Hillary & Trump Co. makes hilarious trumpets on an assembly line. Completing an order under a contract signed earlier with the Biden O'Barak Orchestra (BOO), Hillary & Trump Co. needs to produce 64 hilarious trumpets within the next 6 days. The assembly line works 8 hours a day.

Donald Hillary, Operations Manager, and Clint Trump, CEO want the assembly line to be balanced. The figure below represents the precedence network diagram, with the tasks numbered in Roman numerals and the time that each task takes to complete in minutes.

1. What should be the cycle time to complete the order from BOO? A = 6 days x 8 hours a day = 48 hours

R = 64 trumpets

Cycle time = A/R => 48 / 64 = 0.75 hours OR 45 minutes

2. How would Donald Hillary and Clint Trump balance the line if they decided to use "thelongest task time - first" rule? (Line-balancing approach)
