These new simulators are expected to enable researches and developments focused on people reactions to simulated events via social networks. This research area results are promising, however, it is necessary to address also several challenging issues including proper development of new conceptual models as well as validation and verification processes and definition of human behaviour modifiers. The authors present a new methodological framework for modelling individuals and populations by means of web social networks, in order to reproduce their dynamics. The article proposes to create interoperable models of social networks along with a real case study related to training and decision making process for authorities. The paper includes experimentations over a complex scenario where human factors and social networks play a crucial role.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

This paper presents an agent-based approach enabling simulations to investigate manufacturing SMEs' immediate response to and short-term recovery from a flood event to evaluate the effectiveness of combinations of inundation precautions. Manufacturing SME agents exhibit pre- and post-flood behaviours gleaned from interviews with such businesses that have flood experience. Based on a flood event simulated for Sheffield in the UK, results show an individual SME with most precautions implemented in the lightly or moderately flooded area can return to 100% production approximately 7 days earlier than if the least precautions were employed. Further, considering the average short-term recovery of all SMEs with most precautions implemented in the lightly or moderately flooded area, 100% production can be achieved almost 20 days before manufacturers located in the severely flooded area.","PeriodicalId":266151,"journal":{"name":"Int.

The model was developed under Microsoft Excel™ and reproduces the main retail store processes (i.e., product receiving, backroom storage, sales area management and return management) in quantitative terms. As input, the model takes several data about these processes; as output, it provides an evaluation of the total cost and CO2 emissions of the store. The application of the model to a real case, referring to a large-scale retail store of Italy, and the discussion of the key results obtained is presented for all the processes considered. The outcomes show that the most relevant environmental impact and the highest total cost are generated by the sales area management process. Conversely, the return management process contributes to the total cost to a limited extent. A sensitivity analysis was carried out to highlight the key aspect managers should focus on to improve the sustainability of the retail store. The results obtained provide useful guidelines for store managers to optimise the sustainability of their internal processes.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

Also, they are unable to draw the pathways by which PRFs can affect workers' health leading to impaired job performance. The present study performs a comprehensive literature review on the psychosocial risk-related research and provides an evidence-based list for major PRFs. In addition, social network analysis (SNA) is implemented for developing the psychosocial risk network for further evaluation of the interactions between variables leading to the identification of key PRFs that play important roles in structuring the entire risk network. In the next step, a system dynamic (SD) model is developed to provide the mechanism underlying the development of musculoskeletal disorders and productivity loss due to exposure to psychosocial stressors.","PeriodicalId":266151,"journal":{"name":"Int.

Moreover, alternative instruments are presented and their specific advantages and disadvantages are described. Particularly, the paper proposes an innovative approach based on the SPIDER, an advanced interoperable interactive CAVE developed by the authors which supports cooperative work of several users involved in training, troubleshooting and supervision. Also, the use of such technology and approach in other fields is presented, such as the validation of training equipment for bus driving and related motion platform integrated in the SPIDER; in this case the solution is running a simulator, named 'BBBuS', used for training and RsD activities.","PeriodicalId":266151,"journal":{"name":"Int.

This study pushes for an increased attention on human factors, such as stress and perceived workload, in the occupational health and safety 4.0 and proposes an approach to analyse their effects with the ultimate aim to include them in the design of industrial safety protocols and regulations and in the assessment of hazards. The present paper answers the question whether and to what extent stress and the perceived workload are correlated to the capability of the emergency manager to coordinate and monitor the execution of all the actions intended to deal with an industrial accident and its effects. The findings of a cross-sectional regression of data collected from a series of training sessions carried out by means of virtual reality and serious games technologies show how a balanced workload and the ability to control emotivity are preconditions for mastering procedures and responding in the optimal way to an industrial emergency scenario.","PeriodicalId":266151,"journal":{"name":"Int.

Requirements represent the agreement, among the actors involved in the development process of a system (e.g., stakeholders, engineers), of what it is expected to be delivered. As they are neither computable nor verifiable, because typically expressed textually, their misunderstanding could lead to delay or even the failure of the overall system development. In this context, the exploitation of the properties modelling (PM) approach combined with the simulation is proposed to enable assessable requirements. In particular, PM is adopted for expressing requirements as computable and verifiable components, whereas simulation techniques are exploited for supporting their automatic verification and to evaluate their level of fulfilment. The simulation model along with the results gathered from the properties' evaluation represent the contract (design-by-contract) on which the actors can agree before the realisation of an actual CPS. The proposal is tested in the smart grid domain.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

Effective management of patient flows for 'ED' services has become a critical matter for most hospital supervisors. Many authors have tried to solve those issues based on different methodologies, with shared aims represented in the optimisation of patient care, by minimising patient waiting time at different levels in 'ED'. Modern studies mainly focus on limiting these issues by proposing a solution based on extending 'ED' resources. The case study was realised at the 'ED' of the hospital Chalabi Abdelkader, Mascara, Algeria. Then, the system was modelled by a coloured Petri net framework. Afterward, we performed simulations of numerous improvement scenarios. As a result, patient waiting times encountered in 'ED' were reduced, thus patient length of stay.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.
