Which means 3*3*3=27 results

Analyzing the influences of the appearances of demand peaks

Periodic review p:

  • 1 = daily review
  • 2 = weekly review
  • 3 = weekly review

Characteristic c:

1 = Amount of money

2 = Amount of weight

3 = Amount of products

Example: Weekly review of the amount of weight sold, using Moving Averages 2

Example: Monthly review of amount of products sold, using Moving Averages 4

Improve: Recommendations

  • A project in which the accuracy of JDA is explained and measured
  • A project where it is measured / investigated how the fast moving products and their inventory levels are handled

Results (2): Quarterly Bonus

Conclusion

  • Very little variation
  • Not enough concrete demand peaks throughout the data
  • Problems do not stem from capacity

Reasons for previous excessive variation:

  • Introduction of the EPA MX-13
  • Brazil opens a PDC
