A manufacturer is designing a product layout for a new product production. It plans to use a production line for 8 hours per day in order to meet forecasted demand of 100 units per day. The product requires 7 tasks in total. These tasks are namely, A, B, C, D, E, F, and G respectively. Task A does not have any predecessor to start. To start Task B, it requires Task A to be completed. Starting tasks C needs, the task B to be completed. Also, starting task D needed task B to be completed. Task E can only start upon completion of Task C. Whereas starting task F needs the completion of both the tasks D and E. Finally, starting task G needed, task F to be completed. The processing times for tasks, A, B, C, D, E, F, and G are 2.8, 2.1, 0.9, 1.0, 1.2, 1.8, are 4.7 minutes respectively. Applying the most following tasks rule for balancing the assembly line, with ties broken according to longest task time first. What is the idleness in percentage?

Question
A manufacturer is designing a product layout for a new product production. It plans to use a production line
for 8 hours per day in order to meet forecasted demand of 100 units per day. The product requires 7 tasks in
total. These tasks are namely, A, B, C, D, E, F, and G respectively. Task A does not have any predecessor to
start. To start Task B, it requires Task A to be completed. Starting tasks C needs, the task B to be completed.
Also, starting task D needed task B to be completed. Task E can only start upon completion of Task C.
Whereas starting task F needs the completion of both the tasks D and E. Finally, starting task G needed, task
F to be completed. The processing times for tasks, A, B, C, D, E, F, and G are 2.8, 2.1, 0.9, 1.0, 1.2, 1.8, are 4.7
minutes respectively. Applying the most following tasks rule for balancing the assembly line, with ties broken
according to longest task time first. What is the idleness in percentage?
