The natural tendency is to keep the stock as close to the consumers as possible – if a product is not at the consumption point, then there is a (much) smaller chance the item will be sold. Only a few consumers would let their vendors ship the product to them in a few days instead of taking it right away – immediate consumption is always given preference. This is a typical push behavior: pushing the products downstream in order to increase consumption. The push behavior requires a good forecasting model, in order to predict where and when the stocks will be needed at the stock locations. However, it is a generally known phenomenon that forecasting can never be accurate!!
