Vehicle Operation Management Apparatus Delay Determination Suspension
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
After operational improvements, it takes time for delay times to return to within allowable ranges, leading to unnecessary delay determinations, which can be avoided by suspending delay determination for a certain period after schedule adjustments.
Innovation Solution
An operation management apparatus and method that repeatedly determine delays relative to a schedule for vehicles, suspending delay determination for a specified period after schedule adjustments are made based on the results of previous delay determinations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If delay determination is repeatedly performed for vehicles, then operational status can be monitored continuously, but unnecessary delay determinations occur after schedule adjustments
Solution Approach 1:
The system performs delay determination repeatedly at scheduled intervals to monitor operational status, but introduces a suspension mechanism that temporarily stops this periodic action after schedule adjustments. This resolves the contradiction by making the periodic determination conditional - it continues normally for reliable monitoring but pauses after adjustments to avoid unnecessary evaluations during the transition period when delays are expected.
2Measurement precision
If delay determination is performed immediately after schedule adjustment, then current status can be assessed, but redundant calculations occur during the adjustment transition period
Solution Approach 1:
The system performs a preliminary assessment by detecting schedule adjustments and proactively suspending delay determinations before unnecessary calculations occur. This preliminary action identifies the transition period and prevents redundant measurements, thereby maintaining measurement precision when needed while improving overall operational management efficiency by eliminating wasteful computations during expected delay periods.

AI summary
An operation management apparatus includes a controller configured to repeatedly determine a delay relative to a standard schedule, with respect to a vehicle operated in accordance with the schedule, the controller suspending determination of the delay for a certain period of time in a case in which the schedule is adjusted according to a result of determination of the delay.
