Add Variability to Arrivals

In our example, we assume our Electronics Mfg Process is dependent on a supplier to deliver the Assy entity. Therefore, we cannot always assume the supplier will be able deliver exactly 40 units a week to our process at Op 10 Clean and Prep.

Therefore, we will define a distribution for the arrival of Assy to Op 10 to reflect this variability.

  1. Open the Arrival Property dialog for the arrival of Assy to Op 10 (right click on the connection between Assy and Op 10, and choose Properties.)
  2. In the Quantity Per Arrival field, change the fixed value of 40 to the distribution U(40,5).
