In an assembly plant, material handling between departments is performed using a uni-directional closed-loop conveyor. The figure below shows the layout for the modular facility, which consists of three equal-sized assembly modules (A, B, and D). one administrative module (C), and one warehouse module (E). Pick up/Drop off (P/D) points for each module are also shown in the figure.
