Solution Overview

Problem

Current resource management plans in railroad and aviation industries face inefficiencies due to manual creation processes and lack of systematization, particularly in maintaining regularity of vehicle and crew management, leading to disruptions when operational schedules change.

Innovation Solution

A computer-based resource management plan creation device that generates a network model of transport routes and resource allocation, ensuring that management completion sites remain unchanged from the original plan by identifying merge candidates and adjusting resource allocation paths to maintain operational continuity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If manual creation of resource management plan is used, then flexibility in handling individual cases is maintained, but systematization and regularity of management deteriorates

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent replaces manual mechanical planning processes with an automated computer-based system that uses network models and algorithms to generate resource management plans, thereby achieving systematization while maintaining adaptability through configurable parameters and constraint conditions

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Adaptability or versatility

If resource allocation is adjusted to respond to schedule disruptions, then operational responsiveness is improved, but management completion site regularity deteriorates

Engineering Contradiction:

Improveoperational responsivenessVSAvoidmanagement completion site regularity

Core Design Contradiction:

Adaptability or versatilityVSStability of the object's composition

Solution Approach 1:

The patent implements dynamic resource allocation through a network model that can adapt to schedule disruptions while maintaining management completion site regularity, allowing the system to respond to changes without compromising the established pattern of resource management completion locations

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system changes parameters such as resource allocation paths and timing while maintaining the management completion site as a fixed constraint, enabling operational responsiveness without disrupting the regularity of where management completion occurs

Inventive Principle:

Principle #35Parameter changes

3Stability of the object's composition

If automated plan creation is implemented, then systematization and regularity of management is improved, but handling of complex individual cases deteriorates

Engineering Contradiction:

Improvesystematization and regularity of managementVSAvoidcomplexity of handling individual cases

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent segments the complex resource management planning problem into manageable components through network models, nodes representing resources and locations, and edges representing allocation paths, making the system easier to handle while maintaining systematization

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The automated system is designed with universal applicability through configurable constraint conditions and parameter settings, allowing it to handle various complex individual cases within different operational contexts without requiring manual intervention for each scenario

Inventive Principle:

4Adaptability or versatility

If management completion site is changed due to schedule disruption, then operational flexibility is improved, but disruption to management pattern increases

Engineering Contradiction:

Improveoperational flexibilityVSAvoidmanagement pattern continuity

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by pre-establishing management completion sites as fixed constraints in the network model before processing schedule disruptions, ensuring that these sites remain unchanged even when operational flexibility is needed to respond to disruptions

Inventive Principle:

Principle #10Preliminary action

AI summary

An objective of the present invention is to create a management plan which does not change a management completion site from the original plan. Operating schedule information which is stored in advance in a storage unit is read, each path from a start site to an end site of each route which is included in the read out management schedule information is respectively represented as one node, and routes which may be managed in sequence based on site and time are connected with links, creating a network model. A node, which represents a route to which a plurality of resources may be allocated, is added to the created network, and a link is added which connects the added node to another node, while taking into account a location whereat it is possible to carry out a merge or separation operation, thus updating the network model. In order to satisfy predetermined conditions (a condition of assigning resources to all routes and a condition of not changing the management completion site from the original plan), a path group is derived which encompasses each node of the network model, thus creating a resource management plan which executes a delivery service.
