[0003] At present, the shuttle car storage system at home and abroad still only stays at the single-floor operation level, that is, maintaining one shuttle car per floor and each lane. When the order or task volume is small, most of the shuttle cars are in an idle state. Undoubtedly increased the investment cost of the enterprise, resulting in an unreasonable waste of materials; due to the excessive cost of reconstruction after the storage system is completed, the enterprise strives to have a prior estimate of the reasonable layout of the storage system and the physical parameters of the equipment in the initial stage of construction and decision

Embodiment Construction

[0047] Attached below Figure 1-9 and specific implementation methods, the present invention will be further explained.

[0048] A resource allocation optimization method for a four-way shuttle-type intensive storage system of the present invention comprises the following steps:

[0049] Step 1. Transform the resource allocation system of the shuttle-type intensive storage system into a model under the OXYZ coordinate system;

[0050] Take the I / O platform of the storage system as the coordinate origin O; take the running direction of the shuttle car’s cargo storage lane as the X-axis, when the shuttle car runs on the X-axis, it can reach different rack rows; take the running direction of the main channel of the shuttle car as the Y-axis, the shuttle car When the Y-axis is running, it can reach different shelf rows; if the vertical running direction of the elevator is the Z-axis, when the elevator is running vertically on the Z-axis, it can reach different shelf layers;

Abstract

The invention discloses a resource configuration optimization method for a four-way shuttle-type intensive storage system. First, multiple optimization objectives and decision variables involved in the configuration optimization of the storage system are determined; then, according to the storage operation mode and decision variables, each The mathematical model of the optimization target; finally, according to the established mathematical model of each optimization target, a multi-objective optimization model of resource allocation is established, the decision variable is solved by using the multi-objective optimization method, and the configuration of the storage system is optimized in combination with the solution result; the present invention By analyzing the relevant design variables that affect the investment cost and operating cost of the storage system and the throughput of the storage system, a multi-objective optimization model is established to optimize the resource allocation in the storage system, providing a strong basis for the design of the warehouse in the initial planning of the enterprise, and reducing the cost. Reduce the investment cost and logistics cost of the enterprise, improve the operating efficiency of the intensive storage system, and thus improve the economic benefits of the enterprise.

Description

technical field [0001] The invention belongs to the field of configuration optimization of dense storage systems, and in particular relates to a resource configuration optimization method of a four-way shuttle type dense storage system. Background technique [0002] With the rapid development of the domestic economy and the increasing shortage of construction land resources, considering how to store the largest amount of items in a limited space, increase the storage capacity rate and make the storage system more automated, intensive and intelligent, more and more companies are beginning to use it. The automated warehouse combined with new logistics equipment, Shuttle-based compact storage&retrieval system (SB-CS / RS) came into being and has been widely used in enterprises. [0003] At present, the shuttle car storage system at home and abroad still only stays at the single-floor operation level, that is, maintaining one shuttle car per floor and each lane. When the order or ...
