Information conservation in the divergent process has always imposed important constraints. In the Wood industry, in which the problem is present, has no solution to conserve information all along the wood life cycle. This thesis goal is to validate the use of two new paradigms allowing improving the information conservation: the communicating material and the virtual manufacturing. With the first one, the wood material is intrinsically marked with chemical product which can be identify with the Nuclear Quadrupole Resonance and allow conserving the material origin. With the second one, it is possible to anticipate sawmill production by foresee the final product characteristics.
