| Summary: | 碩士 === 元智大學 === 工業工程與管理學系 === 98 === The TFT-LCD market is very competitive. In such a competing environment, a company must maintain its position in production efficiency and customer satisfaction. Generally speaking, makespan is a common measurement for production efficiency, while maximum tardiness and number of tardy jobs are two criteria in evaluating customer satisfaction. This research studies the Cell process machine configuration of a TFT-LCD manufacturing company in north Taiwan. Five alternatives (including the current one) for the cell process configuration are proposed based on several experts’ domain knowledge and work experience. An experiment was conducted to compare the five alternatives with a company’s data set. A multi-objective evolutionary algorithm termed NSGAII is applied to solve the flexible flow shop scheduling problem. TOPSIS (Technique for Order Preference by Similarity to Ideal Solution) is then employed to make a choice among approximate Pareto optimal schedules. It is discovered that flexible flow shop machine layout outperforms flow shop machine configuration; in addition, alternative 5 (which provides flexible choices of processing rate) performs the best, regardless of the variation and the tightness of the job due dates.
