What distribution do you use?

I'm curious.
What statistical distribution do you find most prevalent for a typical worker in an industrial process?

I'm curious to see if there are trends in the distribution and deviation, given a human worker with a saturated upstream flow (as in they're not waiting on parts to work), or if there is simply a distribution you prefer because it most closely reflects your data.


Caveat: I understand well how to perform time-studies and get the data for myself.

@Jonathan

The distribution for task times can obviously vary widely, so using FlexSim's Empirical Distribution tool with at least 30 data points is recommended if possible.


However, I would think a Weibull distribution with a shape around 1.5(skewed slightly to the right) is probably the most prevalent for task times.
