Vehicle Routing Problem (VRP) is one of the core issues of logistic distribution. But the traditional VRP doesn't consider the traffic condition of road network. Time Dependent Vehicle Routing Problem (TDVRP) is to study the problem of vehicle routing optimization in dynamic network with fluctuant link travel time. The traditional VRP has been proven to be an NP-hard problem, so it is more difficult...
It is necessary to decompose a large map into small pieces while performing vehicle navigation path analysis in an onboard device. A principal component analysis based network decomposition is constructed to solve this problem. An index of connectivity is proposed in this method, by which the most correlative vertices relative to the destination vertices can be extracted from the complete road network...
