| dc.description.abstract | Although Lean Production is not a new management science, it has had a profound impact on manufacturing and production in Japan, the United States, Taiwan, and even global manufacturing powerhouses. It gradually spread from the automotive industry to influence the manufacturing management thinking of small and medium-sized enterprises. However, with changes in the global production environment, shortened product life cycles, and increasing demand for customized products, the manufacturing industry is facing tremendous challenges in balancing quality, delivery time, and cost. At the same time, with the impact of the recent Covid-19 pandemic, from the shutdown of cities and factories in China to the stagnation of consumer economies in Europe and America, the global supply chain has been disrupted by emergency orders, and the progress of information technology has brought more efficient and real-time computer computing capabilities. Therefore, the manufacturing industry also needs to rethink the combination of Lean Production and information technology to improve the efficiency of the entire production process, reduce production costs, redefine safety stocks, procurement policies, and increase production process flexibility to respond to changing economic conditions. This is a strategy for Lean Enterprises to diversify risks and bring operational performance to companies.
This study focuses on a case in the downstream semiconductor industry of substrate manufacturers. The author uses traditional Lean Production techniques such as Value Stream Mapping, research on Non-Value Added Time, the application of logistics management to reduce waste in transportation and Pull production to improve certain processes in IC carrier board production. The author also extends these techniques to the Manufacturing Excursion System (MES) information system to achieve overall production efficiency, reduce ineffective waste in the production process, reduce inventory in the process, and promote collaboration between processes. Finally, the author verifies the overall improvement results using the Value Stream Mapping analysis method. With the establishment of smart manufacturing factories like mushrooms after rain, the transformation of traditional manufacturing factories towards digitization and intelligence is an inevitable path to gradually expanding the application of related information technology with Lean Production techniques in the digital transformation process. | en_US |
