AIC approach for intelligent systems requirements elicitation

This paper introduces an AIC (Appreciation, Influence, and Control) based method for requirements elicitation, which describes and evaluates complex problems involving intelligent systems. Our approach integrates Critical Systems Engineering and AIC Soft Systems Design Theory for eliciting a comprehensive set of Intelligent Systems Requirements. It focuses on enhancing the architect's ability to appreciate and understand intricate intelligent behaviours in complex problems to predict emergence. Our proposed architecting strategy suggests a modelling method by transitioning from a macroscopic (holistic) view of a problem to a microscopic specification (reductionist view) of intelligent system actions in a systematic, hierarchical, incremental fashion. We consider the problem as a system of systems (soft and hard systems) to better encompass the extent of the design space and anticipate the nuances of increasing complexity after deploying an intelligent system over time. This paper bases its architecting philosophy on the AIC soft systems design theory, an incremental abstract-based system requirements derivation approach SHARCS (for hard systems design) and the HAZOP framework. The output of this process is a comprehensive set of hazardous and opportunistic scenarios and intelligent systems' behavioural requirements in those scenarios.

Additional Information: Funding Information: In the future, we will be applying the process to a different case study and perform a comparison with other techniques (such as SHARCS, STPA [12], SEC-STPA [14], and Krishnan [15]) to understand further the AIC approach impact on producing rich safety concept. Additionally, we will advocate for the integration of icons in AIC models. Using pictography can mitigate potential misunderstandings, especially when dealing with complex models. The inclusion of icons in systems modelling has gained significant attention recently due to its potential to enhance clarity and comprehension across cultures and engineering mindsets ACKNOWLEDGEMENT Al-Shareefy is supported by a Thales EPSRC iCASE Award.
