How does this Weibull distribution look like in Flexsim?

[edward_ellis]

I did an analysis on a population of samples and the analysis said that the distribution can best be presented by a Weibull distribution such as the one in the attached picture. How would I enter this distribution in Flexsim's Weibull (i.e. num weibull(num location, num scale, num shape [, num stream])?

What would the location, scale, shape and stream nums be based on the attached picture analysis?

Thank you for the kind help!

What software package did you use to generate that analysis?

That software package is telling you to use the expression: 9 + WEIB(0.00158. 0.447)

You need to look in the documentation of the software that generated that expression to know what those two parameters mean in order to know what you should put into FlexSim.

Try weibull(9, 0.00158, 0.447) and see if you get data that seems correct. If not, then maybe you need to switch the shape and scale parameters: weibull(9, 0.447, 0.00158)

For more information, see https://en.wikipedia.org/wiki/Weibull_distribution#Standard_parameterization

You can use the Expertfit addon in Flexsim (in the Statistics menu) to check what a distribution looks like and play with the parameters to see what their influence is.
