“…Currently, either for "distance" or "face-to-face" education, the use of virtual laboratories (VL) experienced a great growth in various disciplines, namely the modeling and simulation of complex systems in physics [26][27], chemistry [11][28], biology [29] [30] [31] and even robotics and engineering [32] [33].…”

Abstract-The exponential growth of technology has contributed to the positive revolution of distance learning. Elearning is becoming increasingly used in the transfer of knowledge where instructors can model and script their courses in several formats such as files, videos and quizzes. In order to complete their courses, practical activities are very important. Several instructors have joined Multi-User Virtual World (MUVW) communities such as SecondeLife, as they offer a degree of interrelated realism and interaction between users. The modeling and scenarization of practical activities in the MUVWs remains a very difficult task considering the technologies used by these MUVWs and the necessary prerequisites. In this paper, we propose a framework for the OpenSimulator MUVWs that can simplify the scenarization of practical activities using the OpenSpace3D software and without requiring designers to have expertise in programming or coding.

“…In DEVS, a model is represented by a 7-tuple (I, O, S, δ ext , δ int , λ, t a ), where I and O represent the inputs and outputs of the model, S is the vector of state variables, t a represents time advancement in simulation, δ int is the evolution of internal states of model while δ ext represent the influence of external events to model's internal states. Model coupling in DEVS consists of encapsulating the individual models into a big global DEVS multi-model [58][59][60].…”

On Conceptual Structuration and Coupling Methods of Co-Simulation Frameworks in Cyber-Physical Energy System Validation

Co-simulation is an emerging method for cyber-physical energy system (CPES) assessment and validation. Combining simulators of different domains into a joint experiment, co-simulation provides a holistic framework to consider the whole CPES at system level. In this paper, we present a systematic structuration of co-simulation based on a conceptual point of view. A co-simulation framework is then considered in its conceptual, semantic, syntactic, dynamic and technical layers. Coupling methods are investigated and classified according to these layers. This paper would serve as a solid theoretical base for specification of future applications of co-simulation and selection of coupling methods in CPES assessment and validation.

“…It is based mainly on virtual laboratory environment (VLE), which is a free and opensource software developed in C++ that provides a simulation engine, modeling tools, software libraries, and an integrated development environment (Quesnel et al 2009). It is a generic modeling, simulation, and analysis environment based on the discrete event system specification (DEVS) formalism that originated from the theory of Modeling and Simulation defined by Zeigler et al (2000).…”

Developing sustainable crop systems is a major challenge. Presently, management practices are simulated using either biophysical models or simple farmer decision models. As a result, there is a lack of generic models integrating both biophysical parameters and farmer decision parameters. Here, we developed an original graphical plug-in to sketch and implement decision-making models and to link them with biophysical models. For that, we used the RECORD platform, standing for REnovation and COORDination of agro-ecosystem modeling. Different pop-up windows allow to create the model using a decision formalism then to implement the model under the RECORD platform. The sequence of technical operations is formally modeled as a direct multi-graph without retroaction. The plug-in allows defining activities, relation between activities, and decision rules to trigger the different activities. The resulting model is independent of any biophysical model and can then be linked with different crop models. An example is given on an innovative cropping systems part of the MicMac-Design project. The decision-making model is then linked with the STICS crop model.
