- W77265939 abstract "Efficiently managing and organizing crowds in emergency situations has become a more important area of study in the last years and plays an important role in the design of a building or area. The use of simulation techniques to predict these situations is becoming more common as it aims to predict and prevent major accidents. Unfortunately, studies that focus on the safety of a project take place after the project is designed. Performing these studies at this phase increase the project’s cost and its duration, so it becomes important to study a solution that allows designers to verify the safety of the building as well the efficiency of its evacuation routes. There are several simulation techniques from which we can highlight different approaches based on particle systems and heterogeneous multi-agent systems. There is also a range of existing simulators with different purposes. Considering a BDI agent architecture, there are also several approaches when it comes to the definition of the agents and their beliefs desires and intentions. The problem on which this dissertation focus is the implementation of a module on a previously developed simulator that allows designers to create and configure agent types in order to create more realistic simulations, therefore improving their outcome. The simulator used as a starting point for the implementation of this module is the ModP simulator. This simulator has all the needed features to implement the desired module and uses Qt for interface and the OpenSteer library for movement and steering behaviour. The implemented agent editor module allows the creation of agent types trough a simple syntax that specifies the agents parameters, such as maximum speed and vision range, and its evacuation plan. This plan consists in a group of pre-implemented commands that specify which action should be taken by the agent and in which order. While modeling the simulation it is possible to select the types of agents that will be present in it and their distribution in percentage. A batch of tests were made in order to show the realism improvement brought by the implementation of this module. It is possible to observe how changing parameters and agent types interferes with the crowd behaviour, speed and evacuation time. In conclusion, the implemented module allows an easier and more realistic specification of the agents in the simulation, resulting in a more realistic simulation. Some interesting features were not implemented but would increase even more the realism of the simulator and better aid designers to assess the project’s safety." @default.
