Abstract

The aim of this paper is to present, according to a systemic analysis approach, a cereal grading system based on the Fuzzy logic techniques. Our motivation consists in proposing a model describing the information system of a grading system for cereals. An information matrix associated to a systemic analysis method was defined and elaborated. This information matrix allows us on the one hand, to identify the produced and consumed information concerning each activity and on the other hand to determine the relations between these activities.

Key words: Systemic analysis, information system, information matrix, grading system, Fuzzy logic.
