Abstract
There is broad consensus that situation awareness (SA) plays a key role in agent-based modelling of complex sociotechnical systems. However in the social sciences and human factors literature there are different views on what SA is and how it could be modelled. More specifically, one school of research considers SA as the process of gaining awareness, another school refers to it as to the product of gaining awareness, whereas the third school sees SA as a combination of the process and product. Typically, agent-based modelling of SA is done from the second view for each individual agent, possibly with additional social components to enable interaction. Current developments in multiagent systems indicate that social abilities and relations between agents should be not an addition, but at the core of any model of a sociotechnical system. To address this issue, we develop a mathematical modelling framework of SA relations between agents which supports all three views. The use of the framework is demonstrated by an example of retrospective accident modelling from the aviation domain.
Highlights
Modern sociotechnical systems are characterised by high structural and behavioural complexities
In order to make progress in this challenging and divided domain of research, in this paper we develop a mathematical framework for modelling and analysis of multiagent situation awareness (SA) (MA-SA) which is based on MA-SA relations in a system of multiple agents
In order to capture this idea of unknown SA difference we introduce the concept of MA-SA consistency
Summary
Modern sociotechnical systems are characterised by high structural and behavioural complexities. Endsley and Jones [6] extend the original SA model of Endsley to shared SA and introduce differences in SA between multiple human agents in a sociotechnical environment. In order to make progress in this challenging and divided domain of research, in this paper we develop a mathematical framework for modelling and analysis of multiagent SA (MA-SA) which is based on MA-SA relations in a system of multiple agents. The MA-SA model in [13] extended the model of Endsley [3] by incorporating non-human agents, whereas the current paper uses the framework of Endsley and Jones [6] as a starting point to capture MA-SA relations and shared MA-SA between multiple human agents in a sociotechnical system.
