  • RED Reproductibilité - DAO et al - v finale.pdf.jpg
  • Article


  • Authors: Van Toan Dao , Vincent Breton, Hong Quang Nguyen, David R.C. Hill (2014)

  • Le calcul à haute performance prend une place croissante dans toutes les disciplines scientifiques. Dans ce contexte, la précision et surtout la reproductibilité des expériences numériques doit rester une préoccupation majeure. La recherche de reproductibilité, essentielle à toute expérimentation scientifique, est parfois négligée, notamment en simulation stochastique parallèle, avec à la clef des conséquences importantes sur la pertinence des résultats obtenus. Dans cet article, nous proposons une analyse des enjeux de la reproductibilité numérique. Nous identifions ensuite les principaux obstacles à sa mise en œuvre. Pour pallier à ces obstacles, nous proposons un ensemb...

  • Stochastic simulation is of key importance for scientific computing. Parallel stochastic simulations are becoming popular since the Monte Carlo method is easily parallelized. However, the main interests we observe in related publications deal with the following issues: simulation performance, applicability of the simulation, model design, etc. Even if these interests are justified, accuracy and reproducibility, especially for numerical simulation experiments, must remain a major concern in the process of increasing and diffusing scientific knowledge. We recently realized that this essential question of reproducibility is sometimes overlooked. In this paper we study the esse...

  • Modeling and Simulation of Fire Evacuation in Public Buildings.pdf.jpg
  • Article


  • Authors: Manh Hung Nguyen, Tuong Vinh Ho and Jean-Charles Richaud (2015)

  • The negative consequence of fire, especially fire in public buildings, brings too much of lost in both human and money. The fire evacuation specialists proposed many evacuate techniques, methods and policies adapting to the given building, groups of people, or situations. However, conducting experiments to test these proposed solutions, in the reality, is nearly impossible. Therefore, simulation of fire and fire evacuation to evaluate these proposals is a reasonable solution. This paper proposes an agent-based model for modeling and simulation of fire evacuation in public buildings. The model is implemented and tested using the GAMA agent-based simulation platform.

  • Modeling and simulation of the effects of landslide on circulation of transports on the mountain roads.pdf.jpg
  • Article


  • Authors: Hung Nguyen Manh, Ho Tuong Vinh, Nguyen Trong Khanh, Do Minh Duc (2015)

  • Landslides, as one of the major natural hazards, account each year for enormous property damage in terms of both direct and indirect costs. Mountain roads where probability of land sliding is the highest, causes hurdles not only in the traffic flow but generate various traffic problems in the form of congestion, high accidents rate and waste of time. This paper introduces an agent-based model for modeling and simulation of the effects of landslide on the circulation of transports on mountain roads. This model is applied to the National Road N°6 of Vietnam to visualize and analyze the effects of landslide on the road when it occurs. This model could help us to improve and op...

  • Impact of group on the evacuation process: theory and simulation.pdf.jpg
  • Other


  • Authors: XH Ta, D Longin, B Gaudou, TV Ho (2015)

  • Our main purpose is to build a simulation describing the persons movements in a public area during a crisis situa- tion. Our running example is about the evacuation process of a supermarket during a fire. The main difficulty of such works comes from the fact that it is generally impossible to obtain precise descriptions of persons behaviors. After several works on individual emotions we are convinced that emotion is well adapted to explain such actions in a situa- tion crisis. In the aim to test our hypothesis, we present here a first simulation (without any emotion management) that is a first step of our main purpose. This simulation aims to describe the well-known fact th...

  • Combining Process Simulation and Agent Organizational Structure Evaluation in Order to Analyze Disaster Response Plans.pdf.jpg
  • Article


  • Authors: Nguyen Tuan Thanh Le, Chihab Hanachi, Serge Stinckwich, Tuong Vinh Ho (2015)

  • This paper shows how to simulate and evaluate disaster re- sponse plans and in particular the process and the organization set up in such situations. We consider, as a case study, the tsunami resolution plan of Ho Chi Minh City, Vietnam. We firstly examine the process model corresponding to this plan by defining three scenarios and analyzing sim- ulations built on top of them. Then, we study the agent organizational structure involved in the plan by analyzing the role graph of actors and notably the power, coordination and control relations among them ac- cording to the Grossi framework. These evaluations provide recommen- dations to improve the response plan.

  • A Tool for Assessing Quality of Rescue Plans by Combining Visualizations of Different Business Process Perspectives.pdf.jpg
  • Book chapter


  • Authors: Alvaro Jose Peralta, Nguyen Tuan Thanh Le, Serge Stinckwich, Chihab Hanachi, Alexandre Bergel, Tuong Vinh Ho (2015)

  • Rescue plans for crisis situations such as natural or man- made disasters are mostly presented in a textual format by the relevant authority. Assessing the quality of a rescue plan requires analyzing differ- ent perspectives, such as plan complexity, resources costs, service time, allocation strategy and organization efficiency. Unfortunately, textual rescue plans lack a formal structure to ease the navigation through the document. To address this problem we are composing tailored visualiza- tions, each visualization represents a particular perspective. We provide a domain specific language to describe domain specific visualizations of processes. We validate our approach usin...

  • HoTuongVinh 1.pdf.jpg
  • Article


  • Authors: Nguyen Tuan Thanh Le, Chihab Hanachi, Serge Stinckwich, Tuong Vinh Ho (2015)

  • Coordination is one of the most important issues in order to reduce the damage caused by a crisis. To analyze the efficiency of a coordination plan, a BPMN (Business Process Modeling Notation version 2.0) model is usually used to capture the processes of activities and messages exchanged between the actors involved in a crisis, while an OCMAS (Organization Centered Multi-Agent System) model is used to represent the roles, their interactions and the organizational structures. In this paper, we describe a proposal that allows to perform an automatic transformation between BPMN and OCMAS models of the same coor- dination plan. The proposal is illustrated through a coordination plan of ...
