Although new learning methods, such as virtual reality (VR), have been deployed, they still do not find implementation on a large-scale. This research proposes the concept of 'virtual training pills' (VTP), i.e. delivering learning content in the form of short educational games by using a common technological platform based on virtual, interactive and immersive reality. An application study has been conducted in the case of a decommissioned nuclear power plant, which is classified as confined and pollution-suspected space. These areas represent a challenging environment for maintenance and inspection activities. The results proved the potential of this novel game-based learning approach: short 'learning pills' are much more effective than long role-playing games. This work also discusses the benefits of workforce training based on VTP as an integration to live exercises for safety management.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

In this paper, we present a novel approach to modelling and simulation of discrete event dynamic systems (DEDS), based on the combination of discrete event systems specification (DEVS) and agent group role (AGR). In this study, the DEVS atomic models are transformed into agents and the DEVS coupled models into groups of agents. Thus, we provide a set of procedures and functions that allow the systematic transformation from DEVS into AGR models in order to be implemented in multi-agent platforms. The proposed approach was validated by a case study, an application in the water supply used in natural gas liquefaction process.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

This paper focuses on the miniaturised structure design process and the corresponding modelling and simulation. Two types of electromagnetic AEMs with oscillating coil actuator or solenoid actuator were compared in space occupation, sealing performance, cost, static load capacity and dynamic performance, and their advantages and disadvantages were summarised, then the optimal design of the miniaturised structure was carried out using the finite element model (FEM) and lumped parameter model (LPM) and simulations. The final design of the miniaturised AEM had small dimensions and similar performance to those ordinary AEMs. The miniaturised design and simulation process shown in this article can improve the space utilisation of AEM while ensuring no performance degradation.","PeriodicalId":266151,"journal":{"name":"Int.

It plays an important role for the thermal comfort of the residents and the energy consumption of the building. The objective of this work is to analyse the thermal behaviour of the building structure in humid climates for various local building materials: wood, cinder block and clay brick. To achieve this, a numerical code was written in the MATLAB 2014a software to solve by the finite difference method implicit scheme, the three-dimensional heat transfer equation. The simulation of our dynamic model takes into account the convection on the external and internal surfaces as well as the diffusion in the material constituting the structure. The particularity of this study is that in addition to being a 3D model, it allows to appreciate the behaviour in the thermal bridges and in the interior geometric centre. After analysis, we recommended an envelope made of wood material in the littoral region.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

The generated vibration shortens the life of the ring die and also decreases its reliability and stability. According to the principle of biomass pelletisation, a new model of cyclic extrusion force calculation was established, in this paper, by considering the changes in distance between ring die and roller against time. A dynamic simulation model of a ring die pellet mill with eccentricity was developed in LS-DYNA software, and the internal stress distribution of biomass was calculated. The obtained results revealed that the internal stress on biomass and the angle of extrusion both gradually decreased with the increasing distance between ring die and roller. The relationship between distance and extrusion force was linear when the distance was in the range of 0.5-1.5 mm. Extrusion force manifested a periodic variation, and its frequency was consistent with the rotational frequency of the ring die. The vibration amplitude of extrusion force was related to the eccentricity of the ring die.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

Based on the bat algorithm (BA), a self-adaptive elite bat algorithm (SEBA) is developed as the global optimisation method in this study by using Hamming distance-based elite individual set and adaptive position update. Crossover tests are designed to determine the optimal values of critical parameters in SEBA.

When patients are obliged to stay in a department until a bed becomes available in the next department, 'bed-blocking' occurs. Hospitals often suffer from the lack of proper planning and ineffective management of hospital beds and medical resources. In this research, we tackle this issue by introducing a multi-objective simulation optimisation model to determine the optimal number of elective admissions, the appropriate number of beds, and the number of patients who are forced to discharge in each ward. The model minimises hospital costs and the number of patients who are blocked. Due to the complexity of the issue, two meta-heuristic approaches are developed to solve the model. In this regard, five simulation optimisation algorithms have been implemented to solve the model and compare the results. By solving the presented algorithms, Pareto optimal frontiers are obtained in various states.","PeriodicalId":266151,"journal":{"name":"Int. J. Simul. Process.

Based on the related research, this paper designs a co-evolution mechanism for the parameters of PSO including both the inertia weight and the acceleration factors, which defines stochastic evolution speed to reflect the current state of population evolution during the iterative process, and uses it as the feedback to set the inertia weight and the two acceleration factors. PSO with the parameter co-evolution mechanism can realise cooperative evolution of the running parameters with the population by dynamically adjusting parameter values according to population evolution state. Compared with five widely recognised parameter selection or adjustment strategies, on 20 numerical optimisation benchmark functions of different categories, the effectiveness and the efficiency of the proposed mechanism are verified.","PeriodicalId":266151,"journal":{"name":"Int.

To this end, a traffic simulation model was developed to estimate improvements in several traffic and environmental performance measures. A total of 11 traffic scenarios were simulated and their results were compared. These scenarios varied from a baseline situation, i.e., the current AM peak-hour traffic, to a variety of traffic-reduction scenarios ranging from 5% to 50% with an increment of 5%. The results showed considerable improvements in traffic flow and air-pollution performance measures. All performance measures witnessed steady improvement as more traffic reduction occurred; nevertheless, traffic measures have seen more improvement as opposed to environmental measures. Statistical significance tests showed that 5% traffic reductions did not show significant impacts on performance, 10% reductions will improve traffic flow, whereas 20% traffic reductions will improve both traffic and air emissions.","PeriodicalId":266151,"journal":{"name":"Int.

In order to stabilise the production of the oilfield, it is an effective measure to develop the oilfield by water injection. Therefore, it is very important to study the pressure regulating water injection technology, and the hydraulic automatic regulating device is the key. In this paper, a set of hydraulic automatic pressure regulating water injection devices is developed, which mainly includes three parts: screw motor module, screw pump module, and transmission device between screw motor output shaft and screw pump input shaft. The shunt injection of each layer can be realised without deployment by the automatic pressure regulating device. The change of total water injection volume can automatically adapt to the reservoirs according to the flow distribution ratio. At the same time, the test and field experiment in Shengli Oilfield, Dongying, China, show that the developed device has good energy saving effects.","PeriodicalId":266151,"journal":{"name":"Int. J.
