본 연구는 MRP(Material Requirement System) 시스템의 기본 요소인 BOM(Bill of Material)의 효과성 분석을 목적으로 한다. BOM은 부품의 구성 관계를 나타내는 표로서, 근자에는 모듈화의 개념이 도입된 Modular BOM이 제시되고 있다. Modular BOM은 부품의 구성 관계를 모듈화 함으로써 이들을 보다 편리하게 관리하고, 기존에 사용되어 오던 구조형 BOM의 불편함, 단점 등을 보완한다. 본 연구는 기존의 구조형 BOM과 modular BOM을 데이타베이스 관리면에서 분석함으로서, 모듈화한 BOM이 데이타 관리면에서 지니는 효과성을 분석하였다. 데이타 관리의 효과성 분석은 BOM 데이타 관리면에서 지니는 효과성을 분석하였다. 데이타 관리의 효과성 분석은 BOM 데이타베이스의 제품구성을 관계형 데이타베이스의 레코드 (또는 tuple)로 표현 함으로서, 특정 부분품으로 구성된 완제품들을 나타내기 위해 필요한 레코드 수를 기초로 하여 수행되었다. 이상의 논리에 근거하여 본 연구는 다음과 같은 데이타 관리 관점에서 분석한다. 1. 제품구성 표시를 위한 BOM 데이타베이스의 구성 레코드 수의 비교, 2. 새로운 제품의 추가나 기 제품의 제품구성 변경에 따른 갱신의 용이성 본 연구에서는 분석의 편의를 위하여 BOM 구성이 레벨을 무시한 단순형태의 2단계 BOM을 분석 대상으로 한다. BOM데이타 베이스 관리의 효과성은 제시된 레코드 수에 기초하여 데이타베이스의 규모와 변경 용이성의 측정 모형을 수립하고, 이들 모형을 modular BOM과 구조형 BOM에 적용함으로서 수행 되었다.

Since past till now, automotive wiring harness has been designed and produced under the method of part number list. However, the number of options has increased gradually on the basis of customer's needs and car manufacturer's policy, thereby bringing about an increase in the number of classified parts. Because of a large number of classified parts, cost estimates for manufacturing and production planning are more important than ever. However, the pre-existing manufacturing bill of material abbreviated as BOM is only focused on the list of materials used for actual manufacturing, and as such there have been limits to other fields or areas of usage except for manufacturing. In essence, the present paper is concerned with our study conducted on modular BOM as one of planning BOM. On such basis, we have been able to completely use a method by which to have access, make an option units' calculation in wiring harness manufacturing, and build an efficient system for cost estimates in manufacturing as well.

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.

The BOM(Bill Of Material) contains various important information for establishing production scheduling and purchasing process. For effective and efficient constructing of the BOM, some methods, such as, conventional BOM, Modular BOM and Generic BOM are developed. Many companies input the BOM information with manual process. During this process, no one can avoid human errors, that is input error and to omit input necessary Information. We must to remove the possibility of these human errors, and to construct BOM effectively. To do this, we try to take the BOM from CAD data automatically We have developed a supporting system for extracting BOM from AutoCAD files.

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.
