1. The work elements, precedence relationships, and time requirements to assemble a particular product are shown below: Predecessor Element A B C D E F G H I A,B - C,D E,F F,G D Time (minutes) 0.35 0.35 0.70 0.50 0.50 0.20 0.20 0.50 0.10 a) Construct a precedence diagram of the process and label task times. b) Set up an assembly line capable of producing 2000 units of the products per 40 hour week by selecting the task with the most number of following tasks and breaking ties by selecting one with the longest task time. c) Calculate the efficiency and balance delay of the line. d) Would the answers to part (c) change, if you were to select the task with the longest task time and breaking ties by selecting one with the number of following tasks? 2. Refer to Problem 1 above. a) Calculate the maximum number of units that can be produced each week. (Hint: Use the task with the largest processing time.) b) Rebalance the line for maximum production by selecting the task with the most number of following tasks and breaking ties by selecting one with the longest task time. Assuming one worker per station, how many workers will be required for this line? c) Calculate the efficiency and balance delay of the line. 1.
