Establishment method of cargo space allocation and dispatching model under double-vehicle operation mode with two ends of the same track

Abstract

The invention discloses a method for establishing a cargo space allocation and dispatching model under the two-terminal double-vehicle operation mode on the same track. The method reasonably allocates goods to storage spaces according to the attributes of out / in warehouse frequency, quality, and quantity, and realizes two The mathematical expectation of the running time of the stacker to perform the outbound task is close to and minimum, the overall center of gravity of the shelf is low, and the total mass of the group of shelves is close. At the same time, in the subsequent optimization algorithm, the initial population quality of the algorithm is better by using the priority strategy of the location , the specific optimization algorithm is an integrated multi-objective biogeography optimization algorithm, which has good performance in any stage of optimization solution. The goods with high frequency of out / in storage are stored near the two out / in warehouses, the overall center of gravity of the shelves is low, and the total mass of the groups of shelves is similar, which can meet the actual working condition of "two cars on the same track".

Description

technical field [0001] The invention belongs to the category of establishing a cargo space allocation scheduling model in the field of automatic three-dimensional warehouse scheduling, and in particular relates to a method for establishing a cargo space allocation scheduling model under the operation mode of double-cars on the same track with two ends. Background technique [0002] Storage space allocation refers to placing goods in suitable storage spaces according to actual production needs, which is a key issue affecting the storage efficiency and structural stability of large-scale industrial three-dimensional warehouses. In production logistics, large-scale industrial three-dimensional warehouses mostly adopt a centralized storage / retrieval management method. The aisles are long and deep, and the storage / retrieval efficiency of a single stacker is low. In order to shorten the distance between the out / in warehouse and the storage point deep in the shelf, and improve the ...

AI Technical Summary

Problems solved by technology

In view of this feature, the storage space allocation and scheduling model that is suitable for the independent operation of a single stacker and the storage efficiency priority principle is no longer suitable for the two-end operation mode of the same track.
