Vehicle Dispatching Priority Ranking for Fair Task Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current taxi dispatching systems fail to equally distribute the chances of accepting vehicle service tasks among different companies, leading to inefficient allocation of resources and potential delays in passenger pickup.
Innovation Solution
A vehicle-dispatching method and system that establishes a database and dispatching priority ranking table in a service center, allowing for the selection of vehicles based on specific conditions and priorities, with the ability to adjust priorities after task acceptance, ensuring fair distribution of service requests.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the service center inquires all taxi drivers by wireless communication when a taxi call message is received, then the passenger can be dispatched quickly, but the chances of accepting tasks are not equally distributed among different vehicle-dispatching companies
Solution Approach 1:
The service center pre-establishes a dispatching priority ranking table that ranks vehicles from different dispatching companies in a predetermined order. This preliminary arrangement ensures that when a service request arrives, the system can quickly select from the ranked list without needing to inquiry all drivers, thus maintaining fast dispatching while ensuring fair distribution of opportunities across companies through the pre-established ranking structure.
2Productivity
If the service center selects vehicles based on a fixed priority ranking, then the dispatching process is simple and fast, but the system cannot adapt to changing vehicle availability and service conditions
Solution Approach 1:
The dispatching priority ranking table is designed to be dynamically adjustable. After a vehicle accepts a service task, the system automatically adjusts the ranking by promoting the next vehicle from the same dispatching company to maintain the fair distribution of opportunities. This dynamic adjustment allows the system to adapt to changing conditions while maintaining efficient dispatching operations.
Solution Approach 2:
The system incorporates feedback mechanisms where vehicle service confirming signals are received and processed to update the dispatching priority ranking table. This feedback loop ensures that the system continuously adapts to the current state of vehicle availability and service conditions, maintaining both efficiency and fairness in the dispatching process.
3Reliability
If the service center maintains a comprehensive database of all vehicles with their dispatching conditions, then the system can make informed selection decisions, but the system complexity increases
Solution Approach 1:
The system segments the vehicle information into structured dispatching condition sets for each vehicle, stored in an organized database. This segmentation allows the service center to efficiently query and filter vehicles based on specific conditions without managing a monolithic complex data structure. The segmented approach maintains reliability by ensuring comprehensive vehicle information is available while reducing system complexity through organized data management.

AI summary
A vehicle-dispatching system includes a service center and a plurality of hosts disposed in respective vehicles. For equally distributing the chances of accepting a reserved vehicle service task, a vehicle-dispatching method is provided. Firstly, the service center is in communication with the hosts of respective vehicles, thereby establishing a database and a dispatching priority ranking table. When the service center receives a vehicle service request, a vehicle is selected from the database according to the dispatching priority ranking table. If the host of the selected vehicle receives the inquiry signal and consents to accept a vehicle service task, a vehicle service confirming signal is issued from the host of the selected vehicle. When the service center receives the vehicle service confirming signal from the host of the selected vehicle, the host of the selected vehicle is adjusted to a lower priority ranking in the dispatching priority ranking table.
