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.
Evaluation of Impact of Yarn Count and Stitch Length on Pilling, Abrasion, Shrinkage and Tightness Factor of 1 ? 1 Rib Cotton Knitted Fabrics
This study investigates the impact of yarn count and stitch length of 100% cotton knitted fabrics. 1 × 1 ribs structured fabrics were used in this research work. The stitch length 2.50 mm, 2.52 mm, 2.60 mm, 2.70 mm, 2.80 mm and 2.96 mm were used of the yarn count of 26Ne, 28Ne and 36Ne. The areal densities of the grey fabrics were in various amounts. The impacts of yarn count and stitch length were measured concerning pilling resistance, abrasion resistance, and shrinkage and tightness factor. The result showed that the fabric pilling grade decreased while number of cycle increased. Abrasion resistance decreased but length wise shrinkage increased despite the fact that the stitch length increased. The results also exposed that the tightness factor of the fabric increased with the increase of the stitch length in both dyeing and washing state and finished state compared to grey state for the yarn count 26Ne and homogeneous result not found for yarn count 28Ne and 36 Ne.
