3. Design a buffer for the assembly line (20 points) In the T-shirt manufacturing systems, the four workstations have different cycle times. If we operate these four workstations with a conveyor, we need to add a buffer as shown in the follows: Balance the Production Line You may need to consider a way to balance your production line, as shown in Exhibit 2. The bottleneck of the production line is section two. Exhibit 2 The production line of the manufacturing of a T-shirt 1 34 Analyze the critical procedure of your manufacturing system and find out the bottleneck and design a buffer to balance your production line if necessary. How could we evaluate the performance of the material handling of the procedure?
