Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fleet management systems lack an effective method to utilize risk profiles to assess and compare the performance levels of vehicle operators across a fleet, based on historical vehicle event data.
Innovation Solution
A system and method that utilize risk profiles to characterize the likelihood of vehicle events, allowing for the determination of performance metrics for individual vehicle operators. These metrics are compared to aggregated metrics of a set of operators, enabling comprehensive performance evaluation and management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If fleet management systems monitor vehicle events and operator performance, then performance assessment capability is improved, but the system lacks effective methods to utilize risk profiles for comparative analysis
Solution Approach 1:
The patent introduces risk profiles as an intermediary element that mediates between raw vehicle event data and operator performance assessment. The risk profile serves as a contextual framework that enables meaningful comparison by translating historical event patterns into standardized risk metrics, thereby resolving the inability to effectively utilize available data for performance evaluation.
Solution Approach 2:
The system performs preliminary analysis by pre-establishing risk profiles based on historical vehicle event data before conducting performance assessments. This preliminary action creates a reference framework of expected risk patterns that enables more accurate real-time performance evaluation by comparing actual operator behavior against pre-computed risk benchmarks.
2Measurement precision
If the system determines performance metrics for individual operators, then performance evaluation capability is improved, but the ability to compare individual performance with aggregated fleet performance is insufficient
Solution Approach 1:
The risk profile framework serves multiple functions simultaneously: it characterizes individual operator performance, enables comparison with aggregated fleet performance, and provides a standardized basis for cross-operator analysis. This multi-functionality resolves the limitation by making the same risk profile infrastructure adaptable to both individual assessment and comparative analysis needs.
Solution Approach 2:
The patent adds a new dimension to performance analysis by introducing risk-based metrics that transcend simple event counting. By incorporating risk profiles that consider context, severity, and patterns of vehicle events, the system creates a multi-dimensional performance space that enables more nuanced individual assessment and meaningful comparison with fleet aggregates.
3Loss of information
If the system uses historical vehicle event data for risk characterization, then data-driven assessment is improved, but the method to quantify and compare performance levels is lacking
Solution Approach 1:
The system implements feedback loops where historical vehicle event data continuously refines risk profiles, which in turn improve performance assessment accuracy. The aggregated performance metrics feed back into updating risk characterizations, creating a self-improving system that becomes more efficient at quantifying and comparing performance levels over time as more historical data is processed.
Solution Approach 2:
The patent transforms raw historical event data into meaningful performance metrics by changing parameters from simple event counts to risk-weighted measurements. This parameter transformation enables efficient quantification by converting voluminous historical data into condensed risk profiles that capture essential performance characteristics without requiring analysis of every individual event.
Data Source
AI summary
Systems and methods for using risk profiles for fleet management of a fleet of vehicles are disclosed. Fleet management may include determining the performance levels of particular vehicle operators. The risk profiles characterize values representing likelihoods of occurrences of vehicle events. The values are based on vehicle event information for previously detected vehicle events. Exemplary implementations may: receive, from a particular vehicle, particular vehicle event information for particular vehicle events that have been detected by the particular vehicle; determine one or more metrics that quantify a performance level of the particular vehicle operator, based on the risk profiles; compare the one or more metrics for the particular vehicle operator with aggregated metrics that quantify performance levels of a set of vehicle operators; and store, transfer, and/or present results of the comparison.
