The issue of the adjustment problem for process creating a drift and a dispersion on the characteristics of their products is placed. The known methods of SPC and SPA for multi-input and multi-output processes are briefly recalled. The very general form of the direct variational model for such processes is given. The proposed statistics and selective adjustment method is presented with this general form of direct model. It is then used to steer, thanks to the CoSelect software which implements it, the simulation of a production of 150 pieces. The results are compared to those obtained with a steering by the pseudo-inverse model that can be built for this production. An Internet link allows to download the CoSelect 2.0 software.
