This paper provides an ontological perspective that aims to boost the quality management and the contribution of the various economic spheres comprising a port-valley system. The proposed conceptual approaches will help clarify the complex interactions between macroeconomic circumstances and microeconomic strategies characterizing a geo-economic system. To this end and based on the observation of a lack of "reference and easily usable" databases, we seek to provide policy makers with a technical geomatic and statistical tool for tracking the performance of the various territories of any port-valley. As well, through the creation of the GeoEcoStat Database, we want to enable efficient comparisons between these territories.

Keywords: Port-valley system, aggregate planning, decision making process, multi-agent systems, adaptive systems, GeoEcoStat database.
