Network Analyzer Integrating Inquiry and Device Logs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for diagnosing network failures often rely on inaccurate user descriptions, leading to improper countermeasures due to the lack of precise failure situation depiction, which can be alleviated by consistency checking with device logs but increases the maintenance operator's workload.
Innovation Solution
A network analyzer that processes both inquiry statements and device logs to select answer candidates and calculate their respective degrees of certainty, determining an accurate answer by integrating the certainty values from both sources, thereby reducing reliance on user accuracy and operator workload.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If consistency checking with device logs is performed to improve diagnosis accuracy, then measurement precision is improved, but loss of time increases due to increased maintenance operator workload
Solution Approach 1:
The system enables self-service by automatically performing consistency checking between inquiry statements and device logs using a computer-implemented algorithm. The processor autonomously compares the inquiry statement against device log data without requiring manual operator intervention, thereby maintaining high diagnosis accuracy while eliminating the time burden on maintenance operators.
Solution Approach 2:
The patent replaces the manual mechanical process of consistency checking with an automated computer-based system. The processor executes algorithms to automatically compare inquiry statements with device logs, substituting human operators' manual analysis with automated computational processing, thus achieving both accuracy and efficiency.
2Productivity
If automated computer search is used to generate answer statements, then productivity is improved, but measurement precision deteriorates due to inaccurate user descriptions
Solution Approach 1:
The system implements feedback by performing consistency checking where the processor compares the inquiry statement against device log data and uses the consistency result to adjust or validate the generated answer statement. This feedback mechanism ensures that automated responses are verified against actual device states, maintaining high diagnosis accuracy while preserving automated productivity.
Solution Approach 2:
The consistency checking process acts as an intermediary between the automated computer search and the final answer generation. The processor uses device log data as an intermediate reference to verify whether the automated search results align with actual device states, thereby ensuring accuracy without sacrificing productivity.
Data Source
AI summary
A network analyzer includes a storage and a processor to provide an answer to inquiry including an inquiry statement and device log. The storage stores first information indicating relation between a previously received inquiry statement and an answer for the inquiry statement and second information indicating relation between previously received device log and an answer for the device log. The processor selects a first answer candidate for a new inquiry statement and calculates a first degree of certainty of the first answer candidate based on the first information. The processor selects a second answer candidate for new device log corresponding to the new inquiry statement and calculates a second degree of certainty of the second answer candidate based on the second information. The processor determines an answer based on the first answer candidate, the first degree of certainty, the second answer candidate, and the second degree of certainty.
