1. Consider a production line with 4 machines. The raw iron bars enter to the line with an exponential distribution, on average of 3 minutes. The iron bars will be then stocked in the queue. Right after queue, there are two parallel machines, machine I and machine 2 that perform cold extrusion process. The process time for both machines follows a uniform distribution with lower and upper bound of 8 and 10 minutes. The setup time for both machines is 5 minutes. There is a dispatcher that dispatches two operators to pick up iron bars in the queue and drop them on both machines 1 and 2. The processed irons have to wait in another queue for the next process which is a metal forming process. There are two machines that perform the metal forming process, machines 3 and 4. The process time for both machines 3 and 4 follows a triangular distribution with minimum, maximum and mode (most likely) of 10, 15, 12 minutes respectively. There is no setup time for these machines 3 and 4. The finished iron bars will be then sending to the third queue and stock there before collection (hint: use sink object for collection). There is a transporter (lift truck) that moves the finished iron bar stocked in the third queue to the sink. 1. Consider a production line with 4 machines.
