In recent years, robots have been widely used to replace human labors in the manufacturing factories. In addition to use robots to work in hazardous areas on behalf of people, there are other objectives, including to ensure consistent quality, working continuously, reducing production costs to while increasing the ability to compete in the market. However, due to the high investment in robots, the most efficient operation is a strict consideration. Simulation of process improvement activities especially the robot-based production process is a subject of great interested. In this study, a simulation software, namely Flexsim is used to determine the painting process by robot to maximize productivity, reduce labor and production time for ceramic plate production. The comparison of engineering economics result was used as an indicator to select the best project.
