Presenting Simulation Results

Presenting the results of a Monte Carlo simulation can be challenging when your audience isn’t inclined to receive probabilistic information.  Decision makers often want a single number for net present value, project completion date, or profit. How do we as the modeler/analyst present this information so it is understood and appreciated for the extra information …

Interpolating S-N Data

When doing stress life fatigue analysis of spectral loading, interpolating S-N data becomes necessary.  MEboost has three methods to do this, depending on the data available. Background on Cumulative Fatigue Damage Before proceeding, let’s briefly explain why we need to interpolate.  With spectral loading, the stress cycles are varying with time.  The first step is …

The Risks Hidden in Single Point Estimates

Building a spreadsheet model for a business case, product profitability projection, etc. often entails estimating some input factors.  The estimates are often a most likely value, an estimated average, or median.  These are single-point estimates since you’re only using one number (a single data point) for each input.  Finally, you get an output number from …
