Tip #003 - Empirical Distributions index

Let's say 94% of the parts produced in an element take exactly 15 seconds to process but 6% of the parts are defective and need extra work. They take 60-120 seconds to process. There are several ways to do this but the easiest is to use empirical distributions. This is how to set this up:

1. Create a distribution.

  • Select Model | Empirical Distributions
  • The first column is where you enter the percentage. In this case 94 in the first row and 6 in the second.
  • The second and third columns are where you enter the range of the desired results. In this case 'low=15' and 'high=15' on the first row, and 'low=60' and 'high=120' on the second.
  • This is what it should look like:
P[x] Low High
94 15 15
6 60 120

2. In the time field of element type in the following:
