Vehicle Dispatch Management Using Durability Influence Index
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing dispatch management systems do not consider the durability of vehicles when determining which vehicle to dispatch, potentially leading to vehicles with durability issues being sent to users with driving plans that may exacerbate these issues.
Innovation Solution
A dispatch management device that calculates an influence index value based on a driving plan to assess the potential impact on vehicle durability and sets priorities for candidate vehicles such that those with lower durability indices are given lower priorities, ensuring that vehicles without durability problems are dispatched to users with plans that may affect durability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the dispatch management system selects candidate vehicles based only on position information and availability, then the dispatch efficiency is improved, but vehicles with durability issues may be dispatched to users with driving plans that could exacerbate these issues
Solution Approach 1:
The system changes the selection parameters by introducing durability indices and influence index values. Instead of only considering position and availability, the system now evaluates vehicles based on multiple parameters including total travel distance, acceleration/deceleration frequency, and the specific driving plan requirements. This multi-parameter approach allows the system to maintain high dispatch efficiency while avoiding vehicles with durability issues for demanding routes.
Solution Approach 2:
The system implements a feedback mechanism where the driving plan information (such as route characteristics, distance, and time constraints) is used to determine an influence index value that feeds back into the vehicle selection process. This feedback loop allows the system to adjust vehicle priority rankings based on how well the vehicle's durability status matches the demands of the specific driving plan, thereby preventing dispatch of vulnerable vehicles to unsuitable routes.
2Device complexity
If vehicles are dispatched without considering durability factors, then the dispatch process is simplified and faster, but the vehicle durability deteriorates due to mismatched driving plans
Solution Approach 1:
The system performs preliminary evaluation of vehicle durability status before dispatch by calculating durability indices based on total travel distance and operational history. The driving plan is also analyzed in advance to determine an influence index value that represents the potential impact on durability. This preliminary action ensures that durability considerations are integrated into the dispatch decision-making process without adding significant complexity during the actual dispatch execution.
3Reliability
If the system prioritizes vehicles with higher durability for all dispatch requests, then vehicle durability is protected, but dispatch efficiency decreases due to limited candidate vehicle selection
Solution Approach 1:
The system applies local quality by differentiating vehicle selection criteria based on the specific characteristics of each driving plan. Instead of uniformly prioritizing high-durability vehicles for all requests, the system calculates an influence index value for each driving plan that reflects its specific demands (such as route length, terrain, and time constraints). Vehicles are then prioritized locally according to how well their durability status matches the specific requirements of each request, optimizing both durability protection and dispatch efficiency for each individual case.

AI summary
The vehicle dispatch management device includes a processor configured to: determine an influence index value representing an influence degree on a decrease in durability based on a driving plan included in a dispatch request, set a priority for each of a plurality of candidate vehicles so that the priority becomes lower, as durability of the candidate vehicle represented by a durability index of the candidate vehicle is lower, in response to the influence index value, and determine a vehicle to be dispatched from among the plurality of candidate vehicles in response to the priority of each of the plurality of candidate vehicles.
