Implementation of Human System Integration (HSI) and ‘Non-functional Characteristics’ into the Systems Engineering Lifecycle - A Practical Approach at Airbus Defence and Space

Abstract

This paper provides an overview of the process, practices, developments and synergies that Airbus Defence and Space are implementing Human System Integration (HSI) into the Continuous Engineering /Model Based System Engineering (MBSE) throughout the company. The paper highlights these developments, which include internal research programmes, European Union funded research projects, Airbus internal Synergy project. This research includes an EU funded 3 year project HoliDes - Holistic Human Factors and System Design of Adaptive Cooperative Human Machine Systems. Continuous engineering within Airbus has included various corporate and divisional Synergy programs and lean and agile initiatives. As our business is defined by Multiple Portfolio products, supplied from multi countries, the MBSE process had to speed up delivery and reduce overall cost. The Airbus process models needed significant amendment due to products supplied via multiple business lines throughout the company. This problem is exacerbated by varying requirements of four national defence requirements, who impose restrictions on the use of Architectural Frameworks (NAF/MODAF/DODAF) and supporting tools. Our Human System Integration (HSI) is continuing from the initial Human View Architectural Framework research to include the nine HSI domains. These nine domains overlap with our current Human factors research and will now allow us to pull in our Non-functional work into our Systems Engineering lifecycle. This paper highlights the research projects Airbus Space and Defence are incorporating in to our overall strategy, these include internal R&D funding and European Union funded research programs. These research projects have highlighted several areas of interest these include, stochastic modelling with respect to Human System Integration and Human views, verification and analysis of emergent behaviour and non-functional properties, which conforms with our own work on non-functional requirements and finally the use of System of System Formal Methods for parts of the lifecycle.
