Aiming at the path planning problem of AGV in the material handling system of manufacturing workshop,an AGV path planning method considering blocking was proposed.The congestion coefficient of the path was calculated based on the statistics of the AGV transport in the path between adjacent nodes.The statistical handling time matrix of the AGV was calculated according to the congestion coefficients,which was used as the weight matrix of path planning.Dijkstra algorithm was designed to get the shortest statistical handling time path from the given starting point to the end point,and it was stored in the shortest statistical handling time path table for query.The case study results show that compared with the traditional Dijkstra algorithm,the AGV path planning method considering blocking can effectively reduce the handling time and improve the handling efficiency.
