The continuous search of the reduction of the supplyes to the inside of every business truth (fig. A), has caused but, which directed consequence, a spropositato numerical increment of the operations of supplying and, therefore, of the relati to you costs to they associates (fig. B ).

Figure n. 2.6 - Evolution in the time of the supplyes, supplyings and costs (Unitec source, 2001)

With the solution of the integrated supply and the Virtual Warehouse offers from UNITEC instead, a possible point of equilibrium between the minimal level of the supplyes is studied (calculated based on uses of same in relation to the business productive ability and the time of escape of the orders from part of the suppliers) and the relative number and cost you to supplyings (fig. C).
