Warehouse Dispatching Snapshot for Conflict-Free Task Generation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The processing of item-picking dispatching requests in warehouses is prone to errors due to updates in status information stored in context containers, which can lead to conflicts and errors during the generation and execution of dispatching tasks.
Innovation Solution
A method that involves determining the type of dispatching request, generating mirror-image information of the target picking resource status, and using this mirror-image information to create a dispatching task, thereby avoiding the impact of updated status information on the dispatching process, and includes error checking and conflict resolution mechanisms to ensure accurate task generation and execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If status information in the context container is updated in real time during dispatching task generation, then the system maintains high adaptability to changing warehouse conditions, but errors occur in processing the dispatching request due to conflicting status information
Solution Approach 1:
The patent applies the copying principle by creating a snapshot copy of the status information from the context container at the moment the dispatching request is received. This snapshot is stored in a local data structure, allowing the system to process the dispatching request based on this frozen copy rather than the continuously updating real-time status information. This resolves the contradiction by enabling the system to maintain adaptability through real-time updates while ensuring reliability by processing decisions based on a stable, non-changing snapshot of the status at the time of request.
2Productivity
If the system continuously monitors and updates status information in real time, then the productivity of item picking operations is improved, but the complexity of managing and processing dispatching requests increases
Solution Approach 1:
The patent applies segmentation by separating the status information management into two distinct segments: the real-time updating context container that maintains current warehouse status, and the local snapshot data structure that stores a frozen copy for processing. This segmentation allows the system to maintain high productivity through continuous real-time monitoring while reducing processing complexity by working with a static, simplified copy of the status information during dispatching task generation.

AI summary
Methods, devices, and apparatus, including computer programs encoded on computer storage media, for processing an item-picking dispatching request are provided. One of methods includes receiving a dispatching request with respect to item picking; determining a type of the dispatching request; determining, in stored picking resource status information, target picking resource status information corresponding to the type of the dispatching request according to a preset correspondence between types of dispatching requests and picking resource status information, wherein the stored picking resource status information is updated in real time; generating mirror-image information of the target picking resource status information; and generating a dispatching task for item picking based on the mirror-image information of the target picking resource status information.
