Embodiment Construction

[0111] According to the technical scheme of the present invention, this embodiment provides a method for establishing a cargo space allocation and dispatching model under a two-end type same-track double-vehicle operation mode (the layout structure diagram is as follows: figure 1 shown), this method reasonably allocates the goods to storage locations according to the attributes of out / in warehouse frequency, quality, and quantity, and realizes that the mathematical expectation of the running time of the two stackers performing outbound tasks is close to and minimized, and the overall center of gravity of the shelf is Low, the total quality of the grouped shelves is close to each other. At the same time, in the subsequent optimization algorithm, the initial population quality of the algorithm is better by adopting the priority strategy of the goods location. The specific optimization algorithm is an integrated multi-objective biogeographical optimization algorithm. stage has goo...

Abstract

The invention discloses a goods allocation distribution scheduling model establishing method in a two-end same-rail double-vehicle operation mode. According to the method, goods is reasonably distributed to available goods allocations according to the warehouse outbound / inbound frequency, mass and quantity attributes, mathematical expectations of the operation time of two stackers for executing warehouse outbound tasks are close to each other and are the minimum, the integral gravity center of the shelves is low, total masses of the shelf sets are close to each other, in a subsequent optimization algorithm, the goods allocation priority strategy is employed to make initial population mass of the algorithm be more optimal, the specific optimization algorithm is an integrated multi-target biogeography optimization algorithm, and excellent performance at any optimization solution phase is realized. Goods allocations with the high warehouse outbound / inbound frequency are arranged nearby two warehouse outbound / inbound stations, the integral gravity center is low, the total masses of the shelf sets are close to each other, and actual same-rail double-vehicle condition demands can be satisfied.

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-vehicles on the same track at both ends. Background technique [0002] Storage space allocation refers to placing goods in appropriate storage spaces according to actual production needs, which is a key issue that affects 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 imp...
