Problems solved by technology

However, most domestic and foreign scholars' research on shuttle vehicles is mostly based on static scheduling, and rarely involves dynamic mixed scheduling. The stacker-type three-dimensional warehouse and the current imperfect shuttle-type shelves can no longer meet the needs of today's market

Embodiment Construction

[0027] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] The hybrid scheduling optimization method of the double lifting platform elevator and the shuttle cart provided by the present invention is specifically implemented according to the following steps:

[0029] Step 1 establishes a reasonable mathematical model for the dispatching of the double lift platform elevator and the shuttle cart to which a single picking platform belongs;

[0030] 1.1 Analyze and study the multi-storey shuttle-type automated three-dimensional warehouse, and formulate goods picking rules

[0031] see figure 1 , figure 2 , The multi-storey shuttle car type automated three-dimensional warehouse includes an elevator 5, a shuttle cart 2, a buffer area 3 and an I / O location 9 (input / output). Among them, the elevator lifts the goods in the vertical direction, and the shuttle cart transports the goods along the roadway. The ...

Abstract

The invention discloses a hybrid optimal scheduling method for a dense warehousing system. The hybrid optimal scheduling method comprises the following steps: establishing a reasonable mathematical model for the picking and delivery scheduling condition of a multi-layer shuttle type goods shelf, optimizing the delivery scheduling condition, and then determining the optimal sequence for picking goods. The hybrid optimal scheduling method has the advantages that a genetic algorithm is adopted for optimizing a delivery model, so that the access travel time can be greatly shortened, the time cost can be obviously reduced, the energy consumption can be lowered, the high efficiency, high density, high availability and other advantages of an automatic three-dimensional warehouse with the multi-layer shuttle type goods shelf can be sufficiently exerted, the automatic three-dimensional warehouse can be subjected to real-time and online optimal scheduling, and the actual application value is relatively great.

Description

technical field [0001] The invention belongs to the technical field of intensive storage outbound picking and dispatching, and in particular relates to an optimal dispatching method for an intensive storage system combining a double lift platform elevator and a shuttle cart. Background technique [0002] With the rapid development of science and technology and industrial production, and based on the rise of the concept of "intensive storage", the requirements of modern enterprises for production, warehousing and distribution have been continuously improved, and the storage method has changed from the simple accumulation of manual work at the beginning to the use of forklifts, etc. The warehouse-style storage of simple equipment is improved to the three-dimensional warehouse storage that currently uses automation equipment such as high-position forklifts, unmanned guided vehicles AGV, and shuttle vehicles. Rail shuttle vehicle (RGV) is playing an increasingly important role i...
