Model-based simulation and monitoring are becoming part of advanced learning environments. In this paper, we propose a model-based simulation and monitoring framework for management of learning assessment and we describe its architecture and main functionalities. The proposed framework allows user-friendly learning simulation with a strong support for collaboration and social interactions. Moreover,...
This paper presents OCCI simulation extension, a generic simulator for any kind of resources. To achieve that, we first study the position of cloud simulator entities against OCCI model. Afterward, we define an OCCI extension simulation. In order to study the usefulness of this extension, we implement in the second time a module for Eclipse IDE to define OCCI configuration graphically. This tool uses...
Due to a high penetration by renewables and a strong trend towards decentralization, future energy grids exhibit an increasingly emergent behavior. As a consequence new engineering approaches, based on decentralized decision making, have been proposed. The Agent.HyGrid project provides a framework for the design, development and testing of energy infrastructures. However, in contrast to other approaches...
Validation is an important topic on the life-cycle of software development, especially when we are working with crowd simulation. This is because when applied in safety fields, such simulation software must reproduce behaviors close to real life in order to obtain useful data. The International Maritime Organization of London (IMO) developed guidelines for validate evacuation systems. In this paper,...
The design of healthcare facilities involves the complex system in various spatial and temporal dimensions; it involves a wide range of functions, different kinds of users and activities, and various technical requirements. Understanding the complexity in healthcare facilities becomes important in order to ensure that the design could perform well to support healthcare services. This paper discusses...
Enhancing brand awareness through online social networks is increasingly pivotal to business success. This paper is concerned with a hybrid paradigm for modeling, simulation and analysis of brand virality in social media. In particular, mathematical models and graphical animation are proposed and formulated to represent the spread and viral process of a brand over social Web and mobile networks. Simulation...
In the context of the EU FP7 AMBASSADOR project, a simulation platform has been developed, as a support for the development and the deployment of energy management systems at the district level. Such simulation platform is called District Simulation Platform (DSP), and includes both the models of the physical components from the district, and the models of the energy management algorithms. The DSP...
El Yali National Reserve is a protected area that is priority number one for the National Forestry Corporation (CONAF). It is located in the V region of Chile, where the risk of wildfire is quite high. In this context, training actors involved in combating wildfire is a relevant issue. Under the simulation of serious video games, a simulator that allows this training was built, since it is not possible...
This paper presents a state of the art modeling techniques, namely the macroscopic model, mesoscopic and microscopic. And we will see that in order to solve problems related to space and time encountered in the above models, a new scale model called hybrid appeared Its purpose is to take advantage of conventional models, by adopting the model of the phenomenon. The simulation of multi-agent systems...
Today's Enterprises exist in highly dynamic environment. Simulation could be used to reveal complex dynamic behavior of enterprise, especially for playing out dynamic what-if scenarios, in determining enterprise's response to a change. Instead of relying on guidelines for simulating prescriptive models of enterprise as in other approaches including our own in which we simulated intentional models...
Today's Enterprises exist in highly dynamic environment. While enterprise-architecture (EA) based models help in holistic treatment of enterprise aspects, they are static in nature and do not represent the complex dynamic behavior of enterprise as it evolves over time. Instead of relying on guideline for simulating EA models as in other approaches, we propose a comprehensive metamodel of system dynamics...
This paper provides an overview of CyMRisk, an experimental architecture for computing mission risk due to cyber attack. In its current form, the approach employs a simulation of key aspects of a target business/mission process as well as attacker behavior to estimate mission impact due to cyber attacks. In addition, CyMRisk estimates worst case attacker level of effort associated with carrying out...
Task migration is the transfer of the execution of a process (task) from one processing element to another. It originates from the massive deployment of distributed systems in the parallel computing field to enable dynamic load distribution, fault resilience and to enhance data access locality. With the development of MultiProcessor System-on-Chip (MPSoC) architectures, the topic of task migration...
The validation of formal models is a challenge for formal methods. We propose JeB, a framework which generates and executes simulations of Event-B models, even highly non-deterministic ones. JeB allows users to safely insert pieces of code to supply deterministic computations where the automatic translation fails. We present how JeB translates Event-B model into JavaScript. We define Fidelity as the...
Decision making processes in some contexts, such as construction of infrastructures, require the design of prospective experiments. These experiments are designed to test hypothesis raised in the design phase. Following an adaptive methodology, these experiments will feed new iterations. In many cases, the development of these experiments is so costly that they must be performed using simulators....
Simulation of human activities in smart spaces is becoming a necessary toolset to enable telehealth research that promises smart, humanly scalable and cost-effective solutions for aging, disabilities and independence. Human activities are complicated and contain a large number of varieties. Most of the existing research on activity simulations has relied on sensor events processing. Even though event-driven...
This panel seeks to initiate a discussion within the modeling and simulation community about the way we teach conceptual modeling for simulation with the view of bringing about improvements. The challenge addressed is how to educate and equip the novice analyst to become a professional rather than letting him become an artist - being very much the current practice. The need for professionalism is...
Existing research on context and context awareness has broadly focused on the technical aspects of context acquisition and interpretation of users' surroundings, also called physical or sensor-based context. Such an approach is lack of reconciling the user's perception of real-world context and a context-aware system's interpretation of that context. Using Analytic Hierarchy Process (AHP), we propose...
Adversarial decision making is aimed at finding strategies for dealing with an adversary who observes our decisions and tries to learn our behaviour pattern. This contribution extends a simple mathematical model with strategies that vary along time, and motivates the use of heuristic search procedures to address the problem of finding good strategies within this new search space. The evaluation of...
In this paper we present an hybrid architecture for a computer supported collaborative work in pervasive computing environment simulator. This architecture supports pure simulation mode where all agents are simulated, real deployment where it seamlessly integrates pervasive computing to the computer supported collaborative work and finally an hybrid mode where real devices can interact with simulated...
