Solution Overview

Problem

In autonomous traveling type mobile objects, overlapping stop positions lead to delays as multiple objects may stop at the same time, hindering the departure of other objects and causing operational delays.

Innovation Solution

An operation schedule management device and system that acquires and analyzes schedules to determine overlapping stops, setting a stoppable range and adjusting stop locations to prevent overlaps, prioritizing earlier departure times and load considerations to optimize stop positions within this range.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If multiple mobile objects use the same stop position according to their operation schedules, then the operation schedule can be simple and easy to manage, but overlapping stops occur causing operational delays

Engineering Contradiction:

Improveoperation schedule management complexityVSAvoidoperational delay

Core Design Contradiction:

Device complexityVSLoss of time

Solution Approach 1:

The system performs preliminary determination of overlapping stops by comparing operation schedules before execution. The determination unit identifies potential conflicts in advance, and the adjustment unit pre-adjusts stop positions to prevent overlaps, ensuring smooth operations without delays

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system continuously monitors actual stop positions and times, comparing them against the operation schedule. When deviations or potential overlaps are detected, the system provides feedback to adjust subsequent stop positions, creating a closed-loop control system that prevents operational delays

Inventive Principle:

Principle #23Feedback

2Ease of operation

If stop positions are fixed according to the operation schedule, then scheduling is simple, but mobile objects may block each other's departure causing delays

Engineering Contradiction:

Improvescheduling easeVSAvoidoperation efficiency

Core Design Contradiction:

Ease of operationVSProductivity

Solution Approach 1:

The system introduces dynamic adjustment to fixed stop positions. While the operation schedule maintains fixed nominal stop positions for simplicity, the actual stop positions are dynamically adjusted within a stoppable range based on real-time conditions, such as the presence and departure status of other mobile objects

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The stoppable range is divided into multiple candidate stop positions. The system segments the continuous space into discrete options, allowing the adjustment unit to select appropriate stop positions that prevent blocking while maintaining operational efficiency

Inventive Principle:

Principle #1Segmentation

AI summary

An operation schedule management device includes an acquisition unit (401), a determination unit (402), a setting unit (403), and an adjustment unit (404). The acquisition unit (401) acquires an operation schedule (600) of each of a plurality of mobile objects. The determination unit (402) determines presence of an overlapping stop indicating that a plurality of mobile objects stop at the same position at the same time on the basis of the operation schedules (600). The setting unit (403) sets a stoppable range in which a plurality of mobile objects are able to stop at the same position. The adjustment unit (404) adjusts stop locations of the mobile objects such that the stop locations do not overlap in the stoppable range when the determination unit (402) determines that the overlapping stop is present.
