APPLICATION OF LAGUERRE-VORONOI DIAGRAMS FOR CONSTRUCTION AND OPTIMIZATION OF THE EMERGENCY NOTIFICATION SYSTEM INFRASTRUCTURE FOR THE POPULATION

The relevance of the article is due to the need to develop and improve methods for optimal placement of sound signal sources of emergency alert systems to ensure the effectiveness of their functioning. The development of new approaches will reduce the costs of maintaining and placing such systems, improve their deployment time and provide the population of the alerting area with a normative and more comfortable level of acoustic pressure of sound signals.The purpose of the study is to develop an algorithm for using Laguerre-Voronоi diagrams to place sound signal sources of the emergency alert system, taking into account acoustic and other parameters that affect the quality of its operation.The article presents the results of modeling and an algorithm for using Laguerre- Voronоi diagrams to optimize the placement of sound signal sources in emergency alert systems. The proposed methodology allows you to model and determine coverage areas taking into account the effective range of alert sources, building density, terrain features and acoustic characteristics of the area. The developed algorithm takes into account the peculiarities of sound wave propagation in an environment with different conditions of acoustic wave absorption, taking into account the peculiarities of the territory's development and the height of the sources, which affect their effective range.The possibilities of applying the proposed approach are demonstrated in the example of calculating the locations of sound signal sources of the warning system for a model city area. The possibilities of taking into account the acoustic characteristics of buildings in the warning area and ensuring the parameters of the regulatory sound pressure level are shown. An algorithm for optimizing the use of the ranges of sound signal sources is presented.
