Reverse FTA Analysis

Traverse FTA trees built from past critical failure cases in reverse, presenting hypotheses of critical failure reachability from current sensor data

Expected Challenges

When CBM sensors detect anomalous values, determining whether the anomaly is 'merely a temporary fluctuation' or 'a precursor to a critical failure' is one of the most important and difficult decisions in equipment maintenance. This judgment requires advanced reasoning to trace FTA (Fault Tree Analysis) trees built from past critical failure cases in reverse, evaluating the reachability of critical failures from current sensor states.

Integration with Existing Workflows

When the CBM system detects a sensor anomaly, reverse FTA analysis is automatically triggered. It integrates with the CBM dashboard and requires no additional setup. Starting from the anomalous sensor data, it traverses FTA trees registered in the critical failure catalog in reverse.

Leveraging KDG Knowledge

KDG has accumulated a catalog of FTA trees built from past critical failure cases. Each FTA tree structures the causal chain from top events (critical failures) to basic events (initial anomalies), managed in a data structure optimized for reverse traversal.

Expected Challenges

IoT sensors (vibration, temperature, current, pressure, etc.) installed on manufacturing and plant equipment continuously generate data 24/7, but distinguishing 'anomalies requiring immediate action' from 'normal-range fluctuations' requires the judgment of veteran engineers who understand each equipment's characteristics and operating conditions.

Integration with Existing Workflows

This solution leverages the existing sensor monitoring infrastructure as-is. Sensor data is automatically collected 24/7 and stored in the system. After data collection, automated checks are performed based on thresholds configured for each piece of equipment.

Leveraging KDG Knowledge

KDG systematizes the diagnostic knowledge cultivated by veteran equipment maintenance engineers, including knowledge for estimating failure modes from vibration frequency characteristics, predicting degradation rates from temperature trends, and identifying root causes of anomalies from multi-sensor correlations.

Expected Challenges

CBM (Condition-Based Maintenance) systems are essential tools for equipment condition monitoring and diagnostics, but conventional systems were only available in office PC environments, preventing field engineers from checking equipment status in real time during rounds.

Integration with Existing Workflows

Field engineers simply open the Mobile CBM app on their mobile device (smartphone or tablet) and scan the QR code attached to the equipment to access that equipment's sensor data, diagnostic results, and maintenance history.

Leveraging KDG Knowledge

The knowledge referenced by Mobile CBM is the same KDG knowledge base as the CBM dashboard. Vibration diagnostic standards, failure mode DB, maintenance decision criteria, and trend analysis knowledge are all accessible from mobile devices.

Expected Challenges

Manufacturing and plant equipment maintenance plans are required to transition from conventional TBM (Time-Based Maintenance) to CBM (Condition-Based Maintenance), but this transition decision requires advanced knowledge that comprehensively considers equipment failure mechanisms, operating conditions, maintenance costs, and risks.

Integration with Existing Workflows

Simply submit existing maintenance plans (Excel or maintenance management system data) to the system to start diagnostics. No changes to existing maintenance workflows are required.

Leveraging KDG Knowledge

KDG systematizes the knowledge needed to optimize equipment maintenance plans, including failure modes and degradation mechanisms for each equipment type, TBM-to-CBM transition criteria, maintenance interval optimization logic, parts selection criteria, and cost optimization approaches.

Expected Challenges

In supply chains for food and other goods, various disruption risks occur regularly, including supplier shutdowns, port closures, quality issues, sudden demand changes, raw material price surges, and geopolitical risks.

Integration with Existing Workflows

This solution does not change existing procurement and logistics workflows. It can be used simply by opening the SCM monitoring screen when disruption events are detected through supplier notifications, news alerts, or internal reports.

Leveraging KDG Knowledge

KDG systematizes veteran knowledge for disruption response across six categories. When an event occurs, KDG receives a 'Situation Context' combining impact propagation results with current facts, and searches for the most relevant knowledge to respond.

IT Infrastructure Anomaly Monitoring (IFT)

Detect anomalies in servers, networks, and cloud infrastructure, supporting failure prediction analysis and response

Expected Challenges

When IT infrastructure failures occur, initial triage (identifying failure points and determining escalation targets) is the operations team's most critical and time-sensitive task. However, in environments where servers, networks, storage, and batch processes are complexly interdependent, identifying the true failure point from logs and alerts requires expert knowledge.

Integration with Existing Workflows

Upon receiving logs and alerts from monitoring systems, the system automatically begins impact propagation analysis on the dependency graph. It integrates with existing monitoring infrastructure (Zabbix, Datadog, CloudWatch, etc.) through alert integration, requiring no changes to the monitoring setup.

Leveraging KDG Knowledge

KDG systematizes the incident response knowledge cultivated by veteran IT infrastructure engineers across six categories, including runbooks, escalation criteria, past incident cases, message code meanings, configuration standards, and batch dependencies.
