Dynamic pricing strategies are increasingly common, particularly in online business. For the purposes of simplification, long product lifecycles and an inexhaustible stock are often assumed. Conversely, in the area of fashion it seems expedient to take into account both the product age and the stock. The product lifecycles are mostly very short in this area. In this context it is very important for the retailer to have sold out an item at a particular time if possible, as the subsequent item then appears. It is equally important to know when an item will be sold out, to reorder on cue if the item has not yet reached the end of its life.
A sporting goods retailer uses dynamic prices to control when items sell out in their online shop. A good prediction of when items will be sold out is necessary in order to make the most expedient price adjustments. The time a product is sold out depends not just on its price, but also on other product attributes, such as brand, size and product group.
The task for the participating teams is to use the sales data from a period of four months to develop a prediction model, which can be used to predict the products time of sell out in the following month. The aim is to predict as accurately as possible the precise day when items will sell out.
