Model-based system engineering is increasingly being used in system design and development, but rarely in later project phase activities such as assembly, integration and testing/verification and validation (AIT/AIV).

This paper by RHEA Group’s Pablo Beltrami and Nieves Salor Moral looks at the production of a tool suitable for the reporting of AIT and AIV activities, taking into consideration two important questions. How will all parties share the same understanding? And how can the documentation of such understanding be automated?

Abstract introduction

The application of model-based system engineering (MBSE) to manage the growing complexity in system design and development starts at the beginning of a project on the left side of the systems engineering V-model by conducting analysis of the problem and the potential concepts on functional and logical level, all the way down to specifying the concrete technical solution on physical level. However, little application is currently seen in the space industry to apply MBSE as support for the activities on the right side of the V-model, i.e. for assembly, integration and testing/verification and validation.

The objective of the Model-Based System Engineering for AIV (MBSE 4 AIV) system, the subject of this paper, is to bring the same principles and related benefits to these later project phase activities by creating a single source of truth for AIV relevant information capture and exchange between different tools for on/off-site AIT test campaigns to avoid manual work and inconsistencies.

The production of a tool suitable for the reporting of AIT and verification activities using a language understood by all parties is thus the final goal of the project.
