Brovarniy D.P.  A road work planning model based on neuron networks

Geographically distributed road faults and the facilities used for their maintenance are represented as a set of defects and a set of mechanisms for restoring road infrastructure. Each element from the set of defects has an associated loss cost, while each element from the set of repair mechanisms is related with the cost and efficiency relative to the subset of defects it can cover. An algorithm is developed enabling to determine the subset of elements from the set of repair mechanisms where the minimum of uncovered loss is attained at given repair mechanisms cost. The problem is solved using neuron network techniques.
Keywords: geoinformation systems, road infrastructure, road condition monitoring system, vulnerability of road network, road network restoration mechanism, efficient resource allocation.
