Jones and Riley[9], and Hoekstra and Romme[10] studied stock location problems in considerable detail, introducing the “de-coupling point” concept. This is particularly useful in determining supply chain strategies, since it is concerned with both where and in what physical form we should hold the stock to best systems advantage. The de-coupling point separates the “pull” and “push” ideologies and ensures good customer service without necessitating the same financial commitment on the part of the supplier associated with holding finished goods stock. However, in most supply chains, upstream players still experience the worst of both worlds, because of alternating under- and overcapacity concurrent with stockpiles followed by stock outs. However, by adopting a holistic approach to total systems design, Towill and Del Vecchio[6] have shown that this situation can be greatly improved even in the absence of partnership agreements between the various “players” involved.
