Goods location allocating method applied to automatic warehousing system of multi-layer shuttle vehicle

Abstract

The invention discloses a goods location allocating method applied to an automatic warehousing system of a multi-layer shuttle vehicle. The method comprises the following steps: firstly, according to the quantities of goods shelves and tunnels, generating plane layout structure data of the system; then analyzing the waiting time of the shuttle vehicle executing an outbound task as well as the idle time of a hoister; establishing an open queuing network model for describing the system; analyzing the relationship among the waiting time of the shuttle vehicle, the idle time of the hoister and the time of inbound and outbound works by a decomposition process; determining that the higher the reaching rate of a task serviced by the shuttle vehicle is, the lower the goods location of the task is, and the goods with highest correlation are allocated at different layers, so that multiple shuttle vehicles can provide service simultaneously; finally putting forward a principle of dividing storage zones in light of item correlation, establishing a correlation matrix of outbound items, clustering the items by an ant colony algorithm, and combining and arranging the storage zones in a two-dimensional plane according to the analysis result of the queuing network model, thereby realizing the allocation of goods location. By the method, the waiting time of the shuttle vehicle and the idle time of the hoister can be effectively shortened, so that the rate of equipment utilization and the throughput capacity of a distribution center are increased.

Description

technical field [0001] The invention relates to the technical field of logistics, in particular to a method for dynamic cargo location allocation of an automatic storage system for multi-layer shuttle vehicles. Background technique [0002] Most of the location allocation methods of traditional automated three-dimensional warehouses are based on random storage, positioning storage, and classified storage strategies. In order to reduce the travel time of the stacker to complete the entry and exit of goods, the goods with high frequency of entry and exit should be placed outside the I / O In order to increase the stability of the cargo in the cargo space near the platform, the heavy cargo should be placed on the lower floor. However, because the multi-storey shuttle car automatic storage system has the characteristics of parallel pick-up and serial out-of-warehouse, it changes the operation mode of the traditional automated three-dimensional warehouse, making the goods distribut...

Problems solved by technology

However, because the multi-storey shuttle car automatic storage system has the characteristics of parallel pick-up and serial out-of-warehouse, it has changed the operation mode of the traditional automated three-dimensional warehouse, making the goods distribution method of the traditional automatic three-dimensional warehouse unable to adapt to the multi-storey shuttle car automatic storage system.
