Procedure extraction system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In abnormality diagnosis of facility equipment, such as air-conditioning equipment, the traditional method of saving all steps of an engineer's analysis procedure in a database leads to unnecessary steps being saved and retraced, increasing the workload for engineers as irrelevant steps are included.
Innovation Solution
A procedure extraction system that includes an analysis log storage, a graph creation unit, a region specification unit, and an output step extraction unit to extract only the steps necessary for determining the cause of abnormality by creating a graph and specifying relevant regions, thereby isolating the steps required for analysis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all steps in the engineer's analysis procedure are saved in the database, then complete procedural information is preserved, but irrelevant steps are also saved leading to increased workload when referencing past incidents
Solution Approach 1:
The system extracts only the relevant steps from the complete analysis procedure by identifying the causal chain leading to abnormality determination. The extraction unit selectively removes irrelevant steps while preserving the essential diagnostic pathway, thus maintaining reliability without the burden of complete procedural documentation.
2Ease of operation
If the engineer manually extracts only the relevant steps to save in the database, then the workload when referencing past incidents is reduced, but it takes much workload for the engineer during the extraction process
Solution Approach 1:
The system performs automatic extraction of relevant steps without requiring manual intervention from the engineer. The extraction unit autonomously analyzes the stored procedure, identifies the causal relationships between steps, and extracts only the relevant portions, thereby eliminating the time-consuming manual extraction process while ensuring consistent and accurate results.
Solution Approach 2:
The manual mechanical process of step extraction by engineers is replaced with an automated information processing system. The extraction unit uses computational methods to identify and extract relevant steps based on causal relationships, substituting human cognitive effort with automated analysis that is both faster and more consistent.
3Loss of information
If all steps are saved in the database, then no information is lost, but the same useless steps are repeatedly taken despite referencing past incidents
Solution Approach 1:
The system extracts only the essential steps that lead to abnormality determination by identifying causal relationships. This selective extraction removes redundant and irrelevant steps while preserving the core diagnostic information, thus maintaining information integrity while significantly improving diagnostic efficiency by eliminating repetitive useless steps.

AI summary
A procedure extraction system will be provided which can extract a procedure related to determining the cause of abnormality in facility equipment from analysis procedures in accordance with which the operator analyzes the operating conditions of the facility equipment. The procedure extraction system includes an analysis log storage to store a procedure in accordance with which an operator has analyzed an operating condition of facility equipment using operation data relating to the operating condition of the facility equipment, a graph creation unit to create a graph using the operation data, a region specification unit to specify at least a region of the graph, and an output step extraction unit to extract, from among steps included in the procedure stored in the analysis log storage, a step necessary for creating the graph including the region specified by the region specification unit.
