Part 1 Capacity (Training)
  Runs: Mon. Feb. 22nd @9am – Mon. Mar. 1st @9am  Day 80 Bought: 1 station 1 machine; 2 station 2 machine; 1 station 3 machine; all three stations are running below 50% capacity; I don't think we need buy any more machines in near future. However, the demand is increasing in a steady rate, let's see when we need to buy more. - Jing Feb23 9:27 pm  I overbought equipments that's why we're so low in money right now. I should only bought one each for stations 1 and 3 and additional 2 equipments for station 2. Here are my observations based from my mistake: - Maximum revenue is only $10000 per day. So, if we buy an equipment that cost $100,000, it will take 10 days (10 hours) before it pays off. - I think the goal here is to complete orders within the quoted lead time. When you clicked the Customers Order Queue, the quoted lead time is 1 day. Because I overbought equipments, I have reduced the lead time from 6.6 to 0.45 days. - Station 3 took more time to complete than Station 1. You can compare both of them by taking a look at the queued kits or the utilization graphs. So, Station 2 should be adjusted to give priority to kits coming from station 3. - David Wed, February 24, 2010 8:36 am History:  I don't think you overbought a lot. Buying each of the three machines is necessay, because they are already running at full capicity before you bought it. However, the necessity of buying a third station 2 machine is doubtful, because we don't know if the second one would fully satisfy the need of order or now. It's a good idea to observe some time after each buying, and see what's the bottleneck for the growth of productivity. - Jing 9:19am Feb.24  Day 152 Observations - Lead time is still good and within the quoted - 0.62~ day. Revenue is accelerating. I mean, I look at the teams at the top and they only gained around $50,000. We gained more than $100,000 in less than 24 hours (simulation days). Cash is definitely growing at an exponential rate. So, I think we'll just do nothing 'til the last day (and hopefully we'll catch the teams at the top) - David 3:32pm Feb 26  Cash balance: (Day) 152 - 575,549  153 - 595,699  154 - 597,853  155 - 613,011  156 - 638,173  157 - 578,334  158 - 594,487
