System Modelling of the Cereal Grading System in Tunisia

After a presentation of the cereal activities in Tunisia, we present, according to a systemic analysis approach, the cereal grading system. A model describing the functioning of complex system was established and has allowed identifying the information that ruled it. An information matrix is defined and elaborated, it enables on the one hand to identify the produced and consumed information concerning each activity and on the other hand to determine the relations between the activities.
