You just need to specify the min, max, and mode.</P><P><span class="lia-inline-image-display-wrapper" image-alt="7305-triangular.png"><img src="https://forums.autodesk.com/t5/image/serverpage/image-id/1495621i22D1CB3234F2D231/image-size/large?v=v2&amp;px=999" role="button" title="7305-triangular.png" alt="7305-triangular.png" /></span></P> Thu, 29 Jun 2017 16:45:51 GMT https://forums.autodesk.com/t5/flexsim-forum/is-it-possible-to-have-a-mean-minimum-maximum-distribution/m-p/13530844#M39742 Matthew_Gillespie 2017-06-29T16:45:51Z https://forums.autodesk.com/t5/flexsim-forum/is-it-possible-to-have-a-mean-minimum-maximum-distribution/m-p/13530845#M39743 <P>@►Matthew Gillespie</P> <P>Thank you for your fast answer. so "mode" in that case has the same meaning as "mean", am i right?</P> <P>thanks anyways, you helped a lot.</P> Thu, 29 Jun 2017 16:50:33 GMT https://forums.autodesk.com/t5/flexsim-forum/is-it-possible-to-have-a-mean-minimum-maximum-distribution/m-p/13530845#M39743 oliver_h 2017-06-29T16:50:33Z https://forums.autodesk.com/t5/flexsim-forum/is-it-possible-to-have-a-mean-minimum-maximum-distribution/m-p/13530846#M39744 <P>You can also use ExpertFit, a curve fitting program included with FlexSim, to fit a distribution to your data.
