Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing inspection logistics systems face challenges in optimizing the scheduling of inspection logistics, leading to inefficiencies in the movement and inspection of materials across multiple facilities.
Innovation Solution
The proposed inspection logistics system includes a controller with a facility status updating unit, a node recursive search unit, and a weight determination unit. This system optimizes the scheduling by updating facility statuses, searching for nodes and updating information, and selecting inspection facilities based on updated weights.

Engineering Contradiction Analysis
1Productivity
If a traditional scheduling system is used for inspection logistics, then the system structure is simple, but the logistics optimization efficiency is poor
Solution Approach 1:
The controller is divided into distinct functional modules: facility status updating unit, node recursive search unit, and weight determination unit. Each module performs a specific function in the scheduling optimization process, transforming a monolithic system into manageable segments that work together to achieve efficient logistics optimization.
Solution Approach 2:
The system dynamically updates facility statuses and recalculates optimal paths in real-time based on changing conditions. The node recursive search unit continuously explores available paths and the weight determination unit adjusts scheduling decisions based on current facility states, making the system adaptive rather than static.
2Measurement precision
If real-time facility status updates are implemented, then the scheduling accuracy is improved, but the computational load increases
Solution Approach 1:
The system pre-configures the node recursive search structure and establishes the framework for weight calculation before actual scheduling decisions are needed. By preparing the search topology and update mechanisms in advance, the system reduces the computational burden during real-time operations while maintaining accurate scheduling.
3Productivity
If the node recursive search method is used to find optimal paths, then the logistics path optimization is improved, but the search time increases
Solution Approach 1:
The node recursive search focuses computational resources on locally relevant paths and facilities rather than exhaustively searching the entire system. By concentrating the search on pertinent nodes and connections, the system achieves effective path optimization without requiring excessive search time across the complete network.

AI summary
An inspection logistics system includes a plurality of inspection facilities, a linear motion system including a plurality of coils that move inspection objects placed on a carrier to the plurality of inspection facilities, and a controller that controls movement of the carrier. The controller includes a facility status update unit that updates a status of the plurality of inspection facilities, a node recursive search unit that searches for nodes composed of connections between the plurality of coils and updates information existing from a search start point to a reachable inspection facility, and a weight determination unit that selects an inspection facility to which the carrier will move based on a facility status updated by the facility status update unit and information updated by the node recursive search unit.
