The design of an agent based model of human activities and communications in cardiac resuscitation

2015

International audience; Cardio-pulmonary arrest is a common emergency situation causing over 400,000 deaths per year, more than a 1000 per day, in the USA alone. The goal of this work is to develop an agent based computer simulator that will allow trainers to experiment with different communication protocols, such as those found in air traffic control. This paper describes the first step in designing the simulator development. The design is based on an analysis of communications during real life training simulations using the FIPA standard categories.

Towards an Agent-Based Model for the Analysis of Macroeconomic Signals

2020

This work introduces an agent-based model for the analysis of macroeconomic signals. The Bottom-up Adaptive Model (BAM) deploys a closed Walrasian economy where three types of agents (households, firms and banks) interact in three markets (goods, labor and credit) producing some signals of interest, e.g., unemployment rate, GDP, inflation, wealth distribution, etc. Agents are bounded rational, i.e., their behavior is defined in terms of simple rules finitely searching for the best salary, the best price, and the lowest interest rate in the corresponding markets, under incomplete information. The markets define fixed protocols of interaction adopted by the agents. The observed signals are em…

Do editors have a silver bullet? an agent-based model of peer review

2014

This paper presents an agent-based model of peer review that looks at the effect of different editorial policies of referee selection. We tested four author/referee matching scenarios as follows: random selection of referees, selection of referees with a similar status to submission authors, selection of higher-skilled and lower skilled referees. We tested these scenarios against three types of referee behaviour, i.e., fair, unreliable and strategic and measured their implications for the quality and efficiency of the process. Results show that in case of randomness of referee judgment, any editorial policy is detrimental for peer review. If referees behave strategically, certain matching p…

Modeling and Simulation as a Pedagogical and Heuristic Tool for Developing Theories in Cognitive Science: An Example from Ritual Competence Theory

2019

An interdisciplinary team of researchers in the fields of philosophy, religious studies, cognitive science, and computer science aimed to develop a computer model of ritual behaviour, based on McCauley and Lawson’s theory of ritual competence. That endeavour revealed some questions about the internal consistency and significance of the theory that had not previously been noticed or addressed. It also demonstrated how modeling and simulation can serve as valuable pedagogical and heuristic tools for better specifying theories that deal with complex social phenomena.

A Full-Scale Agent-Based Model to Hypothetically Explore the Impact of Lockdown, Social Distancing, and Vaccination During the COVID-19 Pandemic in L…

2021

Background The COVID-19 outbreak, an event of global concern, has provided scientists the opportunity to use mathematical modeling to run simulations and test theories about the pandemic. Objective The aim of this study was to propose a full-scale individual-based model of the COVID-19 outbreak in Lombardy, Italy, to test various scenarios pertaining to the pandemic and achieve novel performance metrics. Methods The model was designed to simulate all 10 million inhabitants of Lombardy person by person via a simple agent-based approach using a commercial computer. In order to obtain performance data, a collision detection model was developed to enable cluster nodes in small cells that can b…

Agent-Based Model to Study and Quantify the Evolution Dynamics of Android Malware Infection

2014

[EN] In the last years the number of malware Apps that the users download to their devices has risen. In this paper, we propose an agentbased model to quantify the Android malware infection evolution, modeling the behavior of the users and the different markets where the users may download Apps. The model predicts the number of infected smartphones depending on the type of malware. Additionally, we will estimate the cost that the users should afford when the malware is in their devices. We will be able to analyze which part is more critical: the users, giving indiscriminate permissions to the Apps or not protecting their devices with antivirus software, or the Android platform, due to the v…

A Theoretical Agent-Based Model to simulate an Artificial Social Evolution

2013

Agent-based social simulation as a computational approach to social simulation has been largely used to explore social phenomena. The purpose of this paper is to build a theoretical agent-based model to simulate the social evolution of a set of agents/artificial societies. In this model, each agent (artificial society) has an available number of social behaviours that compete among each other. The agent/agent interactions are carried out by their social otherwise, the agent/environment interactions are expressed through the consumption of ecological resources in repression and satisfaction by social behaviours of the agent. In this work, we will present the structure and the formulation of …

ABM of Civil Violence: ODD Description

2017

This chapter contains a description of the proposed agent-based model, using the well-known “Overview, Design Concepts and Details” protocol. The model was implemented in NetLogo and is based on the same two types of agents—citizens and law-enforcement—as in Epstein’s model, but “citizen” agents have one subtype (“activist”) used for implementing network influence effects. The salient aspects of the model description are centered on the submodels for the risk perception, the expression of hardship in terms of value-sensitive relative deprivation, endogenous legitimacy feedback and network influence effects, which provide extensions to Epstein’s model. The model includes two networks called …

When Competition Is Pushed Too Hard. An Agent-Based Model Of Strategic Behaviour Of Referees In Peer Review

2013

This paper examines the impact of strategic behaviour of referees on the quality and efficiency of peer review. We modelled peer review as a process based on knowledge asymmetry and subject to evaluation bias. We built two simulation scenarios to investigate largescale implications of referee behaviour and judgment bias. The first one was inspired by “the luck of the reviewer draw” idea. In this case, we assumed that referees randomly fell into Type I and Type II errors, i.e., recommending submissions of low quality to be published or recommending against the publishing of submissions which should have been published. In the second scenario, we assumed that certain referees tried intentiona…
