It would be nice for FlexSim to do a parameter check on the distributions (possibly on reset) to see if a distribution makes sense, based on values put into the parameter fields. This is especially true when referencing parameter values from a global table, where typos could be put into which cell is being referenced. Also when referencing a table value, the parameter window does not draw a histogram for the user to visually check if the distribution makes sense. One example of this is if I select a triangular distribution for processing times, then set the parameters to Min:5, Max:2, Mode:10, then all the times will be 5. The triangular distribution does not make sense, since the Maximum values is less than the Minimum value and the Mode. Other simulation software packages do test to make sure the parameters for distributions make sense before running the model and will alert the user to adjust distribution parameter values before the model can be ran.
