Evacuation simulation through formal emotional agent based modelling

by Ilias Sakellariou Petros Kefalas - In Proceedings of the 6th International Conference on Agents and Artificial Intelligence (ICAART 2014 , 2014
"... Abstract: Evacuation Simulation is recognised as an important tool for assessing design choices for urban areas. Al-though a number of approaches have been introduced, it is widely acceptable that such simulation scenarios demand modelling of emotional aspects of evacuees, and how these affect their ..."

Formal Agent-Based Modelling and Simulation of Crowd Behaviour in Emergency Evacuation Plans

by Ioanna Stamatopoulou, Ilias Sakellariou, Petros Kefalas
"... Abstract—Crowd behaviour deviates from normal when an emergency evacuation is needed. Thus, simulation of evacuation situations has been identified as an important tool for assessing design choices of urban areas, such as buildings, stadiums, etc., and Agent Based Modelling has been employed to tack ..."

to tackle such problems. In this paper, we propose that formal modelling can rigorously define but also naturally lead to realistic simulations of such cases. Our main contribution is presenting how formal state-based methods, namely X-machines, can be employed to model agents in emergency evacuation plans

A formal approach to model emotional agents behaviour in disaster management situations

by Petros Kefalas, Ilias Sakellariou, Dionysios Basakos, Ioanna Stamatopoulou - In Proceedings of the 8th Hellenic Conference on Artificial Intelligence, SETN 2014 , 2014
"... Abstract. Emotions in Agent and Multi-Agent Systems change their behaviour to a more ’natural ’ way of performing tasks thus increasing believability. This has various implications on the overall performance of a system. In particular in situations where emotions play an important role, such as disa ..."

, such as disaster management, it is a challenge to infuse artificial emotions into agents, especially when a plethora of emotion theories are yet to be fully accepted. In this work, we develop a formal model for agents demonstrating emotional behaviour in emergency evacuation. We use state-based formal methods

An agent-based model for the interplay of information and emotion

by Mark Hoogendoorn, Jan Treur, C. Natalie Van Der Wal, Arlette Van Wissen - in social diffusion,” Proceedings of: Web Intelligence and Intelligent Agent Technology (WI-IAT , 2010
"... The spread of information and emotion within groups is studied in models of social diffusion. Evidence has been found that the emotional states of humans affect their information processing abilities, and hence, may affect the spread of information as well. This paper introduces an agent-based model ..."

A MULTI-AGENT MODEL FOR MUTUAL ABSORPTION OF EMOTIONS

by Tibor Bosse, Rob Duell, Zulfiqar A. Memon, Jan Treur, C. Natalie Van Der Wal
"... In recent times researchers have initiated investigating emotion as a collective property of groups, emphasizing the influence of combined emotions among group members on group processes. Within groups humans recognize and react emotionally to expressions of emotions of other group members. This pap ..."

. This paper uses a multi-agent-based approach to formalize and simulate such emotion contagion within groups. 1.

K.: Emotional decision making in large crowds

by Alexei Sharpanskykh, Kashif Zia - PAAMS. Volume 155 of Advances in Soft Computing , 2012
"... Abstract Currently it is widely recognised that emotions of people influence their decisions. In this paper the role of emotions in social decision making in large technically assisted crowds is investigated. For this a formal, computational model is proposed, which integrates existing neurological ..."

and cognitive theories of affective decision making. Based on this model several variants of a large scale crowd evacuation scenario were simulated. By analysis of the simulation results it was established that spread of emotions in a crowd increases resistance of agent groups to opinion changes and supports

Agent-Based Modelling of Emotion Contagion in Groups 1

by Tibor Bosse A, Rob Duell A, Zulfiqar A. Memon A, Jan Treur A
"... Abstract 1 To avoid the development of negative emotion in their teams, team leaders may benefit from being aware of the emotional dynamics of the team members. To this end, the use of intelligent computer systems that analyze emotional processes within teams is a promising direction. As a first ste ..."
Abstract - Add to MetaCart
step towards the development of such systems, this paper uses an agentbased approach to formalize and simulate emotion contagion processes within groups, which may involve absorption or amplification of emotions of others. The obtained computational model is analysed both by explorative simulation

ASC Model: a process model for the evaluation of simulated field exercises in the emergency domain

by Alayne Da , Costa Duarte , Marcos Roberto , Silva Borges , José Orlando Gomes , Paulo Victor Rodrigues De Carvalho
"... ABSTRACT The undefined flow of execution of activities in an evaluation process hampers its implementation. A consistent evaluation process defines interrelated methodological steps that make it easier for the evaluator to lead the process. This article presents a process model for the evaluation o ..."

of simulated field exercises in the emergency domain, including their sub processes and activities. The proposed model was derived from observations made during real situations of a simulated evacuation exercise of communities in high-risk areas in Rio de Janeiro (Brazil). The motivation came from the finding

A Computational Model based on Gross ’ Emotion Regulation Theory 1

by Tibor Bosse, Matthijs Pontier, Jan Treur
"... Emotion regulation describes how a subject can use certain strategies to affect emotion response levels. Usually, models for emotion regulation assume mechanisms based on feedback loops that indicate how to change certain aspects of behavior or cognitive functioning in order to get a more satisfacto ..."

This paper introduces an adaptive computational model for emotion regulation by formalizing the model informally described by Gross (1998). The model has been constructed using a high-level modeling

An Adaptive Agent Model for Affective Social Decision Making

by Alexei Sharpanskykh, Jan Treur
"... Abstract. Decision making under stressful circumstances may involve strong emotions and requires adequate prediction and valuation capabilities. In a social context contagion from others plays an important role as well. Moreover, agents adapt their decision making based on their experiences over tim ..."
