THE VEHICLE ROUTING PROBLEM WITHIN THE INFORMATION SYSTEM FOR CITY ROAD MAINTENANCE PLANNING

The work is devoted to information system for city road maintenance planning. The main component of this system is the vehicle routing problem while servicing the city's transportation network when performing such operations as clearing roads from rubbish, dirt and dust, creating road markings, clearing snow and spreading anti-icing materials. Mathematically, the problem is reduced to a Min-Max Capacitated k-Chinese Postman Problem with Deadline Classes. An additional feature of the considered problem is the consideration of traffic intensity on the roads. The modification of the general algorithm for solving the problem takes into account the characteristic properties of the model. Considered the components of the developed information system for city road maintenance planning which can be used in the future by municipal services when planning routes during performance of certain types of road works.
