Circulating Bus Schedule Switching for Failure Recovery
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current technologies for managing the operation of multiple vehicles on a circulation route face challenges in efficiently handling vehicle failures, which can disrupt pre-planned schedules and reduce the effectiveness of maintenance operations.
Innovation Solution
A server-based operation management system that monitors the status of circulating buses and revises their schedules to introduce a substitute bus into the route when a failing bus has not completed a specified number of laps, ensuring continuous operation and maintaining the scheduled number of buses on the route, while allowing for efficient maintenance and refueling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a vehicle traveling on the circulation route experiences failure, then the vehicle can be switched with another vehicle on standby, but the pre-planned operation schedule is adversely affected
Solution Approach 1:
The system pre-calculates and stores multiple alternative schedules before failure occurs. When a vehicle fails, the server selects from these pre-prepared alternative schedules rather than creating a new one in real-time, reducing schedule disruption while maintaining operational continuity
Solution Approach 2:
The operation schedule is made dynamic and adaptable. Instead of a fixed rigid schedule, the system can switch between multiple pre-defined alternative schedules based on real-time vehicle status, allowing the schedule to adapt to failures while minimizing disruption
2Productivity
If the operation schedule is revised to introduce a substitute bus, then the required number of buses on the route is maintained, but the server load for revisions increases
Solution Approach 1:
Multiple alternative schedules are pre-calculated and stored before any failure occurs. The server only needs to select from these pre-prepared options rather than performing complex real-time optimization, reducing server load while maintaining route continuity
Solution Approach 2:
The system creates multiple copies of alternative schedules in advance. When a failure occurs, the server simply copies and applies one of the pre-existing alternative schedules rather than generating a new one, significantly reducing computational complexity

AI summary
An operation management method for managing a plurality of circulating buses, each circulating bus being introduced into a circulation route from a base and returning to the base to be switched with another circulating bus after traveling a specified number of laps, includes storing, by a server, an operation schedule of the plurality of circulating buses, monitoring, by the server, a status of the plurality of circulating buses, and revising, by the server, the operation schedule when a first circulating bus traveling on the circulation route experiences failure before completing a specified number of laps, the operation schedule being revised so that a second circulating bus is introduced into the circulation route and returns to the base to be switched with a third circulating bus before completing the specified number of laps.
