Use flexsim to generate a simulation with $1$ machine. The output location is $120$ feet away from the machines. The input location is $200$ feet away. Jobs arrive at the rate of $1$ every $5$ minutes. The processing time on machines is $4$ minutes for each machine with an exponential distribution. You have AGV to move jobs. AGV load and unload in $20$ seconds. The speed of AGV is $2$ ft per second. How many AGVs do you need. Solve with and without simulation.
