Beskrivelse af forslaget:This International standard describes a protocol for the verification and validation of building fire evacuation models. The present document mostly addresses evacuation model components as they are in microscopic agent-based models. Nevertheless, the user of this protocol may adopt it (entirely or part of it) for macroscopic models if the model is able to represent the components under consideration. The area of application of the evacuation models discussed in this document includes performancebased design of buildings and the review of the effectiveness of evacuation planning and procedures. The evacuation process is represented with evacuation models in which people movement and their interaction with the environment make use of human behaviour in fire theories and empirical observations. The simulation of evacuation is represented using mathematical models and/or agent-to-agent and agent-to-environment rules. The area of application of this standard relates to buildings. This document is not intended to cover aspects of transportation systems in motion (e.g. trains, ships) since specific ad-hoc additional tests may be required for addressing the simulation of human behaviour during the evacuation in these types of systems (Guillaume and Thiry-Muller, 2018). This document includes a list of components for the verification and validation testing as well as a methodology for the analysis and assessment of accuracy associated with evacuation models. The procedure for the analysis of acceptance criteria is also included. A comprehensive list of components for testing is presented in this document since the scope of the testing has not been artificially restricted to a set of straightforward basic set of applications. Nevertheless, the application of evacuation models as a design tool may be affected by the numbers of variables affecting human behaviour under consideration. A high number of influences might hamper the acceptance of the results obtained given the level of complexity associated with the results. Simpler calculation methods such as macroscopic models, capacity analyses or flow calculations are affected to a lower extent by the need to aim at high fidelity modelling. In contrast, more sophisticated calculation methods (i.e. agent-based models) rely more on the ability to demonstrate that the simulation is able to represent different emergent behaviours. For this reason, the components for testing are divided into different categories so that the evacuation model tester can test an evacuation model both in relation to the degree of sophistication embedded in the model as well as the specific scope of the model application.
