Optimal scheduling of airport's runway operations. A case study in Tan Son Nhat International airport

Abstract

In recent years, green manufacturing has become more common and essential requirements considered by manufacturers and customers. As one of the most approaches, lean principles and techniques are becoming very useful to improve the productivity by reducing the wastes. Thus, it is very necessary to explore more applications of lean manufacturing into increasing the environmental performance of the systems. In the thesis, the case of recycling system in Scancom Furniture Company is considered for improving the flow of material through the systems. It takes an important part in company to utilize the unused pieces of wood which are reused and recycled for the main production. By the reason, the main purpose aims to improve productivity for this system. After that, there are two lean techniques: Eliminate Rearrange Combination Standardization (ERCS) and line balancing applied for system improvement. The main contribution provided significant improvement by reducing 45% of WIP and 41.37% of total waiting time for the systems.
