How does crystalball simulate requirements in excel?

Forecast by defining random input fields. The operation steps of crystalball to simulate demand in excel are as follows: first, open Excel to define random input columns, then define predicted output columns, set execution numbers, and finally perform simulation to simulate demand. CrystalBall is used in DFSS, process research, process optimization, simulation change of existing process, tolerance analysis, design analysis, raw material screening, capacity design, resource allocation and inventory optimization, restricted project screening and preventive maintenance optimization.
