DETERMINATION OF THE OPTIMAL ROUTE FOR THE ELIMINATION OF THE ACCIDENT IN THE WATER TREATMENT FACILITIES OF ALMATY
Potentially dangerous objects of Almaty city are such objects in which concentration of energy or dangerous substances is concentrated, and accidents on them can be sources of emergencies, including chlorination station, chlorinator warehouse and chemical section of water supply system. Violation of the functioning of these facilities may adversely affect the economic and social aspects of the functioning of our city. In the event of accidents of different nature at technical facilities, in particular the head water treatment facilities, in conditions of acute time deficit, incomplete and inaccurate information, a huge role will be played by how quickly the emergency services of Almaty can react, make a decision and arrive as soon as possible to the treatment facilities to localize the accident. In this article, the problem of determining the optimal route for various emergency services located in different districts of Almaty is considered. A mathematical model with the use of linear and dynamic programming problems is presented and described for the solution. As the method of solving the problem, the algorithm for finding the shortest path in the graph, proposed by Bellman and Ford, is considered. Numerical examples are given. Also, for each district of the city, a road network has been constructed, an analysis has been made and optimal routes have been identified, which can be followed by various emergency services, such as: Fire Service 101, Police Service 102, Ambulance 103 and Rescue Service 112. In the research work, an enlarged structure of the information system for determining the optimal route for the liquidation of the accident at the water treatment facilities of Almaty city, consisting of seven stages, is proposed.
