Since the application of information and communications technologies (ICT) to agriculture is far from the potential, we investigate how to systematize the process of transformation. In this article, we propose a new approach to design intelligent systems for the management and supervision of smart agriculture, as well as an example of its application in the beekeeping sector. It consists of the analysis of all the decisions that can be made using a spatio-temporal matrix that couples the time horizons to the modeling approaches. The final goal is to develop a reusable architecture for smart agriculture.
