Vehicle Management System Ride-Sharing Dispatch Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle management systems face inefficiencies in ride-sharing, leading to increased travel times and user dissatisfaction, as well as suboptimal vehicle assignment, which reduces system usage and dispatch efficiency.
Innovation Solution
A vehicle management system that calculates a second, longer arrival time for users, determines the service capacity by comparing this time to the initial arrival time, and uses this capacity to identify available areas for ride-sharing, allowing vehicles to deviate from their original routes to accommodate additional passengers while ensuring timely arrival at the designated destination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If ride-sharing is established by accepting the user's request, then the vehicle can serve more customers, but the required time to the destination increases and arrivals are delayed
Solution Approach 1:
The system performs preliminary calculations of service capacity and available ride-sharing areas before making dispatch decisions. By pre-determining the time buffer and geographic boundaries where ride-sharing is feasible, the system can quickly accept or reject ride-sharing requests without delaying the primary user's arrival time.
Solution Approach 2:
The system dynamically adjusts the service capacity parameter based on the difference between the original arrival time and the acceptable arrival time. By changing this time parameter, the system determines the maximum allowable deviation for ride-sharing routes, enabling flexible optimization of both productivity and arrival time.
2Loss of time
If a user does not accept a transfer request to avoid delay, then their arrival time is preserved, but a non-optimum vehicle is assigned to the requesting user and their arrival may be delayed
Solution Approach 1:
The system implements feedback mechanisms where users' acceptance or rejection of ride-sharing requests provides information about their time sensitivity. This feedback is used to refine service capacity calculations and improve future dispatch decisions, balancing individual arrival time requirements with overall vehicle dispatch efficiency.
Solution Approach 2:
The system dynamically adjusts vehicle assignments based on real-time conditions and user preferences. When a user rejects a ride-sharing request, the system immediately reassigns the vehicle to optimize for the requesting user, demonstrating dynamic adaptability that resolves the contradiction between preserving arrival time and maintaining dispatch efficiency.
3Reliability
If the system reduces use opportunities to maintain timely arrivals, then user satisfaction improves, but vehicle dispatch efficiency is lowered
Solution Approach 1:
The system segments the service area into zones where ride-sharing is permitted and zones where it is not, based on calculated available areas. This segmentation allows the system to maximize ride-sharing opportunities in suitable regions while guaranteeing timely arrivals in time-sensitive regions, thereby maintaining both reliability and productivity simultaneously.

AI summary
A vehicle management system (1) for managing a plurality of vehicles shared by a plurality of users, comprising: a controller (10) for accepting a use request for using the vehicle from the user and managing vehicle dispatch; and a database (20) for storing the use request including a departure place and a destination of the vehicle designated by the user, wherein the controller (10) calculates a required time for the vehicle to arrive at the destination designated by a first user who has made the use request as a first time, calculates a time which is a longer time than the first time and is a time to present to the first user, as a second time, calculates an available area for ride-sharing based on the service capacity, accepts the use request from the second user, and when the departure place designated by the second user is within the available area for ride-sharing, has the vehicle pass through the departure place designated by the second.
