Use the longest work element rule to balance the assembly line described in the following table and figure below so that it will produce 45 units per hour. Time (sec) Work Element A B 20 D B 71 (E 13 40 - IO TO OU 1 Immediate Predecessor(s) None B B E B A G F 35 71 20 40 13 65 50 26 17 8 10 355 35 K 50 65 10 H 26 IG D, JF K Total 17 8 S a. What is the cycle time? 80 (Enter your response as a whole number.) unit b. What is the theoretical minimum number of workstations? 5 stations. (Enter your response rounded up to the next whole number.) c. Using the longest work element rule, which work elements are assigned to each workstation? Work elements A, H, I should be assigned to Station 1. Work element(s) B should be assigned to Station 2. Work elements G, C should be assigned to Station 3. Work elements D, E, J should be assigned to Station 4. Work element(s) F, K should be assigned to Station 5. d. What are the resulting efficiency and balance delay percentages? (Enter your responses as percents rounded to one decimal place.) The efficiency is % The balance delay is % e. Use the shortest work element rule to balance the assembly line. Do you note any changes in solution? Which work elements are assigned to each workstation? Work elements (6) should be assigned to Station 1. Work element(s) (7) should be assigned to Station 2. Work elements (8) should be assigned to Station 3. Work elements (9) should be assigned to Station 4. Work element(s) (10) should be assigned to Station 5
