Train Diagram Adjustment via Minimum Interval Sorting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for adjusting train diagrams by adding extra trains are less automatic and error-prone, lacking objective evaluation and being subjective in nature.
Innovation Solution
A method and apparatus that involve obtaining a first time corresponding to a target passenger flow, adjusting the departure times of trains based on a preset minimum departure time interval, and performing an extra train adding instruction to create an adjusted train diagram, which includes sorting trains and determining adjustments based on specific conditions to ensure a rational and automated process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the dispatcher manually draws the train diagram and informs train drivers, then the train diagram can be adjusted, but the process is less automatic and error-prone
Solution Approach 1:
The system automatically adjusts the train diagram by selecting trains from the candidate set, calculating adjusted departure times based on the minimum departure time interval, and generating the adjusted train diagram without requiring manual dispatcher intervention for each adjustment step
Solution Approach 2:
The manual mechanical process of drawing and communicating train diagram changes is replaced by an automated computer-based system that performs calculations, generates diagrams, and transmits information electronically to train drivers
2Adaptability or versatility
If the dispatcher manually adjusts the train diagram, then flexibility is maintained, but the process is subjective without objective evaluation
Solution Approach 1:
The system uses objective parameters such as the minimum departure time interval and passenger flow data to determine train adjustments, replacing subjective dispatcher judgment with quantifiable criteria that can be consistently applied and evaluated
3Quantity of substance
If multiple trains are added to handle large passenger flow, then passenger capacity increases, but the complexity of coordinating departure times increases
Solution Approach 1:
The system applies different adjustment strategies to different trains based on their specific situations - trains in the candidate set are selected and adjusted according to their individual departure times and the minimum interval requirement, rather than applying a uniform approach to all trains
Solution Approach 2:
The system changes the departure time parameter of selected trains from the candidate set while maintaining the minimum departure time interval constraint, allowing multiple trains to be added or adjusted without creating scheduling conflicts
