2. (3 pt.) The table below defines the precedence relationships and element times for a new product model to be assembled on a single model manual assembly line. Workers will operate the line for 396 min per day and must produce 300 products per day. (a) If repositioning time = 0 min, and uptime proportion is assumed to be 1.0, what is the theoretical minimum number of workers? (b) Construct the precedence diagram for this job. Use the Kilbridge and Wester method to balance the line and assign work elements to stations, applying the largest candidate rule within each column. State the maximum allowable service time Ts (min) and use the table headings shown to create the work elements listed according to columns and work elements assigned to stations. (c) Compute the balance delay (%) for your solution.
