Abstract

A sufficient number of public notification systems in the case of emergencies at nuclear power plants have been developed and implemented. However, most of them have some drawbacks related to system performance, the ability to direct the public to evacuation points, promptness in warning. Mostly, they do not use the capabilities of state- of-the-art technologies — mobile applications for smartphones, which allow elimination of these drawbacks. This research is aimed at the design and development of the public notification system using an algorithm for making effective plans of evacuation in emergencies based on the client- server architecture. In addition to the server and client parts, the package also uses Google Maps services for dealing with an interactive map. A special characteristic of this software solution is an innovative approach to the calculation and transfer of the evacuation plan to the victim. The following three parameters are the most important in finding an effective way for each victim: distance to the shelter; time to cover an estimated distance; movement speed. Such an algorithm makes it possible to calculate an adequate route of evacuation separately for each victim, adjusting the distance depending on the speed of movement and fullness of shelters. The efficiency of the developed algorithm for the distribution of potential victims in shelters and evacuation points is presented in AnyLogic models. The paper presents the analysis of using the evacuation model for short path and using the developed path calculation algorithm. The simulated situations have shown the possibility of saving a larger number of people. The developed information system effectively deals with the models built in the AnyLogic program.
