A Fading Memory Model for Indoor Evacuation - Preliminary Results

Abstract

Observations of a process in an environment happen over time and their validity can be ephemeral. Thus, knowledge of the environment may quickly become out of date, which matters especially in safety-critical applications. For example, emergency situations happen after sudden changes to the environment and are continuing to change the environment, while people are trying to evacuate based on their outdated spatial knowledge. This means, the value of time-stamped spatial knowledge fades over time. While historical spatial knowledge can be an accurate mapping of the historical environment, the validity of this knowledge in a changed or changing environment should be considered when used for de..
