Kotov V.V., Zhestkova S.A. DETERMINATION OF RADIAL ROUTES FOR THE CARRIAGE OF GOODS BY ROAD TRANSPORTThis paper presents a solution to the routing problem of road transport on the basis of an improved algorithm of the method of fictitious nodes and branches, allowing us to obtain more accurate results. The task of routing offers the use of a technique of definition of optimal schemes of movement, which up to this time, exact solution of the problem in the General case is not found. One reason for this is the presence of various constraints when defining the objective function, taking into account the specifics of the type of transport. In particular in the delivery of petroleum products it is necessary to consider the following: the route is carried out on a specially designed circuit to account for the movement of dangerous goods, which does not always coincide with the shortest distance between points; for the transportation of petroleum products used heavy trucks. The result is that in many cases the free volume of the tanks at petrol stations (gas stations) are insufficient for the organization of the pendulum route. This work offers a way to improve the efficiency of delivery of goods, the method of fictitious nodes and branches when solving vehicle routing based on the input external redundant nodes, which allows more accurate to describe the process of cargo transportation. We propose an improved algorithm of the method of fictitious nodes and branches, containing 14 stages, allowing us to obtain exact solution of the problem vehicle routing to determine the radial routes. Provides a specific solution to a traffic problem on the basis of having a transport count on the proposed algorithm to determine the optimal radial routes for transportation of goods by road, based on the exact method of linear programming.Key words: dummy node, graph, matrix, method, algorithm.
