Customer order scenarios simulated.
Scenarios
Description
Base case
No changes in customer orders of 10,000 units/week, information visibility turned off, and flexible work week is turned off
Random normal
Starting week 16, customer orders vary between min of 800 and max of 1200 with mean of 1000 and std. deviation of 30
Random uniform
Starting week 16, customer orders vary in a random uniform pattern between a low of 800 and high of 1200
Random upward trend
Starting week 16, customer orders show an upward trend of 5 units/week and vary in a random uniform pattern of ±200 units on either side of trend line
Random downward trend
Starting week 16, customer orders show a downward trend of 5 units/week and vary in a random uniform pattern of ±200 units on either side of trend line
Spiked orders
Starting 26th week, every 13th week (one quarter approximately) customer orders spike up by 20% (26th, 39th, 52nd week, etc)
Dipped orders
Starting 26th week, every 13th week (one quarter approximately) customer orders dip down by 20% (26th, 39th, 52nd week, etc)
In all scenarios, FWW: flexible work week switch is turned on. IV: information visibility switch is also turned on.
