We evoked, during chapter 5. the problems of modeling while starting with a history and a description of the principal methods of systems design of information and currents thoughs to which they are attached.
The Following is a classification of the models, Méta-models and CASE tools used in the methods for the various phases of modeling. The choice of the diagrammatic formalism of representation is guided according to "the conceptual glasses" carried by the designer.
Lastly, we approached the modeling of the activity of the company in its conceptual and organisational dimensions.On the basis of an operational CASE tool in company. The task of the leader will not only be to conceive its broader way but also the information system, to model the operation of its company considering it's dynamics and unique complexities. To analyze its risks, to conceive its strategy and to change the organization.
Data processing had impressive successes in many fields. In particular in all the operations resting on a logico-formal processing. Today, the convergence of work and the observation of the process of modeling is closely related to the process of cognition human being in its dimensions biological, psychological and social. These reflexions are of fundamental interest for the theory and the practice of the modeling of the organizations socio-économiques.(AFCET 95).
In these fields, we have a lot to gain by questioning the rational and abstract model of cognition and thus of the human behavior as well individual as well as collectively.
