Embodiment Construction

[0055] The present invention is described in detail below in conjunction with accompanying drawing:

[0056] In a single outbound task, the task first requests the response of the shuttle car on the corresponding floor. According to the system scheduling, the shuttle car first moves horizontally to the delivery location assigned by the system, uses the fork to take out the goods, and then the shuttle car runs to the first column of the floor, requesting the response of the roadway hoist. Similarly, the hoist goes to the corresponding floor to complete the handover of goods with the shuttle car according to the system scheduling. The outbound task process is as follows: figure 2 shown.

[0057] Based on this, the present invention discloses a modeling optimization method based on an automatic storage system of a multi-storey shuttle, comprising the following steps:

[0058] (1) Model the multi-storey shuttle car automatic storage system, extract the number of layers, the num...

Abstract

The invention discloses a modeling optimization method based on a multilayer shuttle vehicle automatic storage system. The modeling optimization method includes the steps that the motion law of elevators and shuttle vehicles as well as various sorts of service time in the operating process of the elevators and the shuttle vehicles are determined; the number of layers of the multilayer shuttle vehicle automatic storage system, the depth of a roadway, the height of each single-layer storage rack, the width of each single cargo box, the speed and accelerated speed of each elevator, the speed andaccelerated speed of each shuttle vehicle, the cargo collecting and putting time at a time and the delivery task detailed information parameters are extracted, and a mathematical model of the multilayer shuttle vehicle automatic storage system is established; a mixed integer programming model by using obtainment of the shortest cargo collecting total time as the target is established; and a GUROBIlinear programming solver is used for solving the mixed integer programming model, and accordingly the shortest cargo collecting total time and the optimal cargo collecting sequence of the system canbe obtained. By adoption of the modeling optimization method, the system performance under various storage racks and equipment configurations can be estimated quickly, and decision support is provided for accurately designing the system, increasing the equipment utilization rate and reducing the operating cost.

Description

technical field [0001] The invention relates to the technical field of automated three-dimensional warehouses, in particular to a modeling optimization method based on an automatic storage system of a multi-layer shuttle vehicle. Background technique [0002] In the traditional automated three-dimensional warehouse, the stacker is responsible for the storage and retrieval of goods, so the modeling of the traditional automated three-dimensional warehouse only needs to analyze the single equipment of the stacker. [0003] With the development of orders to small batches and multi-batches, the automatic storage system of multi-storey shuttle vehicles is gradually put into use. Compared with the traditional automated three-dimensional warehouse, the multi-storey shuttle car automatic storage system uses elevators and shuttle cars to pick up goods, which greatly improves work efficiency. Such as figure 1 As shown, the multi-storey shuttle car automatic storage system is equipped...
