Most commercial PDM (product data management) systems, which have been released recently by overseas famous software vendors, are still expensive and heavy to apply to small and medium enterprises (SMEs). Proposed in this paper are an architecture and functions of collaborative BOM (bill-of-material) management system (cBOM-MS) which supports the internal BOM management by BOM Navigator, provides SMEs with constructing the collaborative BOM via Collaborative BOM Portal, and proposes an interface to extract BOM automatically from commercial CAD systems. In the design of cBOM-MS, BOM Navigator and cBOM Portal are positioned separately to reinforce the information security about product data during product development process.

This paper proposed the EGBOM, Extended Generic BOM, which is more flexible BOM system than GBOM. The GBOM system has the limitation to construct Result BOM and to select options by choosing only one Variant under given Cluster. In order to overcome this limitation, we propose the EGBOM which can make more various Result EGBOM, which can use to rolling stock through constructing urban transit BOM using the proposed EGBOM. The last, this paper describes the various Result BOM examples constructed from Source BOM of UT_EGBOM, such as rolling-stock maintenance BOM, individual car BOM, etc.

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.

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.

Purpose: For effective quality assurance activities, BOM-based quality assurance method is presented. This study introduces various BOM conversions such as Q-BOM, T-BOM, and S-BOM based on M-BOM structure. Methods: Product quality control via Q-BOM manages inspection/audit information, overall supply-chain of product, part requirements, and inventory status. T-BOM manages part traceability, and S-BOM enables statistical control over key process and parts at various hierarchy levels. Results: Quality plan template was developed based on the study results of BOM system including Q-BOM, T-BOM, and S-BOM. Conclusion: Through BOM(Q-BOM, T-BOM, and S-BOM) study and development of quality plan template, more systematic and comprehensive quality management plan is achieved.

Bill of material (BOM), which structurally represents the relation among parts constructing a product, is usually created when enterprises start to develop a new product. And it is shown as various types of BOM according to business needs and usage such as eBOM (engineering BOM), gBOM (green BOM), mBOM (manufacturing BOM), pBOM (process BOM), etc. eBOM, generally called BOM and created in the design stage of the new product, includes the drawing information of parts in the view of product function. eBOM is extended to gBOM adding the material information of parts to cope with international regulations for environment. eBOM is transformed to mBOM, which includes manufacturing sequence of parts and adds some parts required to fabricate parts and to assemble the product. mBOM is also extended to pBOM adding the process information of each part and additional assembly processes. This study introduces the concept of multi-BOM covering eBOM, gBOM, mBOM and pBOM, and proposes an advanced way to manage product data using multi-BOM system. The multi-BOM system proposed is to manage their relations using transformation function of BOM and master information of all BOMs.

본 연구는 WfMS라는 사용환경 하에서, 워크플로우 프로세스라는 대상 객체를 BOM(bill of material) 정보로 부터 High Level Petri net 형식으로 자동적으로 생성할 수 있는 엔진의 개발을 궁극적인 목표로 설정하고 있다. BOM은 제조되는 제품의 구조에 대한 정보를 지니고 있다. 관리 및 생산이라는 두 도메인 사이의 차이점에도 불구하고, 생산 분야의 BOM 정보의 이용방식이 관리 프로세스의 설계에도 이용될 수 잇다는 사실을 먼저 설명한다. 워크플로우 프로세스는 Petri Net의 형식으로 표시한다. 주어진 BOM으로부터 이에 대응하는 petri net을 생성할 수 있는 매핑 알고리즘을 소개한다. 이러한 이론 및 알고리즘을 기반으로 하여, 주어진 BOM 정보로부터 이에 대응하는 Petri Net 정보를 자동으로 생성시키는 프로세스 디자이너의 프로토타입을 구현하여 소개한다.

This paper describes an effective modeling and implementing technique of Generic BOM Management System(GBMS) for management of number of variant products. In this paper, OMT(Object Modeling Technique) was used to model a generic BOM and Object-Relational Database Management System(ORDBMS) was used to implement the GBMS database. In order to prove the effectiveness of proposed methodology, a case that assembles computer with various options was studied.

The Purpose of this paper is to automate the representation of manufacturing line using Petri net model. In the manufacturing cell, the line can be represented using workflow which is composed of Bill of Material (BOM) and Bill of Processes (BOP). BOP shows the precedence of processes and the relationship between assembly and disassembly. As a modeling scheme, generalized stochastic Petri net is adopted. For a problem domain with flexible manufacturing cell, Petri net model is made and behavioral properties are analyzed.
