Solution Overview

Problem

In complex terminal stations with many tracks, it is challenging to allocate tracks to train lines according to a preset rule, especially when trains from multiple companies operate on the same line section, leading to unclear allocation rules and complications in creating an automatic track use plan.

Innovation Solution

A device comprising a selector and an allocator that identifies the schedule line for a target train and allocates a track based on the train's classification and destination, prioritizing the track with the shortest operation headway if the initial allocation is not possible, thereby ensuring efficient crossover or continuation of trains.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Extent of automation

If a preset rule is used to allocate tracks to train lines in terminal stations with many tracks, then the allocation process becomes automated, but the allocation rule becomes unclear and difficult to apply

Engineering Contradiction:
Improvetrack allocation automationVSAvoidallocation rule clarity
Core Design Contradiction:
Extent of automationVSEase of operation

Solution Approach 1:

The patent segments the track allocation process into multiple decision stages: first selecting candidate tracks based on train classification, then selecting from those candidates based on operation headway. This segmentation makes the complex allocation rule clear and applicable by breaking it into manageable steps that can be automatically executed.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If tracks are allocated sequentially from empty tracks in terminal stations with many tracks, then the allocation process is simple, but the time required for train operations increases

Engineering Contradiction:
Improveallocation process simplicityVSAvoidtrain operation time
Core Design Contradiction:
Ease of manufactureVSLoss of time

Solution Approach 1:

The patent changes the selection parameters from simple sequential allocation to a two-parameter system: first filtering by train classification matching, then selecting based on minimum operation headway. This parameter-based approach optimizes train operation time while maintaining procedural clarity for automation.

Inventive Principle:
Principle #35Parameter changes

3Productivity

If trains from multiple companies operate on the same line section, then the station handles more traffic, but the track allocation becomes more complex and difficult to automate

Engineering Contradiction:
Improvestation traffic capacityVSAvoidtrack allocation complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent segments the complex multi-company allocation problem into hierarchical stages: first grouping tracks by train classification types, then applying headway optimization within each group. This segmentation reduces the overall complexity while maintaining high traffic capacity handling capability.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies different allocation criteria to different situations: train classification matching is applied as the primary filter, while operation headway optimization is applied as the secondary selection criterion. This local application of different quality standards simplifies the overall complex allocation process.

Inventive Principle:
Principle #3Local quality

AI summary

A device for creating a track use plan of an embodiment includes a selector and an allocator. The selector selects a schedule line of a target train to which a track of a station is to be allocated out of a plurality of the schedule lines included in a schedule of the station. The allocator allocates, to the schedule line of the target train, the track according to a track condition indicating an attribute of a train allocatable to the track, and allocates, to the schedule line of the target train, the track having a shortest operation headway out of a plurality of the tracks on the basis of an operation headway on each track between the target train and a preceding train preceding the target train when the track cannot be allocated to the schedule line of the target train according to the track condition.
