Problems solved by technology

In this case, if the conveyor buffer is too long and exceeds the theoretical buffer capacity under the maximum delivery efficiency, the equipment will take up too much space and cause resource waste; if the conveyor buffer is too short, it will not meet the maximum delivery efficiency. The theoretical cache volume under efficiency will lead to out-of-stock phenomenon when the material box cannot be replenished in a short period of time, which will affect the picking efficiency

Abstract

The invention discloses a multi-layer shuttle vehicle system conveyor cache length modeling and optimizing method, and the method comprises the steps: a buffer memory input and output balance model ofthe conveyor is built on the basis of deeply analyzing the warehouse-out operation process of the multilayer shuttle vehicle system; and under the condition that the conveyor cache meets the normal operation of the sorting operation, an optimal condition and a critical condition of the cache length are provided. A material box warehouse-out operation process is analyzed through an open-loop queuing network modeling method, a material box average warehouse-out time model is established, and an optimization model of the buffer length of the conveyor is established according to the relation between material box warehouse-out operation flow distribution and the manual picking efficiency; in order to shorten the average warehouse-out time of the material box, k-means algorithm and a storage area arrangement rule are utilized to optimize storage positions, and the buffer length of the conveyor is reduced.

Description

technical field [0001] The disclosure relates to a method for modeling and optimizing the buffer length of a conveyor in a multi-layer shuttle system. Background technique [0002] With the significant improvement in the level of intelligence and automation in the logistics industry, the integrated storage and distribution system of multi-storey shuttle vehicles has been widely used in e-commerce and manufacturing industries. When the system is in and out of the warehouse, in order to prevent interruption of operations and improve order picking efficiency, a certain length of conveyor is set up at the handover section between the hoist and the manual picking platform to buffer the boxes in and out of the warehouse. [0003] The conveyor buffer is mainly used to temporarily store the bins waiting to be picked out of the warehouse, so as to reduce the waiting time between devices. During the research process, the inventor found that the speed at which material boxes arrive at...
