Not sure, but try this link for more guidance
Not sure as I could not open your link... There is not much on the internet to reference, but I did find a few references for Rolled Throughput Yield, the following page perhaps providing more guidance than most?

Link Xue,
My initial thoughts are to take the worst case, as you appear to have done i.e. Rolled Throughput Yield = 57.6%.
How many Good v Bad parts are there from each process step?
What is "FTY"?

According to Goldratt
Starting with 100 units each at 1A1, 1B1, and 1B2 you will end up with 90 parts into process 1A, and 80 units into 1B. Since you can only process the 80 units from 1B, 10 units get left at 1A and you process 80% of 80 into 2B, i.e. 64. Yield out of 2B is 90% of 64 or 57.6. Remember, if this is a test question that assumes that you start with 100 units at the initial processes, you only get 57 at final (or 576 if you start with 1,000).
I believe that FTY stands for First Time Yield, i.e. yield through the standard process, without rework or other extra processing.
BTW, Link Xue, the 4,622 people at the Cove welcome you.
