Solution Overview

Problem

Conventional demand-responsive transport systems fail to consider the delay time impact on existing customers when incorporating new transportation requests into existing plans, leading to inefficiencies and customer dissatisfaction.

Innovation Solution

An information processing method that calculates and presents boarding and disembark delay times to existing customers due to the incorporation of new transportation requests, allowing for a better understanding of the generated delays.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If the detour insertion method is used to incorporate new customer requests into existing transportation plans, then transportation efficiency is improved through route sharing, but delay time is generated for existing customers

Engineering Contradiction:

Improvetransportation efficiencyVSAvoiddelay time for existing customers

Core Design Contradiction:

ProductivityVSLoss of time

Solution Approach 1:

The system calculates and presents delay time information to existing customers when their transportation plans are modified due to new requests. This feedback mechanism allows customers to understand the impact of route sharing on their schedules, enabling informed decisions about whether to accept the modified plan with delay or request alternative arrangements.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The transportation plan is made dynamic and adjustable based on real-time requests. The system continuously evaluates existing plans against new customer needs, inserting boarding/disembarking locations optimally to maintain route sharing benefits while minimizing delay impact on existing customers.

Inventive Principle:

Principle #15Dynamics

2Reliability

If the last insertion method is used to incorporate new customer requests, then existing customer schedules are maintained, but transportation efficiency is reduced due to lack of route sharing

Engineering Contradiction:

Improveschedule reliability for existing customersVSAvoidtransportation efficiency

Core Design Contradiction:

ReliabilityVSProductivity

Solution Approach 1:

The system applies partial detour insertion only when beneficial - new customer boarding/disembarking locations are inserted into existing routes only when this enables route sharing with multiple customers. When insertion would not create route sharing opportunities, the system reverts to last insertion method, thus partially applying the detour method to maintain both efficiency and reliability.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

An information processing method by a transportation plan creation server includes: acquiring a transportation request including a desired boarding date/time of a new customer who desires to be transported by a vehicle; acquiring an existing transportation plan including a boarding date/time and a disembark date/time of an existing customer; calculating at least one of boarding delay time and disembark delay time indicating time delayed from at least one of a scheduled boarding date/time and a scheduled disembark date/time of one existing customer in the existing transportation plan by incorporating the transportation request into the existing transportation plan; and outputting at least one of the boarding delay time and the disembark delay time.
