y chromosome heterochromatin detected only in female family members with normal phenotype that was diagnosed prenatally.
