Vehicle Dispatching System Using Arrival Time Comparison
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle dispatching systems face issues where empty vehicles are dispatched to users with shorter waiting periods, leading to longer wait times for users when empty vehicles arrive before them.
Innovation Solution
A vehicle dispatching system that calculates the arrival periods of both the user and available vehicles, designating a vehicle as the dispatch vehicle if its waiting period is shorter than the user's, ensuring the user arrives first.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the empty vehicle is dispatched as the new reserved vehicle when it arrives at the station before the user, then the vehicle dispatch efficiency is improved, but the user waiting period becomes longer
Solution Approach 1:
The controller calculates and compares waiting period differences between the reserved vehicle and empty vehicle before the user arrives at the boarding point. By performing this comparison in advance, the system can proactively designate the optimal vehicle (second vehicle) as the dispatch vehicle before the user arrives, preventing the user from experiencing long wait times while still improving overall dispatch efficiency through dynamic vehicle allocation
Solution Approach 2:
The system dynamically adjusts vehicle dispatch decisions based on real-time conditions. The controller continuously monitors the scheduled arrival periods of both the reserved vehicle and empty vehicle, and dynamically designates which vehicle should serve the user based on current waiting period differences. This dynamic approach allows the system to adapt to changing conditions and optimize both dispatch efficiency and user waiting time
2Loss of time
If the second vehicle is designated as the dispatch vehicle before the user arrives, then the user waiting period is shortened, but the control complexity increases
Solution Approach 1:
The controller performs the vehicle comparison and designation process before the user arrives at the boarding point. By calculating the waiting period differences in advance and making the designation decision proactively, the system simplifies the overall control process. This preliminary action prevents the need for complex real-time decision-making at the moment of user arrival, reducing control complexity while achieving shorter user waiting times
Solution Approach 2:
The system uses its own internal resources (controller with calculation capabilities) to automatically compare waiting period differences and make vehicle designation decisions. This self-service approach eliminates the need for external intervention or complex coordination with other systems, managing control complexity through automated internal processing while achieving optimal vehicle assignment

AI summary
A vehicle dispatching method is provided for managing a dispatch to a user of a first vehicle reserved by a user as a dispatch vehicle or a second vehicle that can be dispatched to a scheduled boarding point in which the user boards the dispatch vehicle, using a controller for communicating with communication devices in the first vehicle and the second vehicle. The method includes: acquiring, before the user arrives at the plan boarding point, position information of the first vehicle and position information of the second vehicle; calculating a first scheduled arrival period until the first vehicle arrives at the scheduled boarding point based on the acquired position information of the first vehicle; calculating a first waiting period difference between a user scheduled arrival period until the user arrives at the scheduled boarding point and the first scheduled arrival period; calculating a second scheduled arrival period until the second vehicle arrives at the scheduled boarding point for the user based on the acquired position information of the second vehicle; calculating a second waiting period difference between the user scheduled arrival period and the second scheduled arrival period; determining whether or not the second waiting period is shorter than the first waiting period; and when determining that the second waiting period is shorter than the first waiting period, designating the second vehicle as the dispatch vehicle.
