| dc.description.abstract | Manufacturing firms are all facing increasingly more difficult challenges to sustain competitiveness. The challenges include increased industry competition, more stringent quality requirements, greater variety in smaller quantities of customer orders, larger fluctuations, and compressed delivery time. No matter in the electronic industries or traditional industries, the manufacturing units all have to continuously improve product quality, delivery time, production efficiency, inventory management to ensure the competitiveness of the company.
This study analyzes the replacement of MES (Manufacturing Execution System) from the original one. Based on the framework from a literature review, the analysis provides the reasons for the replacement of manufacturing systems, and the impact and effectiveness of such a replacement. The case study also shows whether the company has achieved the objectives of implementing the new system such as improvement in production efficiency, enhanced product traceability, and reduction in inventory levels.
This case study uses qualitative approach to explore the research issues in-depth from the original situation, the development processes, to the implementation stage. The study also evaluates the achievement of expected efficiency. This study shows that by flowing the exact design of the system and reforming work processes, implementing the MES can effectively reduce the human errors, improve process control, information accuracy, and production yield rate, and then decrease the operation costs. The results of the case study provide the key factors and issues that may cause the delay of MES implementation, offering implications that may help other companies in successfully introducing MES.
