Dynamic Embarking Duration Model for Railway Delay Estimation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern railway systems face challenges in maintaining predictable schedules and high accuracy due to unforeseen occurrences like broken doors, which lead to increased train stop times and delays, especially during rush hours, resulting in penalties for operators.
Innovation Solution
A method for determining the duration of embarking and disembarking processes using a spatially discreet dynamic model, such as a cellular automaton or social force model, to estimate delays and optimize train operations, even with non-functional doors, by calculating operating times and schedules accurately.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If doors are monitored with sensors to detect current situation, then door status monitoring is improved, but preventive estimation of increased time due to broken doors is not performed
Solution Approach 1:
The patent applies preliminary action by using sensors to detect door status issues before they cause complete failures, and by pre-calculating the impact on embarking/disembarking times. The system proactively identifies potential problems and prepares timing adjustments in advance, preventing complete operational disruptions and enabling operators to plan accordingly.
2Reliability
If reduced number of working doors occurs, then door functionality is degraded, but embarking and disembarking time increases
Solution Approach 1:
The patent implements feedback by continuously monitoring door status with sensors and using this information to dynamically adjust the calculated embarking/disembarking times. The system receives feedback on actual door conditions and refines its timing predictions, allowing operators to make informed decisions about schedule adjustments and resource allocation.
3Productivity
If train stop time increases due to reduced working doors, then operational efficiency is reduced, but penalty costs increase
Solution Approach 1:
The patent applies preliminary action by calculating and predicting the impact of door failures on train stop times before actual delays occur. This enables operators to take preventive measures such as adjusting schedules, reallocating resources, or preparing alternative arrangements, thereby minimizing actual delays and avoiding penalty costs associated with missed deadlines.
