Hello everyone,

I hope this message finds you well. I'm currently in the process of developing a probabilistic corrosion model using Monte Carlo simulation techniques. In my research, I came across a model referenced in the thesis titled "Next Generation Probabilistic Prediction Model for Submarine Propulsion Shaft Life."

While reviewing the model, I found some aspects regarding the connection between the expression and milestone to be unclear. I've attached a visual representation of the model for reference.

If anyone has insights or suggestions or any model that is similar that can be shared on how to better understand this connection, I would greatly appreciate your input. Thank you in advance for your assistance.

Best regards,

Dion

  Dion,

  Thanks for posting in the Community Forum! Without having seen the actual model you referenced, I can't say exactly what the relationship between the Expression and Milestone elements are. However, based on what I'm seeing here, I can give you a general idea of what is likely happening. The Expression element is calculating a variable that will be used in a condition that triggers an event and the event is what triggers the Milestone's time of completion. For example, let's say we are considering the "Time_Pit_Formation" expression. This is likely going to be a time within the simulation period. The Triggered Event element named "Pit_Formation" would then trigger an event when:

   Time_Pit_Formation >= {some time value}

  There could be other conditions as well. When all the conditions are met, the Pit_Formation element triggers an event that is sent to the Milestone Time_Pit_Formed. The Milestone will record the time of the trigger and also a conditional output indicating whether the milestone has been reached or not. For more information about Milestones, I recommend you see our documentation here: Milestone Elements (goldsim.com)
