| Summary: | 碩士 === 國立臺北科技大學 === 工業工程與管理研究所 === 99 === Information technology is emerging in the 21st century such as optical applications and information communication which requires a lot of thin film transistor liquid crystal display (TFT-LCD) panels. The development of scientific products such as cathode ray tube (CRT) displays to the TFT-LCD display brings people more convenient and joyful life. Companies invest heavy capital, labor, and equipment in the TFT-LCD industry. As the government actively develops "Two Trillion & Twin Star" industry, the image display industry is the focus of the project plan. The TFT-LCD panels produced in Taiwan hold the market share from 36% in 2002, to 39% in 2009 in the global market, which ranked second in the world. It has shown to be very critical in the international LCD industry.
In the traditional manufacturing process, the glass substrate is cut into LCD plates of same size. Due to lack of effective methods of TFT-LCD mixed production and its low yield rate, how to improve the process of cutting methods plays a critical role in LCD operation process. This study presents a two-stage algorithm. The first stage uses Particle Swarm Optimization optimal with BLF logic algorithm to find the initial feasible solution. Then, the Genetic Algorithm is utilized for optimal LCD plate cutting combination. The result will provide the minimal glass substrate waste for the LCD production.
