Warehouse Goods-Picking Task Assignment via Transport Vehicle Path Planning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional goods-picking methods in warehouses result in inefficient work processes due to excessive walking distances for personnel and inflexible conveyor line deployments, leading to low efficiency.
Innovation Solution
A method and device that associate goods-picking tasks with transport vehicles based on overlapping storage site passages, calculate optimal paths for vehicles, and assign tasks to available personnel, reducing unnecessary walking by utilizing transport vehicles to reach storage sites and allowing personnel to move to the next task location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If one goods-picking person independently completes all goods-picking tasks, then the task can be completed without relay coordination, but the invalid walking distance of the person becomes too long
Solution Approach 1:
The patent divides the warehouse into multiple zones with multiple goods-picking persons, each responsible for specific storage sites. This segmentation reduces the walking distance for each person while maintaining operational simplicity through clear task allocation.
Solution Approach 2:
The patent introduces a conveyor line as an intermediary to transport goods between different zones. This allows goods-picking persons to remain in their respective zones rather than traveling across the entire warehouse, reducing invalid walking distance while maintaining task completion efficiency.
2Productivity
If multiple goods-picking persons complete the goods-picking task in relay via conveyor line, then the invalid walking distance is reduced, but the deployment of the conveyor line becomes inconvenient and inflexible
Solution Approach 1:
The patent makes the system dynamic by allowing flexible assignment of goods-picking tasks to different persons based on real-time location and availability. The task allocation is not fixed but adapts to changing conditions, providing flexibility without requiring physical reconfiguration of conveyor lines.
Solution Approach 2:
The goods-picking persons serve multiple functions: they can pick goods from their assigned zones, receive tasks dynamically allocated by the system, and work in coordination with the conveyor line when needed. This multi-functionality provides operational flexibility without requiring dedicated infrastructure for each function.
3Productivity
If multiple goods-picking persons are deployed in different areas, then the invalid walking distance is reduced, but the task coordination and task passing becomes more complex
Solution Approach 1:
The patent implements a feedback mechanism where the system continuously monitors the location and task completion status of goods-picking persons. Based on this feedback, the system dynamically reallocates tasks to optimize workflow and minimize coordination complexity, automatically managing the complexity rather than increasing it.
Solution Approach 2:
The system automatically performs task allocation and coordination without requiring manual intervention. The goods-picking persons simply execute assigned tasks while the system handles the complex coordination logic, effectively making the system self-manage the coordination complexity.

AI summary
A goods-picking method and device relate to the field of computer technology. The method comprises: acquiring order information to construct a goods-picking task (S101); associating one or more goods-picking tasks with the same transport vehicle according to an overlapping degree of passages where goods-picking storage sites between the goods-picking tasks are located (S102); acquiring all goods-picking storage sites of the goods-picking tasks of the transport vehicle, and then calculating a path for the transport vehicle (S103), wherein the path comprises at least one goods-picking parking spot, each of which corresponds to at least one goods-picking storage site; and receiving location information of available goods-picking persons and a goods-picking parking spot where the transport vehicle is currently located, calculating an available goods-picking person matching the transport vehicle, and sending a goods-picking task associated with the transport vehicle to the available goods-picking person for execution (S104). The method can solve the problem of low goods-picking work efficiency in the prior art.
