The computer systems for the decision-making must provide in a synthetic and simple way the necessary elements to the decisionmaker. That is why, it is indispensable to build Computer Human Interface (CHI) adapted to every user's perception as well as possible. The necessity to design the application data processing providing an intelligent and self-adaptive CHI seems to be therefore more and more necessary. An essential and necessary characteristic of this kind of CHI is the capacity to adjust to the environment to the user's behavior and to permit the addition of components without putting back in question the design of this one. In order to have this characteristic in an application, a modelling using intelligent agents seems to be well adapted because it permits to take into account the complexe interaction present in the CHI. Keywords. multiagents systems, adaptive systems, computer human interface.
