we did extensive tests on the methods using real order data over a representative period. Here we show some results which are indicative of the general outcomes. We first deal with the stockmix determination and them we evaluate the three CS optimisation methods. Finally we compare the currently used stockmix and cutoff order sizes with the outcomes of the method percented here. The following basic figures apply to all three parts of the results. The minimum percentage of order that should be shipped via the DCs was set at 74% ,while the minimum percentage of order shipped on time was set at 95% The cutoff order sizes cuold assume any value between 0 and 100000m2
