Material delivery distribution method and device

The invention discloses a material warehouse-out distribution method and device, and the method comprises the steps: enabling a material warehouse management system to carry out the warehouse-out distribution of a material according to the total feeding amount of the needed material listed by a feeding list and the preset material carrying number of the material in each type of candidate material disc in a material warehouse when the total stock amount of the needed material meets the total feeding amount demand of the feeding list; establishing a tray distribution model; solving the charging tray distribution model through a particle swarm algorithm to obtain a plurality of groups of optimal solutions of the charging tray distribution model; and according to the storage location information of each type of candidate charging trays in the material warehouse, calculating the total delivery time duration of the candidate charging trays corresponding to all the optimal solutions of the charging tray distribution
