Explosion bills of materials of products in information systems of a production enterprise
The paper presents algorithms for the listing of information on bills of materials for assembled products. Bills of materials were distinguished into explosions: single-level, multi-level and aggregate. Bills of materials were developed using the concepts of the master and slave components. Proposed algorithms for information gathering may be cod- ed in selected programming languages and in this form used in data bases supporting pro- duction management processes in industrial enterprises manufacturing assembled prod- ucts. Application of algorithms was illustrated using an example of a furniture product.
A Study of the Performance Improvement of Bill of Material Document Sign Flow System
Due to information and network communication technology have a great improvement; electronic management flow system already can be easily implemented. It operates sufficiently with members in-groups and enhances total operational efficiency, flexibility, lean and agility of enterprise. Electronic management flow system has some important properties: information transfer, automatic flow and operation management and control. Those properties can help company to reduce cost, shorten lead time, increase productivity, and achieve a good total quality management (TQM). In the same time, it also can help company to create business competitive advantage. This study focused on the performance improvement of bill of material (BOM) documentation sign flow in A-company. To enhance efficiency and effectiveness of BOM documentation sign flow, A-company passes through information department to integrate relative documents sign of other departments to make an electronic sign program to achieve cost reduction and speed-up efficiency of BOM document sign since 2005. This case uses BOM document release to study the benefits of electronic documentation sign in product engineering department.
Wood Microbiology: Decay and Its Prevention
Introductory text on the principles of decay and discoloration processes in wood, with emphasis on the major fungal damages which may develop during the growth, storage, and use of wood. The characteristics, detection, effects, and control of microbial attacks are stressed. Provides a synthesis of the current literature on wood microbiology, a rapidly expanding field of study. (Abstractor's note: This is an important resource for conservation researchers studying the decay of wood in art and architecture.) The following is a list of chapter headings: 1) Introduction to wood microbiology; 2) Wood deterioration agents; 3) Characteristics and classification of fungi and bacteria; 4) Factors affecting the growth and survival of fungi in wood (fungal ecology); 5) Fungal metabolism in relation to wood decay; 6) The decay setting: some structural, chemical, and moisture features of wood in relation to decay development; 7) General features, recognition, and anatomical aspects of wood decay; 8) Chemical changes in wood caused by decay fungi; 9) Ultrastructural features of wood decay; 10) Changes caused by decay fungi in the strength and physical properties of wood; 11) Colonization and microbial interactions in wood decay; 12) Decays originating in the stems of living trees; 13) Biodeterioration of stored wood and its control; 14) Wood stains and discolorations; 15) Decay problems associated with some major uses of wood products; 16) Detection of internal decay; 17) Paint mildew and related degradative problems; 18) Natural decay resistance (wood durability); 19) Chemical protection of wood (wood preservation); and 20) Some trends in wood microbiology research and a new emphasis (biotechnology). -- AATA
