Speaker 1:	Okay. This is our game, and we are going from here over there. I clicked on Job Arrival. We know that we need to finish the job in one day. In that case, we will get $1,000, but if it goes to three days, we collect nothing. Therefore, for example if I'm doing it in 1.5 days, because it goes from one day to three day from 1000-0. In 1.5 days, I will lose 25% of what I could have got. In 1.5 day delivery will lead to $750 revenue and two days delivery will lead to 500 revenue. Don't forget, we need to pay 10 times 60 equal to 600 for raw material. We should be very careful to deliver in one day or less. This is arrival of the orders. I can download it. Here it is, and I can copy it and paste it into another file. This is a different game of the same nature, but of different numbers. I can copy it. That was my input incoming orders. I copy it in Column B. Now, here I go and look at completed jobs. I plot the completed jobs. These are the orders that I have completed, and I download. I put it into the next column. Column B is arrivals orders. Column C is orders completed. I go to Station 1. It has only one machine, I plot utilization. These are utilizations of Station 1. I only have one machine over there, copy it and put it under U1. The number of the game that you are playing are different than these numbers, but the philosophy is the same. Utilizations of Station 2, this is the graph download. Station 3 each machine is $100,000, if you sell it $10,000. These are utilization of Station 3. Now I have utilization of all three stations. I also have input and I also have output and I explain to you how to use inventory average inventory using input and output. Now, I compute the average of each 50 days, input 3.06, output 2.88 per day. Average inventory 218 and utilization during this period, are these numbers, 0.35, 0.51, and 0.39. Utilizations are quite low, fine numbers. It means at the beginning, we perhaps don't need to buy a machine, but we also need to look at the later utilization. Average utilization Station 1 about 36, and that is throughput of the system divided by capacity of Station 1. Throughput does this. We can have output as a throughput, input as a throughput or average of those as a throughput because we are trying to estimate. We cannot have the exact numbers. We don't know what the exact numbers are. We are just trying to estimate. We select output as our throughput. Throughput 288, utilization 0.355. Therefore, one equation one unknown, the only thing we need is RP. RP is R divided by utilization because we can take RP from one side, put it in our side. RP is equal to throughput divided by utilization. I have both of them, 2.88. The output, we assume it as throughput, utilization is 0.36 and RP is computed easily. Something around 99, per what? Per day. Why? Because 2.88 was per day, equal to 2.88 divided by utilization. Therefore, the capacity is something around 8.1. That is capacity of the first cessation. I never click on it. I lock the first one to be able to copy to the right and compute the capacity of the others, 8.09, copy to right, 5.61, 7.36, but there is a trick. For first and third decision is correct, but there is a trick for second fix it, find it.
