Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing AGV systems for transporting shelves in warehouses are inefficient in managing multiple tasks with varying priorities and require better utilization of buffer storage spaces to enhance operational efficiency.
Innovation Solution
A method and apparatus that utilize buffer storage spaces to decompose transporting routes into sections, allowing automated guided vehicles to manage tasks with varying priorities and optimize their use by selecting idle vehicles and managing buffer storage space allocation based on task priorities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If AGV systems transport shelves directly from storage to picking stations without buffer storage spaces, then the transportation process is simple, but the system cannot efficiently manage multiple tasks with varying priorities and vehicle utilization is low
Solution Approach 1:
The transportation route is decomposed into multiple sections by introducing buffer storage spaces between shelf storage and picking stations. This segmentation allows the system to break down complex transportation tasks into manageable segments, enabling priority-based task management and improving overall transportation efficiency without overwhelming the AGV system.
Solution Approach 2:
Buffer storage spaces are introduced as intermediary zones between shelf storage and picking stations. These buffer zones act as mediators that temporarily hold shelves, allowing the system to decouple the transportation process from immediate picking demands. This enables better task prioritization and AGV utilization by allowing shelves to wait in buffers rather than requiring immediate direct transport.
2Adaptability or versatility
If AGV systems use direct point-to-point transportation without buffer storage, then the system structure is simple, but task completion flexibility and hit rate are reduced
Solution Approach 1:
The transportation route is decomposed into multiple sections by introducing buffer storage spaces between shelf storage and picking stations. This segmentation allows the system to break down complex transportation tasks into manageable segments, enabling priority-based task management and improving overall transportation efficiency without overwhelming the AGV system.
Solution Approach 2:
Shelves are transported to buffer storage spaces in advance before actual picking operations. This preliminary action allows the system to prepare shelves ahead of time and store them in buffers, enabling flexible task prioritization and ensuring that shelves are ready when needed without requiring immediate direct transport to picking stations.
3Loss of time
If AGV systems prioritize urgent tasks dynamically, then task completion efficiency improves, but the control system complexity increases
Solution Approach 1:
Shelves are transported to buffer storage spaces in advance before actual picking operations. This preliminary action allows the system to prepare shelves ahead of time and store them in buffers, enabling flexible task prioritization and ensuring that shelves are ready when needed without requiring immediate direct transport to picking stations.
Solution Approach 2:
The system implements dynamic priority management by monitoring task urgency and adjusting transportation priorities in real-time. When urgent tasks are detected, the system provides feedback to re prioritize AGV assignments and route planning, ensuring that time-sensitive operations receive immediate attention while maintaining overall system efficiency.

AI summary
A method and apparatus for carrying a shelf. One specific implementation of the method comprises: receiving first task information from a task server (104); determining, according to an identifier of a shelf to be carried, the position of a shelf storage location (201) for storing the shelf as a starting point position; determining, according to an identifier of a first picking station, the position of a first temporary storage location in a temporary storage location set corresponding to the first picking station as an ending point position; generating first carrying information according to the determined starting point position and ending point position; and sending the first carrying information to automated guided vehicles (106,107), so that the automated guided vehicles (106, 107) carry the shelf. According to the implementation, the automated guided vehicles (106,107) can be used more fully.
