Sampel Block Diagram   Thank you for all the helpful replies! I greatly appreciate your time.   I tried just unselecting Show Distribution Profiler to speed things up, but calculations were still apparently taking place behind the scenes.  Unchecking the Run button did the trick, although when I eventually recheck it the calculations still take quite a while to run, even with N = 3. After the initial calculations, slowly increasing N to 7 and then to 15 resulted in much faster calculations. I did get rid of the Library object in my diagram (another complex parallel series system) and replaced it with K out of N blocks as approximations (not perfect, but still useful). That seems to prevent JMP from crashing.  I attached a similar diagram showing the complexity, just for reference. It may be the networking-style of redundancies that are taking a while to calculate. I certainly could never calculate them by hand. Thank goodness for JMP Pro! ... View more

Thanks for the quick reply Jeff.  I am in the Reliability Block Diagram in JMP Pro, so there is not a Prediction Profiler.  There is a Distribution, whichI guess is essentially a profiler, and a Reliability plot, which also is probably a prediction profiler.  Under the red hotspot for Distribution, then Reset Factor Grid, there are options for Current Value, Minimum Setting, Maximum Setting, Number of Plotted Points, and checkboxes for Show and Lock Factor Setting.  I changed the Number of Plotted Points from the default of 41 down to 5, but that didn't seem to stop JMP from Not Responding.  Each time I changed something in the block diagram JMP seemed to want to recalculate, which is fine. However, each time I added a new block, it got slower and slower. Eventually it just stopped.  I let it run overnight and it did seem to finish whatever it was doing. However, when I made another change, it went right back to Not Responding. Now the file takes a long time to open, and JMP eventually shuts down. I'm guessing I need to reduce Number of Plotted Points right away for all Distribution and Reliability plots, before adding any additional blocks. Do you think that might resolve the issue?  Again, I greatly appreciate the help! ... View more
