1- Consider an assembly line that consists of three machines: machine 1, machine 2 and machine 3. The raw materials enter to the line with exponential distribution of 3 minutes and then are sent to the machine 1. Machine 1 requires 4 minutes setup and the processing time for machine 1 follows triangular distribution with minimum, mode, and maximum of 4.5, 6.5, 8 minutes respectively. The items are then sent to the machine 2. Machine 2 requires setup and its setup time follows a uniform distribution with minimum of 1.5 and maximum of 2.5 minutes. The process time for machine 2 follows a triangular distribution with minimum, mode and maximum of 4, 5, 7 minutes respectively. Once the items are processed on machine 2 then they will be sent to machine 3. Machine 3 does not require setup but its processing time follows a uniform distribution with minimum of 4 and maximum of 8 minutes. There is exactly 1 operator assigned to each machine. Simulate the assembly line for 8 hours (480 minutes).
