Multi-Objective Approach for U-Shaped Robotic Mixed-Model Assembly Line Balancing with Robot Failures

A U-shaped assembly line is one of the essential tools, which increases the production efficiency of companies. Due to the importance of the U-shaped assembly line and robotic assembly line in recent years, we merge two points into one and model a new problem as U-shaped robotic mixed-model assembly line balancing. In this study, two different modeling approaches proposed for this problem. Also, we consider three objective functions (i.e., cycle time, robot failure rate and purchasing cost of robot). An augmented -constraint method is used to solve a numerical example of the problem to show the validity of our presented model.
