$2-$ Consider an assembly line with three machines: machine $1,$ machine $2$ and machine $3.$ Machines $1$ and $2$ are parallel and machine $3$ is series with machines $1$ and $2.$ The raw material enters to the production line with an exponential distribution, an average of $4$ minutes. The raw materials will be then sent to the queue and wait in the queue to be processed on either machine $1$ or $2.$

The raw material waiting in queue will be sent to either machine $1$ or $2$ as these machines have same functionality. Once raw materials are processed by either machine $1$ or $2$ then they will be sent to the waiting line $($queue$).$ Then the items from queue will be sent to machine $3$ for final process. The items finally will be collected by the end of line. There is a dispatcher that dispatches $2$ operators. The dispatcher responsibility is to dispatch $2$ operators to pick up raw materials $($boxes$)$ from first queue and drop boxes on machines $1$ and $2.$ The setup and processing time of machines are given below:

Simulate the assembly line explained above and submit the FlexSim file. $(15$ points$)$
