We assume uncertain scenarios with limited testing capacity, lack of reliable data, under-reporting of cases, and restricted testing policy. A Bayesian framework is proposed for the identification of model parameters and uncertainty quantification of the model outcomes. We identify through sensitivity analysis (SA) that the model parameter related to social distancing measures is one of the most influential. Different relaxation strategies of social distancing measures are then investigated to determine which are viable and less hazardous to the population. The scenario of abrupt social distancing relaxation implemented after the peak of positively diagnosed cases can prolong the epidemic. A more severe scenario occurs if a social distancing relaxation policy is implemented prior to the evidence of epidemiological control, indicating the importance of the appropriate choice of when to start the relaxation.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"17 1","pages":"178 - 192"},"PeriodicalIF":2.5,"publicationDate":"2021-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43816092","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is necessary that agents are aware of their society and still understand their context of action and interaction. Such social situation with other agents is influenced by society’s characteristics, including their norms, values, common interests and objectives, members, and social structures. Each complex society is broken down into social groups, each one with an identity. Social identity theory is seen as an analysis of intergroup relations in social categories based on the cognitive definition and the autoconcept of a social group and their belonging. Researchers have been studying this theory in computing, more specifically in multiagent systems. Social exchanges are the object of study in diverse contexts in which social relations are understood as social exchanges. One of the investigated themes is the self-regulation of social exchanges. The game of self-regulation of social exchanges explores its self-regulation but it does not analyse the agents’ identity. Therefore, this research investigates the integration of psychosocial analysis of social identity theory into the social adaptive complex society of the game of self-regulation of social exchanges. The principal result of this work is the GSRSEPSIT, a social simulation model.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"17 1","pages":"164 - 177"},"PeriodicalIF":2.5,"publicationDate":"2021-09-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44102202","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is continued development of second-generation biofuels (SGB), crops founded upon low-value feedstocks thriving on marginal (low quality) land. SGB’s alter the farming decision environment since they do not compete directly with high-value annual crops. To examine possible future consequences of SGB’s on mixed farming, we develop anagent-based simulation model (ABM) of a major agricultural region in Western Canada. If energy prices for SGB’s rise high enough, there will likely be structural changes in the sector. Farmers with significant quantities of marginal land experience the greatest benefit adopting energy crops. Spillover effects of energy crop adoption will also be felt in the beef industry since cattle numbers will be gradually reduced. Simulation results also indicate that beef farmers are better off with SGB crops since energy crops stabilise farm income as average farm size decreases.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"17 1","pages":"149 - 163"},"PeriodicalIF":2.5,"publicationDate":"2021-09-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47178798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This research aims to investigate the contribution of Italian citizens’ trust in Public Institutions and how it influenced the acceptance of the necessary counter measures. Applying linear regression to a dataset of 4260 Italian respondents, we modelled trust from its main cognitive components, with particular reference to competence and willingness. Therefore, exploiting agent-based modelling, we investigated how these components affected trust and how trust evolution influences the acceptance of these restrictive measures. Our analysis confirms the key role of competence and willingness as cognitive components of trust. Results also suggest that a generic attempt to raise the average trust, besides being challenging, may not be the best strategy to increase compliance. Furthermore, reasoning at category level is a fundamental to identify the best components on which to invest.","PeriodicalId":51296,"journal":{"name":"Journal of Simulation","volume":"17 1","pages":"105 - 119"},"PeriodicalIF":2.5,"publicationDate":"2021-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42149011","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clients access services via nearby Fogs, which then discover the required resources to run experiments (on Fogs or cloud backbone). Our focus is on mobility, to permit clients to conduct experiments (and visualise simulation results) using mobile devices. Mobility support is further improved by introducing the novel concept of a mobile simulation experiment: if a device moves away from a given Fog zone, the experiment moves with the device.

Therefore, evaluation of long-term adequacy of specific decisions regarding the OR planning is of a notable importance. Since hospitals deal with a varying environment, every long-term analysis must investigate the hospital responsiveness to the relevant changes. For this purpose, the system dynamics (SD) approach can be very useful. Generally, SD models are not dependent on high-quality and can be applied to problems at strategic levels. Using a SD approach, this paper aims to consider OR departments as multi-product systems and study their dynamism. The proposed model is based on a mesoscopic approach, which represents the flow processes through piecewise constant rates. The proposed model is generic, modular and easy to extend and described by means of MATLAB/Simulink®.

Moreover, one of the significant long-term challenges is sustainability performance across its entire supply chain. However, this is not an easy task given the complexity involved, so decision support tools are fundamental instruments in understanding the entire supply chain from a sustainability performance perspective. Using simulation as a research method, this article proposes a hybrid and hierarchical performance assessment model, considering key sustainability indicators. The model is hybrid due to the use of different simulation methods– System Dynamics (SD), Discrete Event Simulation (DES), and Agent-based simulation (ABS). The model is applied to an aerospace manufacturer’s real case to assess the sustainability performance of alternative SC.
