**2. IRRHEM Design and Development**

In this section, we present the design, the development, and the scenarios on the simulated environment of our IRRHEM proposed method. We begin with a presentation of the used method, followed by a study of the work environment. The results of this study will be used to develop the main elements of ontology (for instance, concepts, relations, and rules of reasoning). The following steps are reserved for editing the ontological data, testing, and validating the ontology. This section ends with the presentation of the scenarios of the simulation of the solution and the display of the results.
