Work Site Vehicle Dispatch Control for Mixed Manned-Autonomous Fleets
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mixed operations of unmanned and manned vehicles at a work site, such as a mine, there is a challenge in maintaining work efficiency without reducing the operation rate of either vehicle during loading and soil discharging operations.
Innovation Solution
A management system that determines the presence of a manned vehicle in a predetermined area and outputs commands to allocate either vehicle to a work point, ensuring efficient operation by allocating loading points based on vehicle availability and position.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If unmanned vehicles and manned vehicles operate in a mixed manner at work places, then the operation flexibility and productivity are improved, but the coordination complexity and work efficiency decrease due to conflicts over work points
Solution Approach 1:
The management device serves as an intermediary between unmanned and manned vehicles, receiving position information from both types of vehicles and issuing coordinated work commands. This mediator resolves conflicts over work points by determining which vehicle should proceed based on their positions and issuing appropriate commands, thereby maintaining high operation rates while managing coordination complexity centrally rather than through direct vehicle-to-vehicle communication
2Productivity
If multiple vehicles are allocated to the same work point simultaneously, then the utilization rate of work places increases, but the safety and operational smoothness deteriorate due to vehicle conflicts
Solution Approach 1:
The system continuously receives position information from both unmanned and manned vehicles as feedback, and uses this real-time data to dynamically issue work commands. The management device monitors vehicle positions and adjusts command allocation to prevent conflicts at work places, ensuring that only one vehicle is commanded to proceed to a work point at any given time, thereby maintaining operational smoothness while maximizing work place utilization
Solution Approach 2:
The management device issues work commands in advance based on predicted vehicle positions and work place availability. By determining which vehicle should proceed to a work point before actual arrival, the system prevents conflicts from occurring and ensures smooth operations while maintaining high utilization of work places through proactive coordination

AI summary
A management system of a work site in which an unmanned vehicle and a manned vehicle operate in a mixed manner includes: a determination unit that determines whether or not the manned vehicle exists in a predetermined area of the work site; and a command unit that outputs a work command to cause the unmanned vehicle or the manned vehicle to travel to a work point set in a work place based on the determination result.
