ResumoIn 1950 Electricité de France (EDF) began to use a method of relative profitability in choosing its production equipment. This was the so-called Blue Note method. However, the size of the investments put into play, the variety of techniques which could be used, and the major uncertainties concerning long-term development of sources of energy required the simultaneous use of aggregate programming methods. Use in the last five years of nonlinear programming has confirmed the usefulness of these methods. The problem of coherence between this aggregate (or “global”) approach and the “analytical” approach (the Blue Note) then became of great importance. This is why an extensive effort at theoretical research has been devoted to this problem, at the time when development of the economic context made it necessary to update the Blue Note. Now, following this theoretical research, EDF is able to fuse the two approaches into a single method ensuring coherence of all the decisions for choosing equipment, whether it is a matter of general management (centralized decisions) or of the multitude of small decisions taken in a decentralized way by the regional managers.
