Modeling and simulating play an important role in the industry, and even more in the innovative domain, for testing scenarios by anticipating different eventualities. Those simulations are often very complex and difficult to modify, that is why they could be built separately first and then run together. One of the most popular standards for distributed simulations is the IEEE 1516-2010-Evolved of the High Level Architecture (HLA) that supports implementation of distributed simulations. In our context, a company has launched a project of mobile factory to set up solar panel field in several countries. That implies various study domains and expertise (foundation definition, study of solar transmitters structure, risk analysis, project management, factory modeling). The goal of this paper is to demonstrate the interconnections proposed between all these entities. It will be implemented in the frame of a global simulation managed by HLA.
