Document to model transition for architecture evaluation approach: Application to a nuclear infrastructure project.

In large engineering projects, multiplicity and heterogeneity of business actors, domain and business constraints, and stakeholders’ needs become more and more difficult to manage and are even moving. To allow projects members to converge in confidence, reducing time, costs and avoiding risky situations due to errors, misinterpretations, or omission, Model Based System Engineering (MBSE) replaces today the classical documents centric engineering approach. It promotes modeling, models and data management principles that are largely used in several domains with success. This article focuses on Nuclear Infrastructure engineering projects. It intends to demonstrate the interest of deploying MBSE approach in this field, particularly concerning architectural solutions evaluation. Main principles and application results of an MBSE driven method called EVA-CIME are proposed, presenting some gains and perspectives.
