Demand Forecasts using Data Science & Artificial Intelligence

Do you play with the idea of taking your demand planning to a new level with artificial intelligence to

• optimize the collaboration between production planners and algorithms,
• reduce storage and depreciation costs,
• ensure your ability to deliver
• and save time on manual demand planning efforts?

On this page, we will inform you about what Demand Forecasting is all about. We will also introduce the relevant terminology, provide methodical insights, and more.

A typical “demand planning question” and solution

Problem
A company produces a large number of items of different types. This includes articles with regular and seasonal demand as well as articles with sporadic demand. The portfolio contains both new items and long-standing blockbusters, trendy and stable items. What is the expected quantity for each article group in the next few weeks?

Solution
The ideal solution would be a (partially) automated system producing forecasts at article group level for the next weeks and thus doing justice to the different types of planning objects. Ideally, methods from statistics as well as machine learning and pattern recognition methods are used to meet the special challenge of having both sporadic demand and regular demand patterns in the data. In addition, existing open orders are included in the forecast. A classification mechanism determines which article groups can be predicted by artificial intelligence and how well, and for which additional validation by experts make sense. An analysis at different hierarchical levels determines whether the requirements of the various article groups can be better predicted at the level of interest or, instead, top-down or bottom-up. The data is taken from the company’s ERP system, and the results of the sales planning are fed back there. The company uses its own reporting tools for the display and visualization of the results. A dashboard visualizes interim results for planners and points them specifically to those article groups for which it is worth taking an expert look at the forecasts again and adjusting them if necessary.
