those who are in boats or trucks on the road

"Today, tense flow and stock hunting is widespread in all types of products", says Eric Hemar, CEO of the ID Logistic provider, who cites cases of crafts or the dry products of the great distribution. Everywhere we go up to the limit of the possible. "The method seeks to do out of production goods only as the needs of the consumer not tolerating, in the extreme, as circulating stocks, i.e. those who are in boats or trucks on the road. Warehouses evolve to adapt to this logic: it is to multiply the platforms say "cross docking", where the goods are to enter by a dock on one side of the building to highlight after dispatching on the other hand.

The flows strained, method which has several decades of existence, remained confined to fresh products in recent years, forced by dates limits of consumption, or to certain industrial sectors such as automotive. New, is to generalize. Philippe-Pierre Dornier, the Newton Vaureal Consulting firm, cited cases of hypermarkets, major fast food, of some electrical equipment and auto parts distributors looking to melt their reserves by night deliveries, or even multiquotidiennes.

The weight of the e-commerce

Several factors drive to this development, in particular the rise of e-commerce, very fired by consumer demand. Eric Hemar, of ID Logistic, also explains that certain provisions of the Act Galland on large distribution generated stock. However this lock jumped with the Dutreil law a year ago, which had the effect of reviving the race to the tense stream.

Many makers of "supply chains" thought until recently that the logistics management cost much more expensive in tense stream and stored streams. "But it shows that the acceleration of the flow helps reduce costs." For example, there is a direct economic and financial results correlation large distribution groups in the world and the strategic character that they gave to the logistics and the rotation speed of the flow, says Marc Peigné, Director of the Argon Consulting firm. The stock is never a safety, but always a handicap. The "supply chain managers" have now understood that they should keep only the minimum of buffer stocks.

Thus, goods travelling in a warehouse assume much more operations of handling successive (control, put-aways in paletiers of more senior, downhill for picking, controls, redirection...). In comparison, a commodity through the same warehouse in horizontal strained one truck to another stream consumes much less labour, and it is possible to process up to four times more goods on the same surface. The only cost is the information system, which must be more efficient to keep control of the continuous movements of trucks and goods.

One of the effects of this hunting in stocks in developed countries is that they are in practice pushed back upstream to producing countries more distant. "In practical terms, an international logistics provider prepares today in its warehouse based in China a command for a store in Angers, which no longer makes that pass through a"cross docking"in a port of entry in Europe", explains Philippe - Pierre Dornier, which describes the evolution of "value added outsourcing".

The schedule problem of strained flows is flows "driven" or "from". By nature, the first are rather from, as their engine is information that comes from the consumption and dates back to the plants. Or the distribution or specialized distribution still work promotion kicked or undertake by paper catalogues. They must therefore rely on extensive flows, production, to be able to feed the offers at the right time and for the duration where they are made. "But this pushed flow management is financial risk, and stocks often overflow outside the stores under tarpaulins", observes Marc Peigné. Hence the search flow combined, partly pushed, and in part by the needs of réassorts. To liberate themselves from the constraints of the drawn flow, some large textile signs supply Asia imagined witnesses stores where promotions are tested in highly focused markets. The reaction of consumers, flows are then more or less pushed or pulled. "The largest textile signs have capitalised on their brand to divest itself of the inventory and create a scarcity marketing juggling on the effect of rupture," said Philippe-Pierre Dornier.

The tension of the flow and the level of stocks remain thus an exercise in innovation standing to find the correct balance. Didier Darfeuille, group Christian Salvesen, believes for example that "advance towards strained flows has been spectacular, but that sometimes we went very far bumping into incompressible realities": "Today, the shippers seek rather secure." The accuracy and the timeliness of outweighed the shorter.
