Aiming at the problem that the consistency between load capacity and the actual traffic volume, the road grade analysis in urban traffic network. Propose the improved GROCC algorithm based on the traditional Dijkstra algorithm. It is a global path planning method based on real-time traffic information. In this algorithm, the parameter, the number of recommended times are used as an important factor...
To estimate the contribution of main vibration and noise sources of vehicles, a source contribution estimation method based on an improved independent component analysis (ICA) algorithm is proposed. A measure of the similarity between the independent components and the reference signals with given characteristics is introduced. A widely used contrast function, namely kurtosis, is enhanced by the measure...
Considering that travel routing costs change with time against the background of reverse logistics, this paper presents the time dependent vehicle routing problem of simultaneous delivery and pick-up (TD-VRPSDP), and establishes the mixed integer programming model of TD-VRPSDP. The pheromone updating strategy based on rank-based ant colony system and max-min ant system algorithm are used for solving...
