Abstract: Manufacturing is often seen as a sector in which developing nations can prosper, since wages and production costs are lower. However, without appropriate infrastructure and technology, this is not the case. If we see most of the local manufacturing industries, they are greatly affected by market deficiency, shortage of raw material, obsolete technology and machinery, large in-process inventory, high material handling cost, poor product quality etc. On the other hand, in today's business environment (globalization), the competition is with giant external companies that possess highly advanced technology, capital and management capability with strong market network, well-developed infrastructure, skilled professional workers, and effective governmental services. Therefore, manufacturing industries should constantly search improved manufacturing methods that enable to produce high quality products at lower costs. One of the advanced manufacturing systems that help to decrease the production cost by reducing material handling and other tangible or intangible costs is Group Technology (GT). In this paper, the concept of group technology is thoroughly discussed, and as regarding to this concept, general assessment of the current situation of local manufacturing industries is carried out. To see the practical significance of GT to local industries, the researcher has taken Hibret Machine Tool Engineering Complex as a case, and to analyze the current situation and manufacturing trend of this factory, several relevant data are collected. Then based on the theories and principles of GT from different literature resources, and the analysis of the data obtained from the factory, Program aided GT based parts coding and part design storage and retrieval model and part family and machine cell formation is developed. Finally the result of this research indicates that, by the implementation of the newly developed program aided GT based parts coding and cellular layout, the factory can reduce the parts design time by 78.57%, the material handling cost by 25.4%, and the setup time as well as throughput time will be reduced by 40%.
